I agree. Actually, I thought about this first but was afraid of the dreaded Cat CEL.

Not saying it's a bad product at all as I truly have no idea... just discussing perception and/or reasoning for the burn in out of the box.
Good luck  |
Maybe this is also how they differentiate between the Ti and ST exhausts at the factory.

Thanks, I read in another forum that some Autosol metal polish will do the trick.

Removal of the secondary cats will not impact OBD II compliance . Nor, will it result in a CEL .

There's no way the exhaust after a muffler gets hot enough to blue the steel ( or Ti.). More likely, the bluing is from heating the tubing so the tip can be rolled during manufacturing.

Damn, I had one of those systems I would have sold for 750 bucks.... If anyone else is looking for one, let me know. Its a left over from my engine combination development. Hardly ever used.

I am keeping my ears open as I thought about changing to this set. Would like to hear the results from OP though.
I personally like the bluish TI tips.

The only thing I worry about would be the visual, and not the "sniffer" portion of the smog test here in "too late to fix" Cali.

Unless the tester is an expert on boxsters, seeing the pre-cats on the headers should satisfy the visual inspection.
