Default Sound Clip Comparison: Borla, Stromung, Random Tech vs MRT vs Brullen

I know that a full Header Back Exhaust is a big purchase. One of the most important factors to consider when purchasing your exhaust is exactly how it will affect the natural tone and sound characteristics of your car.

As we all no unfortunitely the installation of a full header back exhaust may provide a few more horsepower and smooth out the power band a little but overall the gains are negligable compared to the money you spend. In my mind the biggest effect an exhaust has is on sound. In other words when spending this kind of money for an exhaust you better be happy with what you end up with.

To help with this I have compiled 3 fairly good qaulity sound bites of 3 of the most popular and talked about full exhausts on this board and are listed below:

Borla Headers - Random Tech Cat - Stromung Dual Tip





MRT Headers - MRT Cat - 2.25" Mid Pipe - N1 Style Straight Through Muffler



PT1001 PowerTech N1 Style Muffler





Brullen Header Back;: Followed By :; Borla Headers - Random Tech Cat - Stromung Dual Tip



Enjoy

I'll be the first to admit, that with the Borla header, Random Tech Cat, and a HKS sport exhaust, the car sounds stellar. Its deep and has a nice loud grumble to it, but it is loud as hell when you floor it. It doesn't drone at all when cruising on the highway though, so thats a plus.

Thats exactly the reason I switched from MRT to Borla. Actually thats the only reason I switched to Borla. No exhaust system is going to make my 3100lb car feel fast. So it may as well sound good

There are small subtlties that you can hear in real life that made my decision hands down for the Borlas when compared to the MRT and the Brullen setup.

Its very hard to record and reproduce the good low frequency reponse that all of the exhausts emmit. However the Borla setup takes the cake when your listening in real life.

How much of the sound is based just on the rear section?

What would the MRT header sound like with different muffler.

well... with the MRT muffler it's raspy, but throaty. Not to too loud. With a modified wrx muffler, it's too quiet.

Was it just the recording procedure, or do all of the exhausts produce that metal-e vibration sound?
It might just be hearing a recording of them, I'm sure it sounds better in real life.

I really love my setup Borla headers, R.T cat, Borla catback. The sound is beastly (deep growl with some rasp). From the clips, I don't think any other aftermarket headers can beat the sound. A resonator would probably clean up the rasp a bit and mellow it out, so my next catback will definitely have one.

with headers, high flow cat, and wrx muffler I'm amased at how quiet it really is... I'm wondering how much performance I'm loosing w/ the muffler, and the original was obviously much less restrictive.

The metal vibration sound that you hear with the Borla recording was a heat shield vibration that was actually discovered on the owners car by listening to the sound clip.

The MRTs rasp is definitely from the N1 style muffler. However the equel length of the MRT header primaries and secondaries really smooths out the exhaust pulses taking away that growly sputteriness found in the Borlas.

As much as I appreciate what you've compiled, Brad, I don't think it tells the full story. As we've probably all noticed, our exhaust sounds way different under load than it does just revving it in a parking lot.

What would be really nice to have is some clips of cars actually on the road. Of course, that makes the recordings more difficult, but if it could be done it would be sweet. A recording from in the car (radio off , windows up), and then an external recording (which would require a chase car and some coordination). I'm visualizing a couple scenarios - the two cars nearly side-by-side, with the recording car hanging back about 3/4 of a car length so the exhaust is not blocked, recorded car downshifts and takes off at WOT while recording car stays at constant speed. If the recording car is quiet (borrow Mom's Buick, maybe?) then it could accelerate too, but we don't want its noise to interfere with the target's noise, ya know? The second scenario would have to involve some engine braking - my MRT exhaust isn't all that loud normally, but under engine braking it has a pretty nice growl to it.

I've got a scoobysport and made some clips a long time ago.
Too lazy to cut out the silence and everything.
Its a Scoobysport on 2.5in midpipe. No other exhaust mods. I taped a computer mic on my bumper and used a laptop to record.

Redlining 1st and 2nd gears

Mostly 3k shifts with a 4k in the end

No load

Its pretty quiet compared to some of the exhausts I've heard.

I thought about hooking up the recording equipment to the Power Convertor and laying in the trunk while holding the mic and having a friend romp on the car.

Unfortunitely my friend would agree to allow us to use his recording equipment this way.

Patrick - I wish I could have gotten a recording of the MRT exhaust in action with load. There was a sweet sputter cough that happened in between shifts. It sounded so cool.

Just thought i'd post what I had.

my setup on an 02rs is borla headers, custom 2.25 midpipe unresonated, scoobysport axleback. stock cats.
This setup is somewhat loud, however far from obnoxious because it is very deep and bassy. very choppy. I love it
Combined with the cobb intake my car makes a pretty sweet note when i get on it!

it sounds great inside the car, but when i let my buddy drive it around me so i could hear it from outside i was so psyched on how it sounds! gave me a new appreciation.
the borla headers completely transformed the sound, now it sounds more like a wrx with a turbo-back.

Default My Setup(video)

Here is a short video of my setup. TWE header + cat mated to Brullen quiet catback.

I'll volunteer my dv camera to do the in car and chase sounds if everyone wants to come to west-central PA.

right click and save as...(4.5MB .mpg)

It should work fine in Windows Media, but if you have problems viewing...try quicktime.

Question

Question:

Does anyone know if the stock cat pipe on a MY98 L has the same diameter as a MY98 RS?

Just wondering since I want to increase flow a little without going to an aftermarket high flow unit.

FYI, I'll be getting the Borla header as well (single manifold outlet for the L).

-Mike.

Brullen Sound Clips
Here are some sound clips from just a brullen exhaust set up, I dont know how extensive it is ie header, cat, muffler etc, but the trick is to really get a feeling for what this sounds like,
1.) go buy a good computer Subwoofer
2.) turn the subwoofer all the way up
3.) allow your house to shake.

Yes it does sound like that, i only have a brullen 2.5" pipe and muffler, and it sounds real good. I'm gonna get a gen4 header sooner or later, i remember someone had a link to a website for the headers at around $300, does anyone remember it? I forgot to bookmark it

Jared: dropped you an IM, but you're "away" so I figured I'd bump the thread for everyone else...

Do you or anyone else here still have the TWE clip? That's basically the exact setup I want and I'd love to hear it.

Thanks,

The setup on my L is as follows:

Borla headers, stock cat, 2.25" mid pipe, 5Zigen muffler.

The sound is incredible. Meanest sounding 1.8 around.
