Any shops in the DFW where they can play with 4'' pipes? Mandrel bends is a MUST thanks.

 

Dont you already deal with Bryan at MK? :p(and Sam)

Honestly, id just buy a 4" system for a duramax and cut down the length to fit. 4" will be tight out back with a flip kit though, I had only 6" rear drop on my old CC and it was tight with a 3.5" magnaflow tailpipe section I was going to put on it.

You can easily do 4" from the Y-pipe back to over the axle then get the 3.5" over the axle section from magnaflow to go over the axle and out($65 from summit, free shipping) 4-5ft of 4" pipe is cheap too I might even have some laying around from my diesel days...

 

I always liked Muffler King, stay away from Gentry's in Denton

 

Well with the Turbo they installed a Duramax MBRP 4'' system but cuts of after the axle, since a bigger cam is going in I wanted a tailpipe so I won't have drone, most shops can't bent 4'' pipes

 

Ill call the shop I always use tomorrow and see what he says.

 

It came up a bust!

 

Both mandrel bent/stainless

3.5"(wont be losing any power just using it for the over the axle section/tailpipe
