Inliners International Forums General Discussion Engines pipe size for 250ci

I ran 2.5" off the headers on my 250.....Due to cross members on the 4x4, I had to y them together into one and dump it out in front of the rear wheel on the drivers side........Works ok. I am running a glass pak.

We had a '69 C-10 that we ran 2.250 from the stock exhaust manifold to right behind the cab, did a 45 degree turn and then a 90 in front of the step box fender to a stack.........It was the most awesomest sound out of a gas engine that I ever heard!
