Default Glowing exaust at the track

Hey guys. Well I got an 02rs and I was running ym car realy ahrd...I would say low 90s high 80's most of the track on turns ect for about 10-15 min strait. Well I Slid off course and after getting my car back on I went to check the underside and I noticed my exaust was glowing red/orange. I was wondering if this is a normal thing for the speed and the time I was driving...or was somthing damaged in my stock + cobb intake car?
Thanks for opinions.
If you want the rest of the story go into mwic forums andread on how my car crashed...

Wow...first time I heard of an exhaust glowing from temperature. That must've been a scary sight.

I don't think it's normal...but then again, nothing that is "faulty" should cause your exhaust to glow. Is it the piping that's glowing or the muffler canister?

I've seen some pics in magazines with engines on engine dynos, and the exhaust is a nice cherry red. It could happen, especially given the temps and run time you indicated. I'd suggest if you are going to be doing that in the future (running the car on the track, not sliding off!), that you get some extra oiling capacity in addition to sythetics, as well as an EGT gauge to make sure you're not running too hot/lean.

A collage student? So, an art major?

Glowing exhausts on turbo cars are not that uncommon. My RX7 did it normally, and not even from hard driving. I've never heard of it happening on a production NA car, though.

Is it the headers that are glowing? Headers glowing are more "commonplace" I think.

People have talked about getting the turbos to glow after a nice mountain run, so I'm sure that on a track you could get the exhaust to glow further down.

Not to scare you, but my friend had a Civic that got a clogged cat. It was glowing red and melted his shifter. Watch out!

If you are taking your car out on the track (no matter what car that is) you will need to uprate parts of your car to deal with the stress of high-rpm running. If you can't afford to take care of your car (collage student or not), you will eventually suffer long-term effects. An oil cooler and synthetics are not expensive. I woulnd't consider running my car regularly on the track without at least those two items.

it's normal for exhaust to glow when being run wide open for a longer period of time. it just heat soaks. He's doing allright, i got the exhaust in my parents minvan to glow when the distributor cap carbon tracked and it was misfiring. Talk about cherry red.

BTW DoctorNick has a oil cooler and he does run synthetic.

I make sure he's not doing anything TOO stupid, like hitting poles and such.

Too lean, maybe not, try to rich, if you are dumping fuel into the exhaust it could be collecting in the cat and burning there which would cause that nice red color. Saw it on an RS-S/C's cat when one of the cylinders wasn't firing.

If you get an aftermarket exhaust (scoobysport for example) without cats you'll get flames coming out the exhaust and pops and bangs on the over-run!! Scoobys generally run rich so you'll always get stuff burning in the exhaust. You'll also get the turbo to glow after you've been caning it around.

Probably because he changed his car description and it no longer says 2.5RS, just 2002.

DoctorNick - you do know that higher octane fuel has less energy in it don't you? Octane is a combustion inhibitor. Use the cheap stuff unless it knocks.
