TTA 591 Exhaust, Finally Done!!!!

Well, I finally had my exhaust done today & it turned out great. I waited over a year to do it, witch is way to long for me, but that gave me a chance to go a different route than most other people. It took time researching & hunting down the muffler & tips I wanted & the exhaust shop to do it. My plan was larger diameter high flow exhaust that was stock appearing. The kicker is having a nice throughty V8 rumble as V6's in general can get raspy & sound like and angry bee. It seems like everyone has Flowmaster/ Magnaflow/ Hooker,etc. I just wanted to stand out & take a little risk & I think it paid off. Here's what it got: Cat-delete, from the cat area back, custom 3" inch into a Corsa stainless steel cross-flow muffler
3' inlet/ dual 3" outlets. 3' tail pipes were made & I used factory appearing 3" tips from Stainless Steel Works.

I was a little nervous, not knowing what it was going to sound like, but to my knowledge, I think I'm the first one to attempt using a Corsa muffler on a TTA or a 3.8L Turbo Buick engine.( I watched alot of exhaust/ sound videos) This Corsa muffler can only be bought with there entire cat back stainless steel systems witch are like $1200+ and are not available separately. (I tried) I got lucky buying this one from someone who was keeping there stainless pipes but going a different route on their muffler & I was at the right place at the right time. Its in like new condition in/out, the guy said there was less than a 1k miles on it & it shows.

I maid a couple videos before with stock exhaust, after with Corsa exhaust and a ride along with the new Corsa exhaust. I posted them on youtube, hopefully they come out good as I never took or posted videos before.( My voice sounds different on video, kinda weird) Let me know what you guys think, Thanks!!!! ttarider

Oh man I love the ride along videos!!! I miss driving my tta so much and it's only been winter for a month here. That corsa sure does sound good!!
 
The ride along video was great-could tell you were having a good time getting on the pedal! Will have to watch this again soon when I am snowed in and need a turbo fix. lol Good choice on the exhaust.
 
wow sounds damn good! I love the difference in sound. I always wondered what to do if I had to change the exhaust and that would be it! Hopefully you can haul it out to the TTA reunion in Ohio next year and I can hear it in person! :) I would get some high heat silver silicone exhaust paint and go around and shoot all those welds and brackets now. It will make them last longer and look good under there. It's almost the color of the pipes so you won't even notice it!
 
Thanks everyone, I'm very pleased on how it turned out. I love the way it sounds. I'm one of those guys, who listens to their exhaust note rather than the radio when cruising, its like music to my ears... Maybe as a future project, I can have the exhaust "Jet-Hot" coated (minus the tips). I have Jet-Hot coated exhaust on my DeLorean & it looks great...I'm going to try to make it to the reunion next year, just can't commit to it just yet, with a new job and all..

I kept the original exhaust, wrapped up the original tips & put it all in the attic. On the original GM muffler, the exterior looked decent, but looking inside with a flashlight, in was deteriorating. I never would of thought that from the way it looked on the exterior.

The turbo spools up a lot faster now, were as before there was more lag time. I didn't think it would be that big of a difference since the cat was already off, but it made a huge difference. I also noticed the engine running a little cooler, from the temp gauge. I might do another ride along video, that was fun...Thanks again everyone for the positive feedback!!!!
