First major bolt on!!!

I'm stoked! Finally scraped up enough $$ and ordered the GMMG cat back for the 99 tuesday. Hopefully it'll be in wed-thurs next week and I can put it on next weekend. I have a free pass to a chassis dyno (Thanks HPE!!!) so I'll let all of y'all know if it makes more power or not. I'll be happy with 10 more rwhp/tq. Previous best was 283hp/297tq. ( Yeah, for all you racers out there, I know it's low, but keep in mind this was on a bone stck 99 ls1 a4 with 104,000mi) :iceslolan
I'm almost at the point where I can start making some good upgrades to the 99 and start (again) working on the 91.
Just so excited I can't stand it!!!! I've heard this cat back on a ls1 before, and it was awesome!
