i was wondering if the Z has any resonators, some one had posted pix of under the car, either give me the name of that thread or the answer to my question please.
yah, just discovered that myself.the resonators arent restrictive... They have a straight through design. This is the case with 90% of the resonators on the market..
Team Integra said:The method that the resonator uses to decrease noise does not have any adverse effect on performance. Alot of people are mislead into thinking removing the resonator can free up exhaust flow. HyTech Exhaust in Irvine, CA tested their catback with and without a resonator and the dyno showed a difference of 2whp in favor of the resonator.
A tiny taper or lip is hardly going to make a difference. You could always remove some interior pieces or seats and gain more power than removing a resonator. Even a short ram intake would do more.i dont mind it being alittle louder, but the res does restrict flow ever so slightly, about as much as a high flow filter would improve the flow so it balances that out. i have felt the difference with my butt dyno so you really cant tell me otherwise sorry. and that cut away shows me exactly what i know, the pipe tapers in to allow the sleeve to go over the pipe, then multiple holes allow the gasses to exit through them to hit a membrain, that in itself restricts flow. Its not alot but it is what it is.
