I apologize, I just didn't understad the choice you were making. The reason I posted the specs of our exhaust was to put the information out there. Seems like a lot of guys are shopping the hell out of exhaust systems when in my mind the choice doesn't seem too hard to make.

An exhaust has a job to do, get the exhaust out of the engine and past the passengers so they don't die of carbon monoxide. In a performance world it is to still do this but do it with the least amount of back pressure. We do that and on top of that do it in the lighest weight complete system you can get in a material that will not rust or rot, so it is good for the lifetime of the car. I just don't get all the guys shopping systems that are heavy, don't perform and even worse aren't even made of stainless (B&B is stainless, not referring to them) and are going to rot off the cars in a matter of 5 years or less.

dave my friend just bought a turboback+up-pipe for his 2003 wrx, its light as hell!!!! i cant wait to put it on this weekend. the up-pipe seems difficult, but we got a lift and all the tools, and i along with my other friends are pretty car knowledgable... do u recommend us tackling the the up-pipe using a step by step how to and some pictures online, or do u really think a mechanic needs to install it. thanks for the help

 

Thanks! The EVO is even lighter. The uppipe can be done using step by step, it is a PITA though. Make sure you take the turbo loose when bolting it up and then tighten the uppipe at each end before retightening all the turbo mounts.

David,

Have you seen an RS-R exhaust in person? Could you compare yours to theirs for me, and for everyone else interested. I just purchased their catback based on feedback from users and photos of the exhaust.

Thank you,

MVEOVA

 

Seen too many to keep track of. I can't compare for you. You have the specs on ours, pretty easy to compare from there.

Does anyone know of a site or place I can find pulls done with different exhaust set-ups, just to see what the best set-up would be for the cheapest?

 

I believe that the two cheapest are Buschur and Magnaflow. There might be some others, but these are the cheapest that I have found.

 

Do a search for Dragsport or TPR Magazine on here. They did an exhaust shootout a few months ago. I posted the results, as we won overall, and you should be able to find them pretty easy.

Did it, didn't see any real results, just you saying how your's was good...looked to me like those one's in last place were doing a lot more hp than your's and the other one, cuz your's was what, like 247 or something, and stock is like 230-240 depending on the dyno, and what their's was like 250 something? Just sayin the reason I asked on here instead of doing a search is I wanted numbers listed, you know like they tried at the begining of this thread.
Type of exhaust----
WHP---
Torque---
Weight---
Cost---
and of course they'd all have to be dynoed on the same dyno with no other mods done to the car...maybe I'll try hunting down the article

 

Anybody have a sound bite for the 3" Buschur turbo-back with test pipe? Wondering how loud it is?

 

UT Evo go to tprmag.com, they have dyno plots for the cat-backs from their test.

 

After looking at the whole thing I realized they tested the "Cat Back" applications... So with this being said- it's pretty

 

After looking at the whole thing I realized they tested the "Cat Back" applications... So with this being said- And me purchasing the full turboback system (with cat delete pipe) I realized the power gains out of most all of these exhausts will be very similar.

The B&B system claims an average HP gain of 25HP and maximum of 50HP with the turboback system. What are your gains from your turboback system Buscher?

 

UT EVO,

I think I actually posted the entire thing pretty open minded. There was no "depending on the dyno" in that test, it was all done on the same dyno, same car, same baseline. Not sure what you found or read. I will try and find it and put up a link.

SMP3000, I realize what they claim, but it is not factual. Their catback was one of the lowest power producing systems in this particular test. The car is not going to gain 50 whp with a turboback on a stock car, regardless of who's system it is.

I do not have numbers for our full 3" turbo back. The initial testing we did on our systems we had a mix of 2.5" and 3" pieces on the car as we built them, not an ideal way to test. You'll see all of this if you go to our website and look under Stage 1, the HP is VERY low compared to what you will actually see with Stage 1 on your car. Take a look at the huge jump in power adding Stage 2 on our site. The reason is from the time we went from Stage 1 prototype to Stage 2 production the car had our full 3" exhaust on it and an AFC.

We really need to take the time to do the testing over again.

I found the topic and hit it so it is now at the top of the Engine/Turbo/Drivetrain section. Should be easy to review all the results now.

It is titled "TPR Magazine EVO8 Exhaust Shootout"
