welp as im still waiting for my LT's and ORY i was wondering if anyone know how loud or if it will hopefully sound good with the slp LM1 exhaust. Just looking to see if i might hafta change mufflers etc. I just dont want it to sound like butt. Thanks

 

Well, you don't really have a muffler with that setup, just a resonator at the tail end of the system. Check out the video section on www.lt1engine.com and the sound clips on www.ls1sounds.com for a reference of what you are looking for.

Should be plenty loud if that's what you're looking for

 

It will be loud, rest assured. It's also gonna clear up alot of raspiness you have with your LM1.
