    Roger, pipe size generally is dependent upon horsepower. THIS TABLE should be a good rule of thumb.

    I have 3" pipes all the way back to the exit in front of the rear wheels. When I have the shop take those off and run them out the rear, I'm dropping to 2-1/4" pipes. I'm not worried about perfect tuning of the exhaust anymore. It's close to what's in that table, and I'm not drag racing or running at top RPM very often. That's my semi-scientific/kinda-practical approach. Works for me.
