What do you think of this 2.5in exhaust system (on a 98 impreza L) Would you buy it??

lotus2843 · 08-12-2005, 06:07 PM

I just built this exhaust system for my impreza, Its a 2.5 inch press bent cat-back with a heavy duty flex joint, 24 inch resonator, and stainless N1 style muffler. I can sell these for $200 plus shipping and its a direct bolt-on. Or if your in the CNY area i can built anything you want.

If you have anything you think i should change on the next system i make let me know. I can make this system without the resonator of corse. With the police around here i dont want to get to much attention

YEAH, DON'T F*** WITH THE NY STATE TROOPERS!

My '98 L loves you for this and for the price, my wife will love me. My only question is how well does it work?

I'm very interested, but with some performance numbers, I'd buy in a flash.

also, just 'cuz your so close and I know you went...how was STPR?

piker28 · 08-12-2005, 09:14 PM

why would you want such big piping on an L, thats just silly plus youll lose tons of low end and not gain that much high end

cueball89 · 08-12-2005, 09:32 PM

how close is the can to the rear bumper? will it leave black marks? How does it sound, and do you notice a difference in preformance? Is press bent as good as mandrill? Im in sidney where in ny are you located?

svek · 08-12-2005, 11:49 PM

2.5" is too big for the 2.5L engine, thats gotta suck for the little ej22

2slofouru · 08-13-2005, 12:07 AM

It's actually a good size for his ej22T. I would definately wait until after the flex joint to go up to 2.5" from the stock diameter though. That way there won't be so much heat released at the joint. With the long resonator and muffler in there it should be plenty of "back" pressure for a n/a 2.5. Thanks for giving us all the chance at a good price, at least someone is trying to save us all a few $.

svek · 08-13-2005, 12:20 AM

ohh i didnt know it was turboed. being in the n/a forum and yah...

ej25power · 08-13-2005, 12:42 AM

Do any of you guys know if the cat pipe on the L is the same shape as the RS's? I'm trying to talk to this guy about making some track pipes that are heavily resonated

I guess he only has an L catpipe to copy...so if it is the same shape, we'll be in luck.

If not..someone in his area want to give him a stock RS cat so he can make up a jig?

Mechkiller31st · 08-13-2005, 12:58 AM

Hmm I got a 2.2L Wagon from 98... I have been looking to get rid of the Borla for something a bit louder. I really would like to hear a sound clip. Plus I Would really like to see some numbers so We can see the Gains and Losses of putting a 2.5" exhuast on a 2.2L. Is it possible to show a dyno result before and after? I would love to have this for $200 plus shipping to Chicago.

A common misconception. According to Dynomax (and you'd probably find very similar tables on other exhaust manufacturer's websites) a 2.5L engine making 150hp should run a 2.25" single exhaust, and if it's making 200hp it should run a 2.5" single exhaust.

where did we get 200hp from?

I guess by CAI and nitrous... I rather keep some low end by using 2.25" though

lotus2843 · 08-13-2005, 12:52 PM

Well this is the story, my 98 impreza is not turbo, it has the ej22, And dont take this as a sales pitch, but not only did i gain small amounts of low end power, i gained a whole lot of high end, I dont have dyno results, nor will i ever. I used 2.5 because im in the prosses of building a turbo kit. The exhaust system has also given me 2-5 mpg+ daily driving (not on highway). And just because i have built mine with 2.5 inch pipe, and a resonator dosent mean every system has to be the same, i can build it from 2 inch - 3 inch with or without the resonator. I will get a sound clip asap but someone please host it for me. $200 plus shipping should be an awsome price considering what i have seen subaru exhaust systems go for, And unlike other brands, i will be building every exhaust system to exact fit to my 98 L. I also have 4 different stainless mufflers and various tips to chose from

lotus2843 · 08-13-2005, 01:04 PM

AND... The muffler does not hit the bumper, and it should not leave carbon on the rear bumper either. You should also be 100% emissions safe with this system as it only removes the second cat.

I was also asked about "Duals" and yes, i can Y the exhaust after the rear diff and run simulated dual exhaust. This will add ~$100- ~$120 to the total of the system.

Ask any questions you may have and i will Quote a a price accordingly

lotus2843 · 08-13-2005, 01:06 PM

I am located in Ovid NY, if you are local just call my cell 607-342-1796 and make an appointment for a full custom system installed. Here is another example of a recent exhaust system i built.

HolyCrikey · 08-13-2005, 02:33 PM

A few things:

That bent-up tip ricer crap is hideous. Just my opinion.

Curiously, why would you want to run a flex section section instead of piping?

I think your exhaust system is fairly priced for what it is, but what materials are you using anyway when it comes to the piping? Again, no offense, but I've seen far better weld joints and much better crush bends for much much cheaper.

And to cueball89, crush bends are not as good as mandrel. However, this depends on the application. If the bend is minor (like the bends in the midpipe), they are usually less than 15 degrees, and most people can crush bend them well enough to make them look mandrel bent. However, when it comes to axleback sections of most subie chasis, mandrel bends are always going to be superior, but you'll obviously have to pay more. But IMO, it's most definitely worth it as they flow better.

Again, I don't mean to be a naysayer on this thread.

You said that a 2.5" exhaust is too big for a 2.5L. There are a number of us, myself included, putting out 200+hp from our N/A 2.5L engines, hence 2.5" exhaust is not too big. You made a blanket statement, I countered your blanket statement.

Pat

piker28 · 08-13-2005, 02:56 PM

i think its a tad bit to big for the RS and way to big for an L but again its your car

and to the maker of the thread, IBTL, you are trying to sell a product therefore need a vendor liscense

i can see that yes. but the old arguement is about the stock to slightly modded ej25. 200hp out of the ej25 i wouldnt call slightly modded. but yes i do agree that 2.5" piping is probably perfect for a 200hp application. just as the 2.25" is perfect for the 165hp application

edit- to the seller of the exhaust setup. is this mild steel or stainless? and could you do titanium?

lotus2843 · 08-13-2005, 04:43 PM

Im not sure if i can migweld titanium with wild steel wire, i use all aluminized pipe, As for the welds on the flang of the flex joiny, i welded it inside and out. where the resonator is i messed up by not sanding the paint off the edges where i needed to weld. If you dont like the way the muffler is setup thats fine. I didnt like it when i first started seeing the style pop up but it has grown on me. And as for a vendor lisence.. HAHA i might as well be doing this for charity for the price im asking, can you even find a direct fit axle-back for $200+ shipping? Also, i used a flex joint because the car had a factory doughnut-type flex joint so i assumed there had to be something there to flex, It hurts nothing, and will last the life of the system. And again... if you are questioning the welds there is no reason to. they are all very strong and will never crack or break.
