I`m not sure if you can get a muffler that will fit perfectly.

Any exhaust shop should be able to make it fit by either cutting or adding pipe to make it work.

I just purchased and installed the flowmaster #530513 in my 03 Denali. It's dual in single out. My stock muffler was dual in dual out but FM sends you an adapter pipe to replace the dual out with the single out. You will need to ad more pipe before muffler due to it be shorter than stock.

So the piece needed comes with the #530513 ???

Thank you!

I also did the "swiss cheese mod" and threw in a k&n filter and I think it sounds awesome. Cheaper than a CAI if your looking to save a lil coin.
