ok im new to exhaust and had a few questions. I have the stock set up now and wanted to run slp long tube headers, slp shorty x pipe and slp loud mouth. i was just wondering if this is a good idea or will it be way too loud. I also have the jlt cai and sct3, will i have to get a new tune? about what rwhp will i get out of that set up. thanks

I've never had the slp loudmouths but hear that they are really loud. You should get another tune.

Really bad idea. I ran that same setup and it doesn't sound good. You need a real muffler on the end. You would absolutely need another tune. I gained 22 rwhp.

I have a exhaust shop and put those mufflers on my 94Gt with off road H pipe and it sounded like straight pipes. I put a set of them on my friends 2004Gt with factory headpipe and it sounds sweet. I put super turbo's on my GT with the off road H pipe and that sounds nice. Hope this helps!

My friend had a similar setup and it was not a good sound. He would rev and it would be fine but coming back down it made this gunshot/rattle sound that just sounded horrible.

SLP LM's are best run without LT's. Otherwise they are freeking LOUD!!!
