Ok guys I'm new to diesel bombers and I think I'm doing this right haha. So I was thinking about strait pipeing my 01 cummins and some1 told mr to go all the way to the cat. I was wondering if that's a good idea or not, I would really like the extra smoke but idk much about what that would do. Anything helps thanks

 

Take the muffler and cat out. IMO though, I'd go ahead and put a full 4" exhaust on it myself

 

im running a straight pipe on my 01. i love it, its a full 5 inch from the turbo back with a 8 inch tip, got a nice sound, maybe a little loud for some but i like it.

 

Straight pipe it for sure. That sound is sooooooo sweeeeeet!!!!Sounds like a farm tractor ON STEROIDS!!!

 

1. my truck stock didnt have a cat on it?
2. i have 4" down pipe belled up to a 8" pipe and up to a 8" stack i am selling it if you want a stack its crome and nice, but any how 4" sounds the best....in my thoughts.... it will lower your egts, and sound great!
i would got all the way to a turbo though

 

Agreed

 

NO CAT AND NO MUFFLER!!!

 

i just took my truck to an exhaust shop and they charged $50 for them to take the muffler and cat out and put in a straight pipe. i love the sound too. i have been flipped off more then once for getting on it next to people at stop lights. its awsome!

 

Some people are just to darned serious, ya know!?

 

i got a full 5 inch i paid 300 bucks new and its got a muffler and i like how it sounds not to loud i use to love all my diesel straight piped!!! but im ok with this one
