The TOR's have gone through several changes. The first set of Long TOR's were fully baffled just like the stock pipes just with a shorter baffle. The second set I got are straight through Glass Packs or as the older Hot Rodders probably remember them as Cherry Bombs. They do get quite a bit louder with age. Not too loud but they bark pretty well when I give it a fist full of throttle.
Fist Full of Throttle... wasn't that a Clint Eastwood movie?
