  SLP Loudmouth Axle Backs

  For the price this will definitely not disappoint you. There is a little drone but overall it’s worth it specially if you know your getting into modifying your car.

  Sweet!!!

  Love them! Totally changed the sound of my car. A nice deep rumble with a lot of popping and cracking on deccellaration. They sound great. I recommend.

  Minor Fitment issue

  I recently installed these on my 2005 GT and they sound amazing. There was a small fitment issue that involved needing to grind 1/32 of an inch of the passenger side mid pipe. (Only added 15 minutes) other then that it was an easy install. And my mustang finally sounds mean and aggressive :)

  Sounds and looks good,not too loud

  install was super easy. i have a bunch of bolt ons and long tube headers. These sound great,great tone. I thought they would have been a bit louder tho.

  Violent

  I'm running this exhaust paired with an offroad x pipe and it is about as loud as you could imagine. Me personally, I love it, but if you aren't prepared for some rasp and an ear piercing exhaust note its not the one for you. Sounds like a NASCAR when you are at WOT.

  slp exhaust

  The product looks good , installation was simple on the passenger side ,the drivers side was not as easy.The exhaust hanger rod would not line up with the factory exhaust hanger.I had to modify the hanger to make it work.Thank goodness I had a hoist.Once installed,it looks and sounds great.

  Great Looks and Sound

  My GT was missing the factory mufflers and exhaust tips when I bought it. It sounded great but was missing the tips. These eliminated the highway drone that I disliked by running the exhaust back out the back. They look great. They are aggressive when you give it the beans and moderate otherwise. Cold starts are aggressive. Most satisfying add on I have bought. Really great sound even with an otherwise stock exhaust.

  Too Loud/Raspy

  This exhaust was a cheap fix to a problem when I bought the car. This exhaust was fun to play around with and you were almost always the loudest car on the road. The note is far too tingy and raspy when combined with my O/R X-pipe. Was way ready to get to a better more pretty sounding car that I didn't feel bad starting at night.

  Style and Class

  The SLP Loudmouth axle-back exhaust is AMAZING! My car was kind of obnoxious with just straight pipes, but with the SLP Loudmouth pipes it still has an AMAZING sound but not is not obnoxious and it actually has a cleaner and more distinguished sound.

  Install was easy, as I have a lift. Alignment was fairly easy, just don't tighten anything until perfectly satisfied. Fit and finish was great, and they sound awesome!

  Amazing sound

  Added a growl to the already good sounding engine. The perfect axle-back exhaust as long as you don’t mind a little drone

  Sounds Nice, Easy Install

  If you watch youtube videos to reference the exhaust note, it's exactly what I wanted. Takes about 30 minutes to remove the old and install the new. No issues on fitment, and straightforward installation.

  Loudmouth is an understatement

  Buyer beware. These may be "loud" on a mildly modded car, but with a cam, LT headers, and a catted xpipe, they're downright obnoxious! And I love it. Cold start, they rumble and spit. After warming up...they calm down, until you mash the pedal. Pretty easy to scare the pants off the driver next to you on the highway. Not much drone, and actually pretty docile at cruising speed. Buy the hangar kit. I didnt, but will order today. Fit is just a tad off with the kooks xpipe. All in all, I love it. My wife....not so much.
