I put 6" stacks on my truck but have no DPF. You probably will notice very little noise change with the DPF in place. Mine is very loud straight piped.

I have found that most MBRP Stainless Steel Stack customers have a little buyers remorse. Not because MBRP is not quality, but because the Stainless Steel never shines deep like chrome.

Secondly, if you are installing any larger stack than 5" the MBRP bedkits (to my knowledge) are made out of 4" tubing and jumping up to the 6"+ is done at the base of the stack.... Kinda looks like lolly pops.

I no MBRP has good Fit and finish, but take some time to look at some installs... There is nothing like Chrome. Grand Rock is the only Chrome I know of that has a warranty on the Chrome Finish.

Just an opinion..... $1500.00 can be cut down to size as well

No sound difference at all, however you may feel like you just got kicked in the nuts by not spending that money on fuel instead... but I bet they'll look great :thumbsup
