Probably just oil from the machining process. You shoulda seen my engine bay after i put on my new header. Start it up, let it run for a little. If it stops, it was just oil. If not, you may have some other problem.

Hey, I just installed my performance curve/flowmaster catback today and after taking a short cruise I smelt something burning so I look under my car and the pipe has smoke coming from it. I immediately turned off the xj. Not sure what this could be...anyhelp? Thanks, Rob

Any of you guys removed the factory front cats before? I am replacing mine this weekend and am wondering the likelihood of me needing a torch to heat up the bolts to separate the flange.
It's a 2000.

Will the PB Blaster do much with it being directly attached to the manifold? It seems like it gets pretty hot in that area.
This is the system I am going to run.
Stock manifold - AP Front Cats - AP Front Pipe - Walker OE Converter (couldn't pass the price on EBay, got it for $60 new) - Magnaflow Performance Curve System on back.

Alright so I ran into a problem today. My tailpipe was rusted enough that it broke off right flush with the muffler. It certainly is louder now and I kinda like it lol but until i can get it fixed I'm wondering if this will effect any engine performance. I apologize that this has nothing to do with the conversations before me, but this was an exhaust thread so I thought I'd post about it. Thanks
