Dual Exhaust Question
I have a 76 F100 with a 302 v8. I plan on getting dual exhaust for it, do i need an h-pipe or x-pipe to balance the flow or is this a myth? Also what mufflers have the best bang for the buck. I can get a good deal on some unused Original Flowmaster 40 series, how good are they?

You dont NEED one, but its a good idea to have one. Mufflers....you will get hundreds of opinions. If you like the sound of 40 series, go with them. I dont like much of the Flowmaster line. Check out http://exhaustsoundclips.com/ford.html and see if there are any mufflers there you like.

2.5" pipe is too big for 302 engine. It will actually hurt your low end torque and gas mileage. Too big for optimum exhaust velocity. 2.25" mandrel bent tubing would be the largest for a 302.

You should be fine... almost all dual catbacks go with 2.5" piping. Not sure you'd feel a noticable difference with 2.25" going from the catback. A full exhaust on the otherhand... I'd go no larger than 2.25" piping. JMHO.
A 302 equals 5.0l and the 5.4l equals 330 cubes.

Hey Stevef100s, you sound like you really know your stuff. Do you think that 2" pipes would be too small for a 302 with, longtube headers, no cats and flowmaster mufflers- a true dual exhaust system?
