Thumbs up Long overdue: Brullen Header-Back Exhaust Review

That is, long overdue, because, why didn't I get this sooner?

I'll start from the beginning. At first glance, from muffler up, the muffler is an EXCELLENT wide, black rectangular cylinder of steel, with two sexy chromed tips out the back. That, in itself is one of the best dress-up mods I've done so far.

Moving along, the cat-back is a deliciously straight pipe of black high-temp paint-covered stainless steel, with beautiful welds at every juncture. It replaces the 2nd cat straight away, and was a very easy, very clean install. (I did the install in 2 parts.)

Next is the catalytic converter. One (actually good looking) heat shield grazes the bottom, and just before both flanges are O2 sensor bungs. Holding the stock cat and this high-flow cat side by side, it just screams better flow, just after and just before both flanges it flares out to a good double the size of the piping at both ends. As a note, I only needed to extend the first O2 sensor, which was fairly easy given a crimper and some butt connectors, and a mess of electrical tape.

Now for the best part. The headers. Shiny stainless steel in slow bends and excellent welds, this is definitely the stuff. Both branches from the exhaust ports meet up at the same point, no double-backing from the right headers as in the stock ones. Only gripe here is they didn't provide a gasket for the left header pipe to main header pipes juncture, and have you put liquid gasket there. No biggie, haven't had problems. Also, make sure the additional plug for the O2 sensor bung on the headers is tight, Loctite it if you're not sure! (You don't want it loosening itself and flying out while going 50, like me. )

Now, the moment you've all been waiting for, performance. In my 2.5RS, I noticed the slightest of low-end losses (but don't we have enough to spare anyway?), probably because I have 2.5" cat-back anyhow. But, holy crap, once its up there, you just keep going. I was doing 65 before I knew it, in about 100 feet. Its almost too much to handle around my town.

And the sound is unlike any V8 you've ever heard. Low pitched and rumbly, at WOT you and everyone else around you knows you're going fast. I have had many comments on it, and its not loud enough to wake the neighbors. (Unless you like redlining it down your street).

Overall, its the best mod I've done for my car, and props to Brullen. 50 miles so far and no CEL yet! And the whole install only took around 4 hours to do. I reccomend this system, and with the entire thing you don't need to have any welding done. All hardware is included, too. Except for liquid gasket.

Any questions I'd be happy to answer.

Default Part numbers and prices?

Best dealer to buy from. This is specifically made to fit the '02 RS2.5? Can you put a MRT header on this brullen w/o mods?

I got mine from GTBGUY. Deal through him, he's a great guy. I have no idea if it MRT headers will fi the Brullen cat and cat-back. I don't know if mine was made for the '02, but talk to GTBGUY (iON Performance) on the boards, he'll help you out.

The Brullen header and cat-back was certified and tested to fit an '02 RS... using my car for measurements If you're thinking about a header back then go with Brullen, it completely transforms the car. Their customer service is great too, if you had any idea how much time and effort they put into solving that whole CEL light issue you'd realize the dedication to their customers.

How much did you pay for your Brullen engine back exhaust? I heard they were an eye gauging $1425.

The MRT set is $560 + shipping for the full exaust. I think MRT did have a problem with CEL for cat efficiency but I understand that has been taken car of by ceramic coating the header section. Did I mention these exhaust have shown a top end power gain of around 20 hp to the wheels, and I'm not talking about a 20hp gain for only 500 rpm. This gain exist from about 3500 RPM all the way to redline +- about 3hp.

No the MRT headers meet the cat in a different location then the Brullen. If you go with MRT you need at least the Headers/Cat/Midpipe. However any axle back muffler section made for your car will fit as the MRT midpipe meets the muffler section in the same place as the stock exhaust.

"And the sound is unlike any V8 you've ever heard. Low pitched and rumbly, at WOT you and everyone else around you knows you're going fast"

I have attached an audio comparison of a Brullen full exhaust compared to a Borla Full exhaust. Brullen is first followed by the Borla. I like the BMW like growl of the Brullens but nothing sounds more like a performance V8 then the Borla exhaust.

Eh? I hope that's just the cat-back.. I paid more than that for my Brullen cat-back..

I heard Deus' RS after the header install.. Wow that thing is mean! Definitely more overall angry grumble than my cat-back system.

LordBass,
Nope, that price is for the whole MRT system. So, why doesn't everybody have one? Perhaps they are scared of mild steel, or attracted to stainless?

The MRT systems have to come all the way from Australia. There are dealers here in the US that can get you a system for that price in a few weeks, though.
Most performance testers (Cobb) prefer mild steel properties for a header. You can still protect it, which is why most people opt to have the MRT header coated. The coating helps performance even more by keeping the heat in and the exhaust flowing faster.

Hmm... that MRT system sounds worth looking into.

Yes, that Brullen price is eye-gouging, but I have no doubt that just the SOUND of the Brullen is worth the price of admission.

As the installer of Deus' system, I'll give my impressions. The design and craftmanship of the Brullen system is INCREDIBLE. The welds are quite possibly the cleanest I've seen on stainless, with nearly no leftover spatter or flux from manufacturing. Everything fit together like a GLOVE once under the car.

I haven't driven the car, so I can't account for any gains(though I hear about them daily), however, upon initial startup, the SOUND of the car was incredible. Low and fairly quiet at idle, deep and snarling under load. The sound is comperable to a quiet Group N rally car.

My overall opinion? I'd buy it!

Wow. If I ever start a business I am hiring whoever marketed the Brullen exhaust.

I will be dynoing the MRT and Brullen full exhausts back to back to see which one performs better. I guess then and only then can I comment as to which has superior performance. From my experience with exhaust system something tells me the MRT Equel length Header exhaust will flow better. I guess the only way to tell is to see where and how much the power curve is aided by each exhaust.

Honestly though, for my full MRT Engine Back Exhaust I paid literally a little over 1/3 the cost of what they are charging for the full Brullen set. To me if I get more then 1/3 the power gain that the Brullen exhaust provides I will be satisfied that I made a very cost effective purchase.

By the way I got word that MRT is now Ceramic Coating the header section of their exhausts. It was mentioned that these exhausts are made from mild steel. I wanted to confirm that they are but also add that MRT alloy coats the full exhaust and paints the pipes black with high temp paint. In other words no rust from road grime.



I went for the dual tip.

Thanks
Brad

Sure, MRT if you want a CEL, but I still haven't had any problem with my Brullen. Besides, at that price, its a matter of you-get-what-you-pay-for.

Also, is it just me or does that Borla sound like a Honda? I like the first sound clip better, it is much deeper and has a better tone.

And Soob, after hearing about what you do to your cars, you wont be driving it.

Yugh. That looks horribly ugly, and little more than a hunk of metal. Especially that tip, is that tinfoil?

My Brullens are covered in black high-temp paint also, and its stainless steel all the way through. Not in visual appeal, but the Brullen looks like it would be better, and of higher quality than that.

Also, I heard people waiting more than a year for their crap from MRT.

DeusExMachina-say what you need to say to justify the $1425 bill that your probably still trying to pay off with your credit card. Funny how you try and bust on the exhaust tip of the MRT set. I could still afford to buy a Stromung Axle back to put into the combination and my exhaust would still come in cheaper then your Brullen set. By the way your CEL argument against MRT isn't valid any longer. As mentioned above they are now Ceramic Coating the Header section. It wouldn't matter for me anyway since my car is a 99 which has looser OBD-II standards. DeusExMachina do you even know what OBD-II means?

Can anyone else confirm that Brullen has any stainless steel in it other then the exhaust tip?

We'll let the dyno results prove which exhaust performs better. I guess only then will you find out whether or not you got what you payed for.

$1425 just sounds like a lot of money to spend if your only getting a sweet V8 like sound. We'll see in about 2 months if thats all your getting.

How do you plan to change the oil filter? Looks like those headers won't stay too pretty for long.

Um, does somebody need to point out the the exhuast system is UNDERNEATH the car? Who gives a rat's ass what it looks like? Make it perform (and not sound like a tin can) and I'll be happy.

And I'll second the statement that mild steel isn't a problem. I had a mild steel exhaust on my previous car for 3 winters with zero rust.

My only problem with the MRT system is that I'll need to change my exhuast flanges if I buy just the header.

Heres the picture I was thinking of when I posted above.

laymen-I don't think you could just buy the header. You would need the Headers/Cat/and Midpipe. In otherwords everything but the Axle Back. This would cost you under $500 shipped. The Axle back is another $105 if you buy these seperately.

I could understand the complaints about mild steel beeing exposed to the elements. Fortunitely for me the MRT Mild Steel Exhaust is well protected from the elements.

Anybody see an oil filter under there anywhere?

Anyone??

Oh wait it even looks like oil from the pan will squirt all over those Mandrell Bent beauties when you unscrew the pan bolt.

I have to agree with Laymen I'd rather be passing you in a car that has a four cylinder in it and may sound like a four cylinder as opposed to riding around town in a growly "V-8 like" four cylinder and getting passed.

Where's that picture comparing arguing on the internet and the special olympics..

Sigh. Okay, everything looks like stainless steel to me, but since I don't have a laboratory to analyze it for you, MY99, I guess we'll never know.

How does attemping to insult my intelligence about the acronym for On Board Diagnostics solve anything?

The bill's no problem, I'm glad to pay it for high quality car parts. The sound and the huge gain I've felt make up for it.

Before you edited the post, I plan to change my oil just fine, and the oil isn't back where the cat is, as your picture had shown.

Also I plan on changing my oil filter with heat resistant gloves. [SARCASM] What a huuuuge pain. [/SARCASM]

By the way, they stopped having to ceramic coat the headers, because they care to solve the CEL problem with a more mechanical solution.

And finally, Layman, whats pretty about metal pipes anyway? By talking about the looks, the Brullen looks much better constructed than the MRTs.

You also chose to ignore the fact it takes a helluva long time to get the MRT exhaust, MY99.

Looks like I have to reply again. To get to the oil filter, you turn your wrist to get by the headers. That so hard? The headers do not obstruct the oil pan whatsoever.

I didn't say it magically turned the car into a pseudo V8, but it sounds BETTER than any V8 I've ever heard. That is the beauty of the Subaru flat 4's sound.

Also, you want your car to sound like a 4 cylinder? Maybe you like the sound of a tin can'd Honda. Oh wait, you did say you like the sound of the Borlas, so I guess you do.

No bickering going on here.

You said Brullen decided to fix the CEl issue by more mechanical means. What are they. Ive got a $30 way to get rid of that useless Cat efficiency light forever. A friend ordered one for his Borla set. Works perfectly.

My main point is if you have two exhausts side by side. Lets say they both make equel peak power and flatten out the curve very well. One costs $1425 and the other costs $560. Not a real hard decision for me.

I'm not going to continue to argue with you about looks because as said by Laymen I'm not concerned what the road is going to be staring up at. As expressed before I will possibly go with a different axle back with a stainless muffler. You can't argue longevity or build qaulity. We can't really argue performance because I haven't done back to back dyno runs yet. So lets put this conversation on hold until that gets done.

I was wondering if anyone would catch that picture misshap. I accidently attached the wrong one the first time. Pretty funny

Trust me... the whole Brullen is stainless, I've seen them being made.

Do you think they would honestly advertise as stainless and use mild steel . So many cynics on this board...

Dues-actually I love the sound of a V-8. Infact my dad has an 81 Camaro with a 350 bored/stroked and a Weiand 671 blower and dual 800cfm 4 barrells. For cruising and dragracing I'd choose to hitch a ride in his car any day.

I really can't stand the sound of the trumpety exhausts some people put on Hondas.

DeusExMachina-You made that comment about tin foil on the exhasut tip. I looked back at the picture and realized what you meant. Thats actually bubble wrap so the polished stainless steel doesn't get scratched in shipping. Wow that picture does make it look pretty ugly. Trust even if it costs $560 I would trust an exhaust maker that allowed their stuff to look that bad.
