No More Mufflers - Easy/Cheap Exhaust Mod

Anyone else done this? Went to my muffler shop and had plenty of options...Had to cut the mufflers off to do anything, so we started it to check the "raw" sound. It was still fairly quiet! Great rumble and anything but obnoxious. Only a very slight drone when cruising at 65 at 2K RPM - not bad at all, though. Sounds wicked cool at WOT. Easy and cheap! This pic is from my phone - sorry. Oh yeah, saved a good 30+ pounds as well.

Are you still happy with the result? I haven't done any long distance driving yet - am just a little concerned about the drone...Thanks.

If you like it - cool

I have yet to hear any street vehicle that sounded good w/o any mufflers.

might sound a little different but you wont gain any performance,, if you cut one of the stock mufflers apart you will see it is a straight pipe through the muffler inside with a bunch of fiberglass packing material

What's the difference between this and the SLP Loudmouth exhaust that Selena installed?

Looks like the mufflers are still there....are you referring to the resonators?

its not a straight pipe, there are holes all alround the pipe that lets the exhaust go into the can.

the slp loudmouth is just a muffler delete as well.

dyno #s prove that this makes more power.
