Pacesetter headers are your bang for the buck. Get cats and the borla xr1 muffler to quiet the LM setup. Check my sig for a link to the exhaust clips
Search my name KIRKEVIL on youtube to hear all the different setups I have gone through with the LM 1. Goodluck, its gonna be loud no matter what you do with the SLP LM catback.
