I am running the Edge EZ box and possibly larger injectors. I want to install
a larger 4" exhaust system with good flow but not the loud droaning that some systems have. I will run a muffler but no cat. What system would best meet these requirements?

 

ah if it was me, i would go straights! my stacks just aint loud enough.


but i hear that the MBRP kits are nice.

 

After all my research I have decided on the MBRP 4" T-back. A local guy has it on his truck and took me for a ride and that sealed it, nice sound around 60-70 mph, and not really drony. I'll re-post after mine arrives and installed.

 

I just put that system on my '01 3500 dually yesterday. Sounds good, and not too loud. Sounds like a real truck now. I got the stainless and it was a snap installing the thing. Including removing the old one, I think it took my son-in-law and I less than two hours to finish up. Of course he has a gas hatchet which makes removing the old one much easier. Everything in the kit lined up exactly like it's supposed to and it went very smoothly. I have the long bed so I didn't have to cut a thing.

 

I have the flow pro 5 inch on mine but I took off the muffler. But this system is a really great system and its was only 350.

 

I put a MBRP 4" on several guys and they real liked them, sounded good out side and not mutch inside. I have the MBRP 5" but removed the muffler, whats the point in 5" if it sounds like the 4". the only thing I didn't like was that it used the 4" down pipe, but I will take care of that. you can get the aluminized for 4" for $360 and the 5" for $550 comes with the same life time warrenty as the SS. MBRP makes a very good kit and I think one of the best exhaust you can buy. Made my 5" on my old truck.
