'10 Camaro cammed HOT exhaust

[Christian GM]

hi guys,
about 3 months ago I tuned this Camaro using a wide band and the BLue Cat program.
it has Mast Motorsport stage II cam kit, CAI, 160°F thermo, full exhaust by LG with high flow cat.
the car runs great, powerful no more surge or anything else.
BUT when I check the car on the lift today I was scared.
I'm afraid the exhaust is too hot.
what you think about it???

thank you!

best regards

you have cot disable tn the tune you posted. i would start there.

thank you.
what exactly does this function? and when?
I'm scared that too much hot near the fuel lines on passenger side can be dangerous. Also customer say that when vehicle is very hot the engine dies.
maybe due to fuel evaporation in the lines?
I pay attention when I did the fuel to have the car properly fueled to avoid dangerous lean condition (and it suck a lot of fuel!)

thank you

what are your LTFTs reading?

[DSteck]

Exhaust leak.

[Christian GM]

LTFT are good near 5% or less.
@ DSteck, why you say "exhaust leak"?

thank you

[DSteck]

Because the heat shields have burn marks where there are joints in the exhaust.
