My neighbor has one on his LB7 Duramax and it sounds pretty boss. Never heard one in person on a gas truck, though.

Not like that counts...

AT4040XL


Looking in at muffler (outlet)


Looking in at resonator (inlet)


Height


Inlet/outlet size




I picked this muffler up off Ebay from Atom Exhaust. Great Seller, lowest prices, Free Shipping and awesome customer service


Now the hardest part is looking at them everyday and not being able to install them.

Well I have a pretty free flowing muffler in place of the stock one now and it's dumped under the bed. My plans are to get ARH with an ORY and then replace the muffler I have with a Borla XR-1....or maybe what you just went with once I hear how yours sounds.


It's going to stay how it is for a few months I imagine though till I got some money to blow

Thanks for posting the pics/sound clips.

It does sound good, wonder if it has any rasp?, hard to tell.

In for a sound clip when ya get it on, good luck !

Also its a shame all that nice polished stuff is going to be Under the truck
