Just put on a racing beat header, powerpulse presilencer, and powerpulse muffler, but the header glows? However, the replaced stock exhaust system had no problems, especially no glowing reactor etc. In addition the muffler is spitting out small amounts of uncombusted gasoline.

Could the glowing header be caused by lack of air? This would cause the air/fuel mixture to be more fuel than air causing the chamber to combust hotter than normal. Since the air pump was removed during installation (per installation directions), would it make sense to re-install the air pump to validate this theory and eliminate the glowing header?

Any suggestions?

 

Running lean would make the exhaust hotter than running rich wouldn't it? What year car is it? Do you have all the emissions control stuff still installed?

Without knowing the condition of the engine, I would say to check the exhaust for obstruction, check timing, and check the a/f mixture

 

Sounds like your running fat to me... airpumps take air and run it out the exaughst to hep your car pass emissions...

 

Lean=hot
Rich=cool.

I woulld check your air fuel mixture... Sounds like you might not be getting anough fuel...

Good luck.

I would like you to run your car for 10 miles with the choke on and then tell me your headers are not glowing

 

the rx is an '85 (stock 12A)

the thermal reactor (stock header) and all pre-silencers are removed

the engine has 127,000 miles on it

what is the best way to check the a/f mixture w/o taking it to a dealership?
