glowin precat at idle - normal or not? (searched)
while i was trying to find a leak, i noticed that my precat was glowing. (a downpipe is planned,but it takes a few months) the engine was cold when i started it. while i let it idle, it noticed the orange glowing cat.
now is this a clogged precat, or just normal (rich coldstart + air pump) ?
i searched, some guys had the same symptoms, but i didnt find a clear answer for my question.
Thanks, Chris

it is not normal that your precat is glowing... especially when the engine is still cold when you started... check your precat and catalytic converter... it may have been cloged... bad for the turbo
While waiting for your new downpipe, you can take out the honeycomb... that should help...
Btw, what brand did you buy?

damn 
i noticed a lack of power, it seemed to be a bit "lazy" the last ~ 300 miles.
did that harm the engine (didnt WOT it often, i like to cruise
)
i decided to get a hks dp, it's the best bang for the buck over here.

No it's not Turbo'd
HKS is what I have and from what I did as far as reasearch, I found that the cast Iron Mount that mates to the turbo lastst the longest, since the heating and cooling is really rough on the welded type...

You should have the air pump checked. The glowing DP is most likely a resulted symptom of premature wear do to air pump failure and not the cause of the problem itself.
No, I don't beleive your DP should be glowing red on warm up. I've seen that on my buddy's and he had a clogged cat' and bad air pump. Mine does not glow even after sprited freeway runs or drags launches.
