SLP loudmouth?
Hi guys, I just recently got a 85 iroc-z it has a carbed and cammed 350 motor in it. MY question is has anyone ran the slp loudmouth? my 96 mustang GT had it and sounded amazing. I know i could run the one slp resonator then go over the axle with tips. Anyone have videos or thoughts on it?

Search on YouTube. I found several on there while researching the sound of a true dual lm1 setup.
Stay clear of the lm2. They neck down inside the muffler

They sound best on stock manifolds and definitely with cats.

Sounds pretty good at idle and WOT
Mid range, esp highway is an annoying drone
Much better sound is using the LM1/2 catback with a powerstick welded in place of the resonator
