Mid pipes, high flow cats
Ok, After i get headers for my GTS, what should I do next? Is a high flow cat worth it? Does a midpipe replace a cat.convtr.? What are downpipes and mid pipes? Any brands out there or do shops have to fabricate these? VERY curious. Please note, that I am trying to keep my car street legal (emissions), yet as fast as possible. I need some serious education in these departments. Thanks!!!! wtf

Downpipe is the pipe that goes from the header to the cat. If you want an aftermarket one, I suggest getting it custom made. The only one I know of is AMSS, and they are not a reliable source.

Midpipe is the pipe from the cat to the muffler. No company makes a mid pipe, so it must be custom made. I suggest you get a high flow cat and eliminate the resonator, but thats your choice. I just got a custom mid pipe, here is the link. Check it out.

Hope I helped.

Haven't gotten them yet. I heard to stay away from Ceramic coated headers. I want TRD or TRIAL, but I'm not forkin' over 800 bucks plus install for those. Hell no. We need a frickin' group buy or something. Anybody know of a good brand of headers out there other than these two?!?!?! confused confused confused
