Need some quick advice

[svtbolt2001]

I know I will be buying the Mini max and I already own the Volant CAI. I need to make a decision on exhaust

Option 1 DPF and Cat delete pipe

Option 2 4 inch turbo back exhaust

Option 3 5 inch turbo back exhaust


I am leaning towards the middle of the road (4 inch exhaust). What do you guys that have already modded their trucks think? Cost worth the benefit?

Thanks

What size is the stock exhaist on a 6.7?

[Andrew010]

Stock exhaust is 3.5" off a 4" double wall DP.

I'd do a 5" DP back exhaust. Sounds better and some say your EGT will be slightly lower.

5" with no muffler?

5" no muffler.

I have a 2012 with a CAI,mini maxx,5" straight pipe DP back
I had a 4' straight and it didnt sound as good so i went with the 5" and you can hear the turbo alot more and sounds way better. go witht the 5" you wont regret it

I've got a mbrp 5" dpf back with a 4" delete pipe. I wasn't gonna delete at first so just went with the dpf back for looks. Months later I couldn't resist and deleted but they only had 4" delete pipes but it was all compatible with my already existing dpf back system so all was good. I can tell you that I have no regrets. Sounds amazing, loud when you stomp on it but not irritating when just strolling around.

Is your MBRP a straight pipe or muffler?

[cc2cuz]

Straight piped and no muffler for me
