You need to give us some help. Do you currently have an ls engine in the car? How much exhaust do you need, headers and pipes or just pipes? Are upgrading or is this your first system?
I'll start. Look at the hooker blackheart system from holley. Arguably the best system. High quality, do it your self, bolt in system. Yes it is expensive but the fit and finish is top notch. This is what I'm using on my swap.
Are there others out there, possibly. I hope others will speak up.
