Quieting down a loud PV muffler?

6 to 8 inches of perferation of the same size as the tailpipe should do the trick. If you go bigger, chances are you will aggravate the problem and much smaller seems to produce a sound similar to a cornered cat.

Thanks for the reply, John. So, it sounds like I should get this 3"x12" baffled tailpipe PLUS a 6-8" perforated resonator to put inline between the PV and the engine? The inline resonator should go BEFORE the PV, right?

I figure I might as well as go the extra mile and as long as they're going to be hacking the exhaust system apart to put on the dual tailpipes. Couldn't hurt to put on a noise suppressor tailpipe in addition to an inline resonator... right?





I know what you mean about every car being different depending on pipe length and other factors. You know that sound you get when you blow into an empty beer bottle? That's EXACTLY the way the inside of my cabin sounds at around 1,500 - 1,800 RPM. If I could at least get rid of that beer-bottle resonation effect, I'd be a much happier camper.
