SLP310013818 Loud Mouth II 2.5" Inlet/Outlet Bullet Type Muffler

You will get cabin drone at higher rpms.

The media could not be loaded.  I’m ok, what I was looking for was a lot of backfire during deceleration and raspiness. But I can say that my 2015 Challenger Scat did have a slight boost in HP. So paired with the quad tips and back muffler delete I’m ok right now. But around fall I’ll be upgrading the entire exhaust.

got a '04 Grand Marquis and plans to turn it into a sleeper but until I take it off the road and start building the motor I went with a mail order custom Mustang tune (shoutout Martin at Mo's Speed Shop!) and a placeholder cheap exhaust until I go for a "real" exhaust. Bought this muffler, a pack of sawzall blades, and a case of beer and it cost me under $100 to sound better than the exhaust videos on YouTube that sold me the SLP.the reviews saying it "only gives a slight rumble" I think the trick is making sure you don't have a resonator after the muffler. I kept all factory piping at first and only welded in this muffler in place of the stock one but it wasn't really much louder than stock. Deleting the resonators after the muffler it went from sounding like a waste of money to being my favorite sounding vehicle I've owned.

My SLP 2's sound AWESOME! I have a 2011 Camaro 2SS and wow they changed the way it sounded for the good. My stock mufflers were extremely quiet and this woke the engine up!The sound is not extremely loud at all, but gives a nice deep tone that I love. There is very little drone in the car which is a huge plus to me as well. I had a friend recommend these mufflers and wow am I happy he did. They are crisp, deep, and powerful sounding without hurting the ears. I paid a muffler shop $100 to weld these in replace of my stock muffler. Extremely Satisfied!

Theses are way bigger in person. I had to return them they wouldn’t work for my Corvette.

been driving around w/o a muffer and tailpipe for 2-1/2 year v8 04 Dodge dakota (old one rusted and fell off) This one installed with ease. Wasn't sure the truck was running at first at the stoplight. Does have a mellow growl to it upon takeoff. Excellent quality I believe. It looks like it goes straight through except for the interior perforations.

Thanks a lot perfect

Replaced a LM2 that got wrecked as a result of a broken pipe bracket. Honestly this one for some reason sounds better. If the other one fails, I will buy again. (Application 2006 GTO)
