Default anyone else got an slp installed?

I just bought one ha..i remember seeing a vid of a monte ss with one and loved the sound..magnaflow sounds nice but is too quiet..from my experience flowmasters always never really caught my eye so I got the slp..cheaper sounds good and is louder..im just wondering if anyones got one installed and if they happen to have any videos of it...i already got a hogan downpipe to pmpliment it - next is a hiflo cat and intake ha..im in predeployment training now so I can't even see my monte til my leave on late august ha but anyways if anyones got any vids or any words on the slp lemme know thanks!

I have it on mine, but I do not have mufflers!! And the SLP cat back exback WILL fit with NO PROBLEMS. It comes with a extra "hanger adapter" that bolts up to the frame no drilling and thats it, so everything's just purely bolt on!! ... I think I would pick these anyday over the quiet resy-equipped magnaflow exhaust system....

Pre Deployment.. nice! I've got a little brother in the USMC stationed at Camp Pendleton, doing logistics for the USAF right now. He was loading ships. I'm in the Aren't ready MARINES yet branch (ARMY) lol.
Best of luck to you and your comrades!

Not a lot of LS4 owners have gone with this kit so I'm interested to hear how you like it. I have heard that makes gobs of torque, so be prepared!

SLP LM exhausts are usually straight pipe with small resnoators

my thoughts exactly. if anything buy an slp loudmouth resonator in your diameter and it should sound very similar.

so hold up the cat-back exhaust for the 2000-2008 monte/ss will fit the 2008 impala ss with just mounting an extra hanger, everything else just bolts right up?

ok guys, no more flow 44's. SLP it is! got the lodmouth 2 resonator installed yesterday morning. i have no muffles and the resonator went in right behind the cat! First start up.....very low rumble...instead of the flowmaster high pitch gargle. rev: deep,loud, with some rasp which sounds good to me. i would NEVER go with flowmaster again! the differernce between the lm1 and the lm2 is that the lm2 has material packed inside and the lm1 is straight through with nothing inside. Both resonators are straight through design. i love it! still have to break it in...
