Strait Pipe Question

[GreenandClean]

I am wanting to remove my muffler and Cat for the fact of wanting to improve my fuel mileage. Is there any reason that I cant (or shouldn't) just go and get a piece of replacement pipe and exhaust claps and just cut out the muffler and cat and clamp in a the new section of pipe?

The reason not to do that is the complexity of what you will have to do. It would be best to buy a cat delete pipe so that you can switch it out easily.

But you can do the muffler your way.

I am very happy that I got the delete pipes because of how much they benefited my truck.

Thank you very much. Being a poor college kid money is sparse so walking out an buying a whole exhaust kit is really tough. Thank you

i paid an exhaust shop to cut out my muffler and weld in a piece of pipe for 40 bucks and bought the cat delete. the muffler is the first piece I would delete

yea start with the muffler

the factory muffler is a hunk of junk it has to be the most restrictive thing on the truck from the factory

I removed my entire exhaust and ran a 4 inch downpipe into four inch MRBP straight pipe. Picked up about 1-2mpg according to the lie o meter. Cant run straight pipe everywhere but here in NJ there is no mechanical inspection anymore and no emisions for diesels so no worries... only thing this state has gotten right

If you are interested I have the muffler delete linked above for sale. 30 bucks plus shipping

You dont think ditching the CAT first would be better? Lower EGTs? I know the muffler sucks. Just thinking about lower EGTs?
