I have a new IX SE. I have already purchased an O2 housing, 3" downpipe, and test pipe. I was wondering if there have been any dyno tests or links to articles done to see which cat back exhausts make the most whp. I have done many searches, but most of them relate to the quietest, not the most powerful. I would really appreciate any input on this subject.

Thanks

 

I guess most everyone related HP gains to a full turbo-back setup. Youl see some minimal gains from a catback..id say most of em will give you close to the same with different pitches in sound. Choosing the complete turboback will net a huge gain when tuned.

 

From what Ive seen and researched, Buscher Racing has the turbo-back exhaust with the biggest HP gain. Im not sure of the number but its sais that they have the best exhaust for HP gain. Im not too found of the pitch myself so I pieced my own together and I like it a lot, theres a slightly noticable power increae and I love the sound. Nice and quiet at idle and big and deep at WOT.

TTP 3" DP, UR 3" HFC and Espelir 80mm JGT500 cat-back exhaust.

 

Most any 3 Inch pipe is gonna perform the same, maybe a slight HP difference of 1-2 HP at Most. Do your research to see the Straight thru desgins such as Greddy Ti...etc...Stay away from neck downs and sharp degree bends in the piping. There was a thread on here about the infamous "beer can test" do a search for it. It will be enlightening to say the least. It's all about money and the bling factor in some cases. The Megan exhaust is great for the Money, the Greddy Ti is great if you want the ultimate weight reduction and staright thru design. But if you are running a test pipe be prepared for an increase in noise...With noise comes power...haha...Congrats on your new purchase of an Evo.....enjoy it but learn the ins and outs first...don't go backwards when modding, do your research, set goals, get what You want...out of your Evo..

 

RSR EXHAUST, straight 3 inch from the cat and only one bend where it goes from rear axle out the side.

 

Thanks everyone.

 

I think the ebay exhaust is one of the best 3" exhausts out there

 

Which ebay exhaust are you talking about? Do you have it?

 

The Ebay exhaust was tested by Buschur Racing when a customer came in. After they got the car tuned with the Ebay exhaust, they slapped on the Buschur Racing Turboback exhaust and the car gained lke 20awhp!!!!! I was like holy ****!!! Thats one of the reasons I own the BR 3" Turbaback....

 

BR TBE I have a video clip of it with a test pipe and bullet muffler option in my sig

 

buschur!!!!!!!!!!!!!!

 

How is the AMS TBE?

 

Since I already have a Perrin 3" downpipe, and UR testpipe, would getting the buschur cat back still give the same hp gain as the BR full TBE?
