New Exhaust and DP question, tried searching

[theswoleguy]

Hello Gents,

I have done some searching but just want to confirm. I am in the process of again upgrading my exhaust due to outlet location being infront of the passenger rear tire and that wheel n tire becoming powder coated soot black every 2k miles or so after cleaning. I was looking into finding a 4" downpipe system but just to confirm is the only true 4" dp system a magnaflow? My MBRP is a 3.5" dp. From what i have read, a 3.5" is perfect for the VGT setup, and a 4" is better for nonvgt (thus my setup). I know the power level will not be that much more substantial but the EGTs will drop a hair more.

So is my only option a magnaflow kit or a custom kit say MBRP 5" with someone else's downpipe?

If so whom makes a true 4" dp?

thanks in advance

The summit brand exhaust was 4" DP, I bought mine back in '05, so I don't know if they still are.

So you are running compounds now?

[theswoleguy]

nope just the 72mm

My Silverline has a 4" dp, I do not know if they still do or not, mine is a couple years old.

Diamond Eye should be a 4" DP to 5" pipe. If I remember correctly.

hopefully we will find out soon, thanks about the wheels - are they the same ones you have in your pic of your truck?

[Leroy88]

No not the same. Thats my old truck in the avatar pic. My new truck will have those wheels on it as soon as i get lug nuts for it. I have Eagle 297 in 18x10.
