I have a 6.9 in my Bronco,should i be running dual pipes, as it looks from the y section it divides into the one pipe.
What size pipe should i be using, and what type of muffler should i have.
My current set up is a 2.5 inch from the y section, to a single muffler to a resinator at the rear. I am thinking this is not the correct set up, thus having too much back pressure, any info would be appreciated.
Cheers

The most common set up for duals is usually a 2.5 or 3" set up with a flowmaster or magnaflow muffler on each pipe. Some folks use cherry bombs, but the sound is not so pleasant. Try to find a good straight through muffler and use two of em and you should be all set.

Any pics of that Bronco, sounds like a pretty cool truck. Scotty
