installed my APS 3.5" nd Greddy EVOTT. It's smoking a lot. It go away after a few weeks, but didn't think it'll smoke this much. I also haven't ran my car for a month and the temp is at around 220. Is this normal? I'm not talking about hard driving, either.

 

I see 190 on the highway and around 205 running around town if that helps.

Did you have cats before the APS pipes?

 

^ no, I had same size downpipes before. My oil temp went up to 230 after 50miles of driving I'll bet it's the damn, walmart mobile one 10-40s wannabe synthetic. Anyways, after some driving, the crazy smoke subsided a bit.
