a friend of mine just bought a 06 cummins and wants to order just the mbrp muffler. he has been lookin everywhere and all he has found is the 04.5 to 05 mufflers. are the mufflers diffrent from 05 to 06?

 

why not go straight pipe

 

Why not go Donaldson?

 

I'm with Dixen

 

whats a Donaldson??

 

Donaldson makes mufflers and filters, it would be cheaper. look for them at truck shops 18wheelers and what-not

 

Donaldson mufflers, if I'm not mistaken, are made for 18 wheelers and the diesel truck people jumped on them, and now they're making them for everything...I think....hell, I could be wrong.

A diesel mechanic turned me on to them and I found them online. I know that I had to go to Fleetpride to get it, and I know that Fleetpride is a big rig place.

I love mine. The only thing that I would have done differently is get a shorter one. It's a little too quiet. It has a nice deep "growl". It's not obnoxiously loud like my last truck (MBRP and high flow). (For everyone that has straight pipe, I'm jealous of it when you drive past, but I don't know if I could take anymore on a day to day.)

Anyway...look em up on the net. They're good. Don't go as long as I did if you get one.

 

Try TruckPro for Donaldson also

 

Anybody have a 4" Donaldson part #?
Thanks,
Tim
