i was thinking about getting the greddy sp and header. but within 6 months i should be doing the turbo kit as well. someone told me i should stick with 3" exhaust if turboed. what do you guys think, and can you recommend some good 3" systems.

the sp sounds and looks awesome. if you are getting one, make sure you get the gst piping, as its a little larger.

i would think 2.5" all the way back would be fine for a turbo application.

If you are going turbo definitely get the 3" exhaust. I have the 3" apexi WS and I love it. I prefer the "stock" looking canisters. Here are some pics of it on my car.

will the 3" bolt straight on to the stock cat or will i have to find a 3" test pipe or high flow cat???

that looks good jerseystyle. sort of like my greddy sp, only with bigger piping hehe.

i think you would be fine with 2.5 all the way back. if i was re-doing my exhaust i would go 3 all the way back though.
