2008 Sierra All Terrain VortecMax

[dirtdriver11]

I have an 08 Sierra All Terrain with the 6.0l Vortec Max. I am wanting to replace the stock muffler with something a little bit louder. I am wanting to keep all of the factory pipe that is on it. Anybody know what muffler would just weld right in the factory area?  Not sure, but I think it is 3” in and 2.5” out that connects back to a 3” pipe.

All kinds of options out there, Carven MBRP, Magnaflow, Corsa, Borla, Flowmaster...

Sorry, guess I should have said I was looking for part numbers and if anybody knew for sure what size would go right in. A lot of what I have researched is more for running duals and I am wanting to stay with the factory tailpipe.

You may need to do minor modifications or just look for direct fit. I would look at Flowmaster but you have to be certain on the exact inlet size. 2.5", 3", 3.5".

 

Exhaust work is possibly one of the only tasks I just bring in to the shop. Just a simple muffiler swap should not cost that much more then a DYI...

Just about all the aftermarket performance mufflers are going to be much shorter because the stock mufflers is fuggin huge.

 

Just get the correct offset muffer and pick up a 1-2 foot section of straight pipe from the local parts. That is exactly what I did years ago on my Sierra. It's one extra weld, so no biggy.
