Dynatech Headers
Thought I would roll under my truck and snap a pick of my recently installed Dynatech longtubes and the high flow cats. Ceramic coats done were Nitride coatings.

Re: Dynatech Headers
NICE!! 
I just ordered the Dynatechs and took delivery a few days ago. Paid $679.00 w/free delivery for Headers alone.
AutoAnything told me it would bolt up to my OEM Cats. Took it in for installation today but no dice ... I need the HF Cats and X Pipe $500.00 more!!

Re: Dynatech Headers
You will want the high flow cats anyways, all that extra exhaust coming down needs a quicker way out. You wouldn't get the full effect of them without the HF's. Excited to see what you guys think when you get them, hopefully you will like!
