Amen to that! I keep telling people, your going to get 10 HP gains at best with an exhaust, but only with a header and intake as well, but likely only half that. Exhaust is the LAST mod you should consider doing when NA, and is mandatory if you go turbo. So spending upwards of $500 for one is not a smart thing. If I bother with bolt ons for my SE-R, I'm going to get the Pacesetter ceramic coated header and the cat-back exhaust for like $360, and I'll be doing a homemade intake at the same time and possibly UR pullies, although pullies are even worse than exhaust for your power gains to cost comparison, but it's a later step to take when NA or turbo for that matter. I might skip all that crap and do a DET swap right away, that's my long term plan anyways.Originally posted by GundamONE: "But then again if you buy an exhaust you're not looking for power gains, you're looking for sound.

I don't either. On a V8, yeah, it sounds deep and mean, on a 4 banger, it sounds annoying, like some guy with a whimpy weed eater. Intake on a 4 banger sounds nicer than exhaust. I'm so sick of fart cans, that's why I didn't buy the pacesetter cat-back already. I needed a new muffler but I didn't want that fart can muffler that the PS comes with, so I bought an OEM one for $60 and put it on and am done with it for awhile.Originally posted by KdudL: "some people buy the exhaust for sound, which I dont understand why."
Sheeesh! that must be a really rought neighborhood to have someone rip off a exhaust system!glowsentra said:I've seen dyno's of several 4 cylinders my friends own, and on average it has added around 6-7 hp to the car. Bolting it on is not a very good idea though. A Talon had one bolted on and somebody jsut ripped it right off. Better to pay 70 bucks and have it welded on. It'll make the air flow smoother too.
