SLP LoudMouth to LoudMouth II???

Post by 2000 Red Hawk » Mon Jun 20, 2011 8:43 pm

I purchased a SLP LoudMouth Conversion Kit from Jegs to go to a little quieter LoudMouth II. Has anyone installed these on their baby? I am having trouble finding anyone that doesn't weld with clothes hangers here in Baton Rouge, LA. No one wants to mess with the Stainless Steel pipes. I have pictures.

Thanks for the help in advance!

You have a Loudmouth 2 on your car now and you are going to swap that out for a Loudmouth 1 to go quieter?? If thats your plan then scrap it and send back the LM1. The Loud mouth 2 is suppose to be quieter then the Loudmouth 1. To get your loudmouth quieter you either need to get a SLP power flo conversion kit, Get a Dynomaxx or borla resonator and weld that in place of the Loudmouth one, or just get a new catback all together..

If I remember right, the LM1 and LM2 only diffrence is the resonator iteself which should be band clamped in, not welded.

Honestly though, the LM2 is not much quieter and still has a ton of drown especially with a 6speed car.

I'd send back the kit, sell the LM1 and buy a GMMG from Vengance racing while you still can.
