    Gt40p exhaust manifold/header suggestions

    What header/exhaust manifold is available for GT40P heads on EFI 5.0/T5 combo in ‘65 coupe?

    Also have following:
    ‘65 early motor mounts
    MS brake booster/cable clutch setup
    Modern Driveline T5 crossmember
    2.5” true dual exhaust to valence panel

    I put HiPo mannies on my 5.0 with GT40P heads.......did a test for spark plug install/removal.....no clearance issue with that task. 
    With those mannies, you can purchase an exhaust system with a matching H pipe that will not cause extreme gluteus maximus pain.  I purchased my system from brother Glen and Steve and I have the same engine/trans combo as yours in my coupe. Scroll through my project deadhorse posts....i included a pic or two of the exhaust tips exiting the GT valance.  I'm using a 2" exhaust system.....

    Thanks Josh.

    I’ll check out your dead horse project in more detail.

    I remember catching bits and pieces.

    Sooooo many projects,sooooo little time.

    Doing research right now.

    Appreciate it.
