Can anyone tell me if there is a catted mid-pipe that I can run with my SLP Loudmouths that won't be crazy loud? I leave for work really early in the morning and I don't want to wake up the whole neighborhood when I start my car.

 

I have the slp catted x-pipe with the lm's. When you first start the car it will be loud until it idles down. Other than that you can keep the sound down reasonably. After you rev it over 2500rpm it gets loud. I tried the pypes o/r x-pipe and it was insanely too loud. Why don't you just leave the stock h-pipe on?

 

even the catted x IMO may possibly still be louder than the stock h pipe....loudmouths are just nice tips lol no mufflers here

 

most all aftermarket midpipes are the same size as stock ones, just keep the stock H and get some headers

 

Grab a set of simple resonators and put them on before the SLPs. May be some cherry bombs.
