Your car is running rich , gas is burning in the hpipe . Tune your car to a desired a/f ratio and reap the reward of extra power !!!

Could be clogged cats. Are your headers glowing also? If they are you could have a lean condition or the timing could be too far retarded.

Glowing headers does not mean lean man , do your research your spreading false information ... GLOWING HEADERS = RICH .

Thanks, but I'll take first hand experiance b4 I trust something I read on the internet. Read my other reply to you in another headers glowing red thread. Yes they are right that a rich mixture can ALSO cause glowing headers but it is not the only thing. I have seen it first hand that a lean condition will make your headers turn orange.

BTW maybe you should do some more research b4 calling B.S. on someone.

I don't think a lean condition would make your H-pipe glow read. Headers maybe. Even race cars headers glow red when they are running right. It is all about how much heat your letting off. In this kids situation. I believe that it is because he is running too rich or has clogged cats.

Is the line connected from the air pump to the cats? That could be your problem.

Looking in the sig, it looks like he has an Off road H-pipe, Do you even have cats? I couldn't find anything to support that.

Realistically a lean condition causes exhaust temps to be very hot.

Try connecting your vacuum lines all up. Do you have mass air, sd, or a carb setup?

Test your gas milage that is a good sign if your running rich or not.. my tuned 5.0 can get 32miles per gallon if you baby it (highway).. but still 20+ city if you baby it. A engine can run rich for many reasons.. it could be stuck in open loop one of your exhaust sensors might be bad etc.

is your motor missing...i remember you saying your car was loud and that one guys that worked on it said the cats were clogged...do you have a miss in the motor? if so that puts unburned gas down your exhaust and it burned in your cats...the reason the headers are not glowing is because gravity is gonna pull it down fast and settle in a level area: your h-pipe and on and if you have cats, it WILL burn up in there if anywhere...if not, sounds like your o2 sensors are running in a rich or lean condition...have it scanned...if both of your o2 sensors are bad, check your MAF sensor cause its very uncommon to have both o2 sensors go bad at the same time...then again, i bet it looks like you have ground effects! HA! probably makes the ricers jealous since its "naturally aspirated" ground effects good luck bro...keep me posted.

Ahhh, I am reminded of the last time I drank water in Mexico........

Have you looked for a vac drop off? That can be indicitive of an exhaust restriction.

Good luck.

I had my cats glowing once and I couldnt figure it out.
It sounded normal but also backfired some when I stomped on the gas and let go.

It costs me $50 to figure it out.

your vacuum leak or leaks is probably a different prob.

email me at ls3862@yahoo.com if you want to know what I know.
