So I bought a slp loudmouth axle-back system and I was wondering if I need to do another tune on this? And if so...are there any walkthroughs on modifying a current tune? Thanks all!

No you don't.

No you don't.


+1 no tiune required

+2. As far as I know, no tune is required for any axle-back

okay thats awesome! do you guys know if this adds any hp or torque?

No it doesn't. Maybe 1.

Nope but it'll add A LOT of sound!!!

The OEM stock mufflers are pretty free flowing and unrestrictive to begin with... figure negligible HP gains... however it will ADD a smile to your face,:D that's for sure.

+3. NO TUNE Or INCREASED HP. DID PUT A SMILE ON MY FACE. FRPP STINGERS.

okay so it did put a smile on my face...started it up and it set of my other car's alarm...its pretty bad ass!, but the only issue i had was the brackets didnt line up for some reason...probably gotta do some fabrication...

Glad you like 'em ... Just play with the hangers and loosen the midpipe a little until you get them all lined up.

Yea loosen the hangers and the midpipe, align the tips then tighten everything up and you'll be in business!.
Rshamekh- I like that new pic, looks great

so essentially loosen the midpipe. raise it up and bolt in the loudmouths and then the midpipe when done?

You want to loosen the muffler hangers, then the midpipe, align the tips, tighten the muffler hangers and lastly tighten the midpipe back up. By loosening the midpipe you'll be able to get them near perfect.
