Default Slp Loud Mouth

How are you guys running the SLP Loud Mouth exhaust systems liking them? I'm thinking of swapn my Magnaflow to the Loud Mouth because the Magnaflow for whatever reason doesn't fit or line up as well as I want it to. I want something with more sound as well.

Depends on how much sound you want, I have the SLP loudmouth 2 and it gives you a great Vintage muscle car sound, it sounds good especially wide open. I've heard the LM 1 is a little louder though.

The LM1 is super loud. But i have LTs and the ORY. I decided it was a lil to loud after 4 years, so i cut off the slp "resonator" and had a buddy of mine weld in a borla xr1. I think it sounds awesome now!

Well i did some research before i bought my exhaust. I heard Loudmouth too much poping and rasp. And Flowmaster Sucked. So i got Magnaflow.

Few LT1s on here.

I would love to take that magnaflow off your hands. I had a LM2 and didn't like it as much as my custom 3 in with a flowmaster.

Why didn't you like the LM2..I was under the impression a lot of guys on here ran these and loved them?? If I do swap you got first dibs. It's in great condition and has prob 4k on it.

I have basically a LM 2 here (TSP Rumbler, 18" bullet) and I think the sound is great, just wish it had a little more bump (Still have a cat with the midlengths, LTs coming soon). But the TSP with a cat STILL gets many compliments, to which I always reply "it could be better"

Used to have a LM1 on here before I bought it, and that sounded pretty good too.... It pops and rasps sometimes, but if your going for a more "nascarish" sound this is for you. And when you add LTs, honestly nascar and that would be pretty much the same

I have an SLP LM1. IMO its a good stand alone exhaust, but if you get LT Headers, its a bit too loud after. The SLP LM2 however isnt as loud, but it has a deeper tone to it... and is a good free flowing exhaust still.

The GMMG is still my favorite exhaust hands down, its just a bit too pricey lol. But if you can get an SLP LM2 for cheap, go for it, even its just a temp exhaust. Thats what my SLP LM1 is until I get sick of it lol.

That does sound good!^^^^^^^ Im happy with my B&B tri-flo It has areally deep tone all polished muff, tail pipes, and tips. Lingenfelter is the only place i found that sells them and they go for around 850. Only thing I would replace it(maybe) for is a borla, true duals or that GMMG.
