Quietest Possible Fox/Coyote Mufflers

I've been really surprised by how quiet my set up is, at least until you get on it. I'm running magnaflow 14239 mufflers, and otherwise have 1 7/8" kooks headers with 3" collectors, custom 3" H pipe, and 3" cat back with 3" tailpipes out the back. Cruising under 2000 rpm sounds nearly stock; I hear some rear axle whine and tire/road noise, and not much engine. Romp on it above 2500-3000 rpm, and the engine noise level picks up considerably....

On my old Maverick I tried flowmasters...couple different kinds actually. 40 series were loud. I think the other set was maybe a 50 series? Was supposed to be 3 chamber and a lot quieter...and it was, but still was too loud for my taste. I like quiet. I built an X pipe for it which helped considerably compared to the straight duals and dumps. Then I found a pair of dynomax super turbo mufflers that would fit, welded those in. They sounded GREAT. Quiet at idle, full throttle you could hear it but it was nowhere near attention getting. I liked the "throaty" sound when on the throttle a lot better than Flowmasters...even though flowmasters do sound good, just too loud even the "quiet" ones. At idle the turbos are really nice. Barely hear them in the car with the radio off.

go with dynomax...pretty quiet but have nice rumble.

flowmasters 3 chamber mufflers lol you wont hear a thing

don't the turbo mufflers have fiberglass fill that eventually burns out and gets louder?

I've had dynomax super turbos on my basically stock 90 for a long time now and I would say that is true. They aren't particularly loud but I do remember when first installed they were very quiet - seemed no different then stock.

One thing I do not like is that they seem the loudest (drone,etc) in the 2K RPM Range.

dynomax ultra flows
