I had the catless x-pipe/ slp lm1 with stock manifolds set up and loved it, but I live in Kalifornia and the gayness of my state prevented me from keeping it. Had to have slp high flow cats welded in so when I get pulled over I can at least say I had cats (still loud as F).
Screw what everyone says SLP LM1's are sick.
Favorite part of that set up was when you passed someone you know that not only did you blow their ear drums out you scared the **** out of them.
Keep it LOUD! :rockon::beer:
Dude that sucks that you have to use the cats :nonono: With my Stingers I am the same way. I tend to scare people with them going by them :beer:
