hey man, i had a screw up from jegs and they sent me mufflers that didnt match, one was offset/offset, the other was offset/center so i had to order another one, but i already had my O/R H pipe on so i ran around for a week with no mufflers and no cats. its loud but it is ungodly loud, and gets on your nerves, id recommend cutouts, QTP electric cut outs. and run a muffler like the borla S types (the stinger mufflers) behind it. but trust me a LM is nearly like no mufflers and its cool at first but then its annoying. id recommend cut outs heavily.
