Kenworth exhaust squeaks

[Casey Hillmer]

Has anyone had problems with kenworth exhaust bushings squeaking on straight pipes. Seems like everytime they get wet, every little bump makes them squeak , any suggestions so be much appreciated . It's on a 2000 w900L with 7" straights

Declare it a "Show Truck" and drive it only on dry days? No???

Actually, sounds like somebody fubared the install of the straight pipes via the mounting bushings. No biggie, go through em and check for loose and mis-aligned.

WD 40?

Have had 3-900's, they all squeeked. Changed one out to neoprene updates and it cleared it up. But short term WD40, yup..
