I have a 07 classic 3500 4x4 gas dually(cab and chassis). Rear frame appears to be pretty narrow compared to my 1500. The Y-pipe got ripped off of it and is too mangled to repair. Will the exhaust from a regular 2500 fit this truck? I'm not really wanting to do headers for this truck, but if that's my best option I'll go for it. Going to be just a weekend tow rig and might see a few grocery store runs...NO RACING.

 

Several companies sell cat back exhaust. What Engine does it have, the 6.0 or the 8.1L?

 

I'd just take it to an exhaust shop and have them replace whats missing.

 

It's a 6.0L with 4L80E.

 

The exhaust from a 2500 should fit.

I know Mangnaflow has a kit and I think there are a few other companies that had kits.
