Power Strokes 1994-1997 Upgrades and AftermarketUpgrading or adding OEM or aftermarket equipment to your 1994-1997 Ford F-Series with Power Stroke engine.
I have a 4" exhaust system with a straight through 5" outside diamer short glasspack racing style muffler. I get a lot of drone at 60mph speeds and was looking to quiet the drone. Does anyone have any suggetstions?
My other truck with 6" exhaust, which is flex over the axle has very little drone and is actually quieter in the cab.
Thanks.

My Magnaflow muffler is a 36" and it is almost a quit as a stocker. I would highly recommend it. No drone at all. Exhaust will bark a little when towing but there is no drone.
