Update: In hindsight it would've been much easier to just get the Corsa GT350 specific exhaust: https://amzn.to/35H0p1H I was mislead on buying a GT system but the guys made it work. Avoid the trouble and just get the Corsa. In any case, doing the resonator delete makes a world of a difference! It sounded great before, but now it just breathes so nicely. Pops & cracks a bit more and overall just sounds more raspy. Thanks for watching!
