I wasnt sure where to post this, so I put it here where the turbo guys will see it. Edelbrock has a 4" Duramax exhaust on sale for $100. It could be adapted to fit 1/2 ton trucks too. It looks like such a good deal I had to pass it along. Supposedly there is a coupon code for free shipping too, but I couldnt find one. EDIT: looks like the code for free shipping is "freeship".

I'd buy a couple if I knew I could sell em. That deal will NOT last long

 

hey guys, I'm selling 4" exhausts for $150 shipped, must prepay, just let me know

looks like mild steel, yes?

 

I tried to buy 2 of each, and it says "I'm sorry, we do not ship to that address."

 

I can see next week we will have 20 new exhaust threads with video.LOL
