So, Since stage 2, my stock exhaust has held up pretty well. I know if I put a new exhaust on, it will perform better, but is it really necessary? Will it have any long term effects on the stock pipes, cat, muffler, etc? Is it a dramatic improvement going aftermarket?

Thanks

Obviously opening up your exhaust is going to help you. The header/dp are extremely restrictive so just changing those out will help you out big time.

everything you need

I wanna change it out, but if were to do it, I would go with the GMPP for warranty reasons. Its just a big ass chunk of change to do it that way and didn't want to if it wasn't necessary.

well getting a catback going to get you a little power, but the header/dp is where the gains are.

gotcha, thanks
