I have a 1LE with NPP and already pulled the fuse but I still want it a little louder. Suggestions? Which headers work best? Anyone know of a shop in Cleveland, OH area for install? thanks.
May want to consider what I have. Hedman shortys, Solo HF Cats, CAI and QTP remote controlled cutouts that can be opened incrementally. I also have a Dashlogic unit so I can run the NPP stock, always open or always closed. With cutouts closed and NPP closed (very nice and good for the neighborhood and LE); with NPP open (yea buddy pure muscle sound almost sounds cammed); with NPP open and cutouts open ...pure badass
and at WOT I've had people say it scary
Oh yea none of this voids the warranty.
