slp loudmouth II muffler

[derek33 10+ year member]

does anyone have experience with slp performance. Im looking to get the loudmouth II muffler for my 5.2 grand cherokee.

Im currently running no muffler at all, and i love the sound and loudness, but i do need some backpressure for my jeep to run properly, so im looking for a loud muffler that will provide some back pressure.

thanks

SLP did all the firehawks for GM, and they are a major Chevy parts dealer.

SLP is good parts man, dont worry about them.

i hear great things about SLP, my buddy has the original loudmouth system on a gtp and it sounds nice, for a 6cyl that is //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

my friend has the catback on his 04 mustang mach1, it sounds like a nascar.

(it's full exhaust tho - custom hooker headers, bassani offroad x-pipe then the loudmouths)
