Anyone running 2.5 inch exhaust without muffler
Monday, August 07, 2006 7:24 AM
I was just curious if anyone is running a turbocharged car without a muffler. I'm wondering if just using a converter with a resonator (like a cherry bomb) would be too loud, or if the turbo would keep it quiet.

running mufflerless will do nothing but make your car loud.

id suggest running a nice high flow "turbo" muffler from autozone for liek 20 bucks, flows well and costs 20 bucks.

i however run on my integra, a 3 inch dp, to a 3 inch straight section of pipe, with 2 24 inch resonators run inline with eachother and no muffler, with a turned down tip at the rear axle.

its really not to bad when your out of boost and not ripping it, but when you get on it its dumb loud.

also it drones on the highway.
