I have an 04 gmc with the lly engine. Does any know where a dual exhaust system for this truck can be purchased and if it a catback system

Call 1 800 909 7071 and ask for Andrew

MBRP COOL DUALS PUT 3 SETS ON 1 LB7 2 LLY VENDER HERE

The MBRP system sounds pretty sweet and looks good, too. If I were a dual exhaust kind of guy, it'd be on my truck.

MBRP makes one that a lot of folks like. ATS makes one that's more money. I think Banks builds one, but not sure of that since I've never really looked for duals.


I believe no matter who builds it, it comes in a configuration that bolts on to the flange just behind the CAT. Then for people who want the full system, you just get the down pipe that eliminates the CAT.


Some are having problems with eliminating the CAT and having the trucks set codes for insufficient EGR flow and SES lights, some aren't having this problem.


I went with a CAT back single and one of my concerns was that the new system clear my B&W fifth wheel/gooseneck hitch which mounts under the bed between the frame rails. I don't know if duals present a problem with that, or it it's a concern to you, but be sure you ask the question if you're planning on a fiver/gooseneck type hitch for your truck.

goose hitch will present problems with the duals but can be modified to fit. I like the ATS system myself

mckinney,


We sell tons of the MBRP systems in singles and duals, heres a review of them done on this site for you to look at:


MBRP EXHAUST (http://dieselplace.com/forum/forum_posts.asp?TID=11123&PN=1)


They come standard as cat back and you can get the front pipe if you want it as an extra item. Most folks leave the cat in place as it keep sthe system pretty close to stock sound levels, but if you like to hear it it gives you an option etc. Call me and we will be glad to help you with questions etc.
