yup that's what my truck has! It runs fine but gas mileage sucks! So how much MPG & HP do you think i will gain going to stainless long tubes and 2 high flow cats and magnaflow right out in front of the right rear tire???

 

Quarter million miles.
Don't mess with it. You got a keeper the way it is.

CONGRATULATIONS on yoru reward for taking care of your truck !

MPG sucks maybe because the wear.

 

Well I have a light exhaust leak by the exhaust manifold and its getting on my nerves! Also I'm sure the cats should be some what not flowing good so its time for all new stuff
