Good quality for a great price

I used this on my diesel tuck just to mellow the rasp out a little bit. It did that and gave it a deeper tone over just being straight piped, but didn't sacrifice the overall sound. If you plan on welding this in take the extra time to clean the ends since there is an oily residue on the metal.

Pros

Put it on my lb7 duramax and sounds great. Love it!!!

Cons

The muffler can cause damage to the exhaust pipes
