FAQ
Does this set include one or two gaskets?
The GS33716 kit includes two donuts—one for each up-pipe-to-collector joint.
What symptoms indicate my donuts are leaking?
Black soot at the collector, exhaust smell in the engine bay, slower turbo spool, and lost boost under load.
Do these fit all 7.3L years?
Yes—fits 1994.5–2003 7.3L Power Stroke trucks including OBS and Super Duty, plus 2000–2003 Excursion 7.3L.
Any install tips?
Soak hardware, inspect/true the collector sealing surfaces, and torque evenly. Consider new hardware if corroded.
