I did some searching on the forums but didn't come up with an answer. Should I cut off the muffler and the cat on my 2001 F-250 auto? Any harm in doing this? Will is wake the dead when I fire her off? There is a shop down the road from me that will cut them out and put 5" back for $190.

Any suggestions?

 

Man, that sounds like a lot of money. It wont make it too much louder and you will really like it. Luckily, my truck did not have a cat, but I spent $25 to have my muffler removed.

 

I had the cat and muffler removed over a year ago, The only materials they supplied was four foot piece of 4" pipe, They welded all the joints and painted it with high temp flat black paint. They charged $ 124.00

It did make it louder, and with a wicket wheel, its even louder

 

Your '01 has a cat?
Mine was built 4-01 Auto. trans and no cat.
I thought only the trucks with manual transmissions had cats in '01.
Either way, less restriction is the goal, so you'll be happier.

Score....I'll see what they will charge for just cutting out the muffler and patching in a pipe piece.

 

I cut my muffler out and used a piece of flex exhaust pipe in it's place. Cut the hanger off the muffler and welded to the pipe and hung it back in the original position. Total cost was about 50 bucks for the pipe and the clamps. As far as benefits, cool sound and lower egt. Last summer I had about 3500 lbs in the bed and 5000 lbs in tow and pulling a 5.5% grade for 3 miles the pryo never went over 1100*.

 

Cat or no cat had nothing to do with the transmission, had everything to do with the state in which it was going to be sold and their emissions laws and testing.

My early '99 is a Colorado truck (auto trans) and came with a cat. Cat is still there (well the shell of one at least).
