KikoSanchez182 03-31-2002, 01:42 AM what size should i get for a fully bolted on car? im thinkin 3", or do you guys think thats a bit big? please post pics of cars with 3" if anybody has it. also, what can you tell me of the pacesetter header vs hotshot header? autoxer7 03-31-2002, 03:11 AM Conventional wisdom in the SE-R community says to go no bigger than 2.25 inches for a bolt on NA sr20de. A 3 inch exhaust is what a lot of the turbo guys use.

Brock Stepan 03-31-2002, 03:18 PM Go with the Courtesy cat-back in 2.25 or 2.5 in. diameter. I have the 2.5 in diameter with a few bolt-ons and I LOVE it. The sound is bad-ass! KikoSanchez182 03-31-2002, 07:53 PM so should i still get all the piping even if im stayin with the 2.5" b/c of the resonator in the piping? aztecred92 04-01-2002, 01:11 AM Bill Luton, president of Izuzuperformance.com, wrote to Sport Compact Car magazine (May 2002) to disagree with a generalization that Mike Kojima made in his Nov. 2001 article, "Build your own exhaust". According to his research, 1.5 to 2.5 liter N/A cars could benefit from a 2.5 exhaust. KikoSanchez182 04-01-2002, 09:19 PM yup, thats what made me think of this thread Its311Pete 04-01-2002, 10:41 PM After aquiring a hole in my stock exhaust system I went with 2.25 I felt a little loss in power on bottom end MY track times stayed consistant. If I was to do it all over again I would go with 2" Madrel bent. Peanuthead 04-01-2002, 11:07 PM How big is our stock exhaust? Is that in I.D. or O.D.? Fosters 04-02-2002, 04:26 PM Something I didn't see mentioned, is if the exhaust piping will be mandrel bent or not. I don't know for sure, but 2.25" mandrel bent system will probably flow better than a 3" crush bent system. Someone else can probably answer that, but I would think that a 2.5" mandrel bent system would probably be adequate for a N/A car. That way you shouldn't run into clearance issues w/ a 3".
