does any one have a custom setup running on a high flow cat or just a dp how much did run you?
sound clips?
performance?

 

I have both the high flow cat and the downpipe. From there on I had custom 2.5" piping bent with and 18 inch resonator. I dont have and clips but I can tell you and sounds and performs much better than it did. I actually had no exhaust for a full month because I blew my old cat right off the welds. My car was running out of wack then. All in all it cost me about a thousand. But it was more than worth it though too. My turbo spools up much faster and its all flowing much smoother.

 

Yeah, I have techtonics downpipe and high flow cat, it's a noticable difference but nothing amazing.
