I have searched and found two different sizes listed. What size is the exhaust? Would it do any good to just cut out the muffler and leave the cat? How loud will it be that way, and how loud with no cat or muffler? Anyone have any sound clips? Thanks

 

its is a 600 series it should be 4"

 

4" exhaust. Some leave the cat which does sound good. Straight is too loud. I used a 41" Donaldson with no cat.

 

2004.5 to current is 4".

 

x2 on no cat and a 41" Donaldson

 

x3..

Its a great setup.. .thou the EB was annoying when idling and walking around the truck, so I put a MC resonator on.. now its perfect.

 

OK so it sounds better with no cat and a 41" Donaldson. Where do I get that at? Does it sound better than if it was no muffler and a cat? Which one will perfrom better. Thanks again guys!

 

It will flow and sound (IMHO) the best without the cat and with the 40" Donaldson. And it smells better too.

I got mine here

 

Does my truck have an EB I don't think it does but someone mentioned it above. Thanks!

 

I run mine straight and love it.

 

Kyman,

Well first off Welcome to DTR! Second fill out your signature so we know what truck your running and what your mods are. That will help us answer your questions.

 

OK thanks will do. Then you can come back and chime in on my questions

 

No Problem...but just going off of the thread title if you have an 04.5 stock from Dodge it did not come with an exhaust brake.

 

I didn't hink so, but someone had mentioned one. I think I am going to try the Donaldson and no cat, I would love stacks, but with a toolbox and pulling a white enclosed it may not be a good idea. Thanks for the help
