I installed 2.5" exaust when we did the conversion but I also installed a new Jeep V8 muffler. You can hardly tell the thing
is running from the back. I propably could have done without the mufler?
How do you crank up the fuel?
I'm also changing the air intake from a 3' long 1.5" pipe to a 2' long 2" pipe to help air flow.

Thanks for any help.
