Recommendtation, don't add headers until the LM is off or you may not have your hearing anymore

 

pfff - i run loudmouth with headers and no cats- i hear fine just the people behind me that dont

 

same here, I have pacesetter LTs and ORY with the LM, and I have no problems, I love the sound of it in the upper rpms. It also sounds great when your coming off the throttle and downshifting and it cackles a little bit.

 

Same set up here and I love it to.

 

Crazy. I had mid lengths, LM with a cat on my old LT1 and the drone was unbearable.

 

Thanks guys I love the way it sounds. its sitting at my buddies house right now waiting for the shift kits to be put in, and he wont tell me what else he is going to do. But he says he thinks when hes done it will run 12.8 or so, I guess i'll have to go to the track and find out
