I'm looking to have a shop build an exhaust for me and I was thinking dual 4" straight pipes and preferably stainless but i could deal with aluminized but has anyone had a shop build a system for them and about how much did this cost?

 

I had a shop bend up a 3 1/2" ( no muffler ) for me '86 6.9 a couple of years back , I think the whole cost was under $100. for a single exhaust .

 

Umm - why?? You can buy yourself a system - probably for a lot less than a shop can fab. you one up for.

 

i really dont know a maker that makes dual 4" with the tips coming in front of the rear tires and i thought having a shop make one for you was cheaper then those expensive brands like banks because isnt a really good stainless system like 700-800

 

Why not just do it yourself? I built my 4" exhaust and it exits out the side in front of the rear tire on the pass. side. Most truck supply shops have the tubing and clamps in stock as well as a variety of mandrel bent angles. You could also try www.airflowonline.com they sell pretty much everything you need. I bought my stuff locally, and pieced the system together, the only thing I didn't get locally was my 4" DP which I bought from ITP.
