Who is useing Header extensions?

lol.... or the vert could be too loose. Kinda what i dealt with for a while.
Hoping it works better behind my 418 than it did the 360
Well then! Best of luck!
I’m not the best with automatics or converters. I get the main idea though. I’m prepping my first race 904. Normally I bang 4 gears with a pistol grip. Pro Torque used to be down the block from me until there move to Pa., so I speak with Joe directly for help on this and other racers in my area. It’s been a real long time for me.
