White Bros Carbon Pro Exhaust help

Recommended Posts

I have a 04 Honda CRF 450 with a White Bros. Pro Carbon Exhaust. The fit from the header pipe to the muffler isnt tight, causing bad popping when i decelerate. Is there some kind of shim or clamp that can seal the fit from the muffler to header?

thanks :thumbsup:

Put some high temp silicone on the pipe before putting it together. If you want, you can run an exhaust clamp on it (a hose clamp may even work).

A lot of times back firing can also be valves out of adjustment

yeah i was thinking that too but it only backfires during deceleration and it runs perfect otherwise.

i was thinking of just hose clamping it shut

thanks for the tips :thumbsup:

Thanks for the tip. High temp silicone withstands temps to 450 degrees. That may not be high enough, but may be my only option.

Thanks:ride:

You might wanna try adjust your air/fuel mixture about 1 full turn out before you start messing with the pipe

High temp silicone will hold up. Both FMF and Dr. D recommend using it at the midpipe joint.
