I have been trying to find an exhaust for my 2010 crew cab with the 6.2. It seems like no one makes a cat back in the 3.5" factory size. Only 3" stuff. I would just replace the muffed but some one before me did a half *** setup with dual pipes so I can solace just the muffler.

I want to do a Corsa setup and I see where they make 3.5" setup for the 2014 trucks but only a 3" for everything else. Just wondering how much different the 2014 are. I figured hangers will prob be different which is no big deal. I can cut and do fab work to move them. I just dont want to have to cut everything up to make it fit. If I have to do that I will just buy some bends and tube a build it from scratch.

Too bad Corsa won't sell just a muffler.

 

Magnaflow and Borla also offer a 3.5" system and will both sell muffler only.

 

Throw a 3.5 Magnaflow in place of the stock muffler and go with it.

 

I think that's the plan with my wife's truck with the 6.2.

My 6.2 on the other hand was cut off from the last guy and they did a poor job of making duals with a 40 series flowmaster. It's too loud for me and I don't care for the dual pipes. That's why I was looking for a full catback setup.
