Troubleshooting: Glowing DP
So I have a log manifold, SR20 t25, and a 3" exhaust w/ cat. Heres the issue:
I picked up my car from the shop and it had a very weird metallic rattle (much like pinging) coming from the exhaust. I pulled over and I noticed the downpipe was glowing for about 4" where it attaches to the turbo. Let me tell you what I have diagnosed so far.
It is not detonation (the sound is localized) to the turbo/DP
The turbo compressor side spins freely with no signs of hitting
My AFR is not off, and neither is my timing.
Has anyone had something like this happen? I want to say it is a clogged cat, however, the cat is fairly new, but it is a cheap one.
