Hey (RED10) how long have you had the FM 40 on. If you just got it done and you thing it's loud it will get LOUDER!!!!! and the FM's have NO packing to burn out, it's a trip WATCH.red10 said:Well I got a 40 series Flowmaster, Sounds really cool but it might be just a bit to loud. I got custom from the Engine back (New Y Pipe). Noticed a nice gain. Got Dual exit straight out the back with 3 inch tips. Looks cool. Will post pictures soon.
