LoL... I like semi-quiet exhaust! Can't stand loud, obnoxious, raspy tones and the cat-backs for the GTO are in the stupid price range... I prefer to go custom 3" when/If I do a cat-back... which I probably will now whereas I am in the HP range where it will affect the results.....Obviously!
The 10hp gain before wasn't worth the $800 to me for a couple pipes and mufflers.... know what mean...
But at least the car will still pass emmissions next year when it's do with the SD tuning!

Matt I wish.. but I will eventually have to upgrade to a one-piece drive shaft and as the car sits now with tiny 2.25/2.5" piping it would already interfere. I think a custom 3" with sweet thunder mufflers will be a good choice, hopefully with the sound of the GMMG I had on my Trans Am!

You mean when he dumps it... he gains 60-80rwhp? If that's the case, then it'll be a must to get something on there soon....... DOH
I have done some research on SD...it seems the way to fly. Still scratching my head with EFIlive, but I am getting it, just slowly. If I get everything I need, do you have time to do the re-tune? The car runs ok, but is kinda rich, and right when it starts to boost, it lags for a sec. I will probably see you dyno day anyway.
