Here is a pic of my exhausts after car was initially running well at the track with a REVO flash and straight pipes no cats. Second run car started to stall out on up or down shift. Can anyone tell me what is wrong with the air fuel mixture from this picture?




Would like some help before I get the dealers version.
thanks in advance

I think that's usually a result of running leaded fuel. I wonder if the stalling is due to a faulty O2 sensor or damaged cats?

I'm not the most technical guy though so I hope someone can give you a better idea...

 

Looks dangerously lean?

 

thanks for the input, I thought lean also. the leaded gas comment is also correct cause when it started stalling I didnt want it to detonate if it was lean so I added some race gas.
to dealer tomorrow!

thanks again, anyone else??

 

if your runnin leaded fuel that a normal color if your runnin unleaded it's to lean..........good luck

 

If you added leaded fuel you killed your O2 sensors no question about it. that will cause enough drama right there.
Im not sure but I might have some 02 sensors I can give you.... I don't need them anymore...

 

thanks again guys, to the dealer!!

 

My C16 coated tips look exactly the same.

Tom - My exhaust tips looked almost the same from the track - not quite so much white on the outer edge but definately on the inside. I did not have any trouble and the darker normal color appeared again a day or so after normal street driving.
Was this from Sebring a couple of weeks ago? I stopped to say Hi but you were away from the car.

 

Craig, Michael, well I feel better then, still going to the dealer to have a check up!!
thanks

 

Tom - FYI - I have been using GermanTech in Largo - not hard to reach via 275 - if you need any help talk with Joe Vatter, the owner. He has done all the mods on my car, and several other tt's too. This is TechArt stuff and so far has been very reliable. Joe knows all the folks at Reeves/Bert Smith/Suncoast.
