DPF back exhaust.

[Rob]

Has anyone swapped their exhaust from the DPF back? I want to get something along the lines of the MBRP DPF back kit, if it will work with my DPF delete, i cant stand the split tip.. does it change the exhaust sound when going to something different or is the "hair dryer" sound still very prominent when driving? links to any videos?? thanks.

You could do a Magnaflow with a muffler. Keeps a throaty sound at WOT, and gets rid of a lot of the hairdryer noise at idle and part throttle.

Got any links to that setup?

Here it is on Xtreme Diesel's site...

MagnaFlow Filter-Back 5" XL Performance Series Exhaust System 16984

It's priced high, but you get both a muffler and a muffler delete pipe in the kit. Someone else may be able to do it cheaper. I got my Magnaflow DPF back exhaust for my delete pipe from Rudy's and it was priced well.

If you get a kit with a muffler, the hair dryer sound isnt as prominent. The MBRP DPF back kits do not include a muffler so you may want to go a different route. Magnaflow is a good option, I suggest the 5". Ultimately, it would be best to just get a down pipe back exhaust and sell the delete pipes you have. This way, you have a 4" or 5" system without the weird 3.5" slip joint between the delete pipes and the DPF Back kit.

I agree with DSTRBD, I did the 5" SS Magnaflow first and than the 5" SS Flo-Pro. Where the two meet they're the same size, 5" I.D. and I needed to put in a piece that was 5" O.D.. If I had to do it again I'd get a 5" down pipe back sytem, Its easier and a cleaner look. Just my 2 cents.

P.S. I'd buy from Performance Truck Products, Great people and Great prices.

It is 4", but tis bent in a spot for clearance. Most people just leave it stock.

Where actual exhaust flows it's only 3" in diameter.

It is not necessary for those running regular (not race) tunes. Sure it will help drop temps some, but its not worth swapping out with regular tunes unless you are trying to squeeze every little bit out of the truck. Most people find their EGTs to be very manageable with the stock DP.
