Just recently bought an 06 mega cab. Bout to go knock off the muffler and cat and i dont have my shop anymore for my DIY stuff. When i had my 96 Cummins it cost about $50 from the local shop but that was a few years ago. What would be an acceptable price range?

 

Call and find out shop rates. But don't expect them to do the cat. Illegal for them to remove it permanetly.

 

i took my muffler off and put a piece of flexpipe in its place and it cost me like 40 bucks for teh pipe and clamps combined. its not hard you can do it in your driveway or where ever just get a saw-zall cut the muffler and cat out and put flexpipe in aint that hard to do

 

Know where I could find some flex pipe? Local auto parts store carry it?

 

napa has 4'' flex pipe or a truck shop. the 04-07 5.9l don't sound good with a 4'' straight pipe. they are loud as he!! in the cab

 

go to like a big truck shop they would have it and everything you would need like clamps and such. the flex pipe on mine sounds good i think but i still have my cat till my tbe exhaust comes. the only time its loud is when you go trough an under pass or somethin. it works for a temp. fix till you get some coin for a real exhaust

 

Agreed. Heck of a drone. I put a high flow back on. It's tolerable now.

 

Appreciate all the input guys, thanks.

 

i would cut the muffler off and leave cat on the sound good that way or put a high flow muffler on it.

 

my 04.5 5.9 sounded great with strait pipe.....i took muffler off first and left resonator on...it sounded good, but after i took the resonator off, i loved it!! on a good clear crisp nite, u could hear it 8 miles away!!!
