2 1/8" TTI Headers

I had the 2" pro parts in my dart. Always ran Hot on the street. Went back to a fenderwell ( Hedman this time ) car went back to running 180 tops in traffic. I also had to modify 1 pipe to run my Indy Sr heads. really wish I would have done a before and after drag strip test too. it sure seemed to Pick up with the fenderwells vs the pro parts.
