Meh ya it is kind of loud but its nice i like it a lot. Guess some people just need to grow some balls and put up with it. Over here in il we dont get bugged for loud exhaust unless your in chicago...

WARNING to all thinking of installing an off road pipe with SLP Loudmouth a xle back exaust ! DO NOT DO IT!!!! IT IS WAY, WAY, WAY, WAY TOO LOUD!!!!!! !!! IT SOUNDS AS BAD AS A BUSTED MUFFLER AND IS LOUDER THAN ANYTING YOU HA VE EVER LISTED TO ON THE ROAD OR OFF. I wasted $500.00 between parts MIL eleminators and labor. Just want to save anyone else the trouble!

I have an 06 GT with SPL LM's and just installed a Pypes off road H-pipe at Haywood Custom Speed. No cats and no mufflers. It is way, way, way too lo ud. I am re-installing my stock H-pipe ASAP! Already came very close to be ing pulled four times in one day. IT IS INSANELY LOUD!!!!! WORD OF ADVICE, DO NOT EVER DO THIS WITH SLP LOUDMOUTH AXLE BACK EXAUST!!!!!!!!!
