I'm going to replace my entire exhaust from the turbo to the muffler including a new high flow cat. My plan is to have a custom cat-back made. Here are my questions: Should I get a 1st Gen DSM GSX downpipe or a 2nd gen DSM GSX downpipe since I'll be having an exhaust shop make the rest? Any recommendations as far as ebay goes? Megan racing, OBX, other? For those that went with a custom cat-back what was your cost? I'm doing 2 1/2 inch.
