Just curious who out there has put on an aftermarket exhaust system and if so what kind, how much, did you do it yourself, did it improve gas mileage? I had a flow master cat back on my 01 ram truck and it sounded cool but did little for gas mileage.

 

I have a Magnaflow with JBA exhaust headers along with ported cylinder heads and the change is night to day. I have a Magnaflow cat back sytem for sale if you are interested,

Interested, How much? and where are you located.

 

I am in Pittsburgh. What year is your Durango? It is new and never was used ans will sell it for $400.00 and I will throw in a Jet Performance chip for free:

Its an 06 durango limited with the 5.7 hemi. I live in Mariposa California.

 

Mine will not fit your 2006. According to their website, they are different sizes between the 2006 and 2007 (5.7L) exhaust systems,

I put the Flowmaster American Thunder Catback system on mine if you like the 70's hot rod sound this is it Duals from the cat back ( I don't see why no one came out with true dual exhaust for the 04 as it has twin cats in the y pipe and can be cut before they join)
