Not much if you're just intake and exhaust. Starts to matter if you're FI. . .

I think on a non-FI setup you're better off with the stock cats for back pressure.

I know I brought it up at one point in the past! Just didn't have the money/balls to give it a shot. Glad it worked for you, now I can't wait to try! Nice job.

Thanks for the reply, I was thinking the stock cats are the biggest source of back pressure so just sticking them on the end of the headers is great for passing emissions but the bottleneck is still there no?
