Car like that I wouldnt dream of any header other than TTI, Dougs or Schumacher. All above mentioned with ceramic coated are above $700. The Shumachers are easiest to install and work around but also are limited to 450 horsepower as stated by the MFGR. If it were my car Id go 1 7/8" Dougs or TTI.

Keep old mopars alive.
