I want to put a system on my truck with dual tailpipes when I do my DPF delete - any suggestions or recommendations?
I also may put some type of muffler in to cut down the leaf blower sound and replace it with some throaty rumble - has anyone achieved this?

 

No rumble here, but if you find one that works out please share with us.

 

I bought the MBRP dual exhaust set up (DPF back) in 2008. To me, it does look nice. Of course, it's purely a cosmetic thing. No performance gains expected or gotten. I've been considering a muffler of some type too, just so it's a little quieter driving in the neighborhood.

 

I couldnt find a dual setup on their website that was turbo back or down-pipe back, just filter back systems. I wonder if they use the DPF delete pipe ahead of the system when removing DPF?
I think its Magnaflow that has an option with their kits to have a pipe / muffler interchange so you can run with or w/o muffler...

 

If you want a deeper noise get a 4 inch down pipe.

 

 

I like the symmetrical look of those duals!
That look from the rear reminds me of my 2003 dually. I had a Magnaflow on there.
Do you run a muffler / resonator of any type?
I cant find a part # for a down pipe back system on their site.
Is it just a filter back system with the DPF /DOC delete pipe in front of it??

 

I cant recall the part # and I just threw the box out the other day!

It is the cool duals "filter back", aluminum. With delete pipe in front ( I painted black)
No muffler/resonator.
Sounds quite a bit deeper, still a bit of the hair dryer sound at idle/high idle but it is clearly less and deeper sounding. I like it.

 

For some reason, Magnaflow duals both exit the same side. I dont like that. The MBRP looks real nice.
I also like the Banks duals - they have unique looking tips that I like the style of... the duals and the quad piped duals

 

Longview, were those the tips that came with the Cool Duals??
