Gms1
new kit for 435 here USD https://www.cobaltss.net/forums/part...-cover-241500/
I have a cousin and friend go trifecta, I went GMS1. Best of luck to you, hope you have no warranty-voiding issues.
welcome, I have a drop in also. Was talking about getting a catless DP and catback exhaust (3inch) which is my recommendation if you're going trifecta. it really does wake up the car with the dual cat-converters gone. My cousin had a stock 2010 SS TC with trifecta, then went catless and he saw noticeable power gains and difference in driving his car. "A whole other level" his words not mine.
