Just curious if anyone has ever installed an SLP loudmouth muffler on a 99-up 4.8L or 5.3L truck? What does it sound like? Do you guys think it would sound good? just wondering

 

I have never really been a fan of SLP stuff. I have been told it is junk.

 

Id like to hear it on a truck also....ived heard it on a car and it sounds mean as hell.......

 

I believe Illnali had a loud mouth resonator on his old truck, he could probably tell you what it sounds like.

 

He did. I had the SLP loudmouth on my truck with no cats. It really lived up to its name so I sold it to him. It sounded good on his truck because he had cats. So if you get it leave your cats on.

 

was the SLP Loudmouth with no cats Raspy at all?

would they be louder then a flowmaster 40 series. with out cats?

 

it sounds badass with no cats. Yes it'll be louder then a flowmaster. Just dont dumped it, get a tip for it.

 

what about a 4in tip 18-20 in long. with and Xpipe?

hows interior noise

 

I can tell you this-I had loudmouth on my camaro with hookers and off road y and it was raspy but i loved it and sounded mean as hell with my X1 cam!! Never heard on a truck but by the end of this week i will have a similar setup with dual bullet mufflers but the bullets are a lil quieter than the loudmouth is. I personally think it sounds better with bullets-its a deeper throatier sound IMO!!!! Just my.02 worth.

 

is this what they look like? seems close to a bullet. I have heard a few camaro and tz's with them and they sound good with cats but sounded liek a "tractor" with out them, kind of poped and I jsut didn't like the sound JMO.
