Exhaust manifold Glowing Orange

[BM2KTom]

I just noticed on my 98 Camry 5S-FE after short drives my down pipe on the exhaust manifold glows bright orange from the heat, I dont't know if I should worry about this or is it just something camrys do, the only modification I have done is removing both the intake resonators I am wondering if this is increasing airflow and causing a lean mixture. Any help is greatly apriciated, thanks.

ive heard of this happening from cats getting clogged but they usually complain of performance issues as well. check your cat.

Thanks for the advice guys, if it is a clogged cat any advice on how to clean it out, I know its connected to the manifold it self but am I going to have to take out the exhaust manifold to get at it, thanks.

i'm sorry but when something glows like that there is blockage. i dunno how to clean it. but either knocking out the ceramic material with a chisel and hammer will cure it but illegal. or simply replacing the cat.
since the cat is like a thick honeycomb, i don't know if there is something to clean it with
