I got a 2.5in DC sports exhaust for an Integra off craigslist for 20$ (Score!). Hacked it up. Welded in the muffler and the almost S bend to smooth out the right angles in our otherwise fantastic exhaust system.
Also had to weld on muffler exhaust hangers to pass inspection.
Sounds just slightly ricey n raspy with gutted cats but if you have a real header or still have your cats its quite smooth and nice sounding for a "can" style straight through muffler.
You really don't need a 3 inch pipe for our engines unless they are under more than very mild boost and there was noticeable gains throughout the rpm band from gutted main cats or headers and this exhaust. Lots of torque gained down low and the car launches much nicer. Also noticeable HP gains in the 4000+ rpm range. I would recommend sticking to 2.5-2.75 unless your going forced induction.
Hope this helps!
Also, Im diggin the eyelids. I have some myself but they are black plasti-dip right now cuz I had it on hand and it can be removed easily when I get the real paint. Was the factory paint job difficult to match? and where did you get your paint and clear coat from? I have an 04 ES in ultra pearl red and I cant find the factory paint for a reasonable price anywhere.
