Discolored Tips?

[pvteye]

I have had the MagnaFlow Rolled Tips on my MagnaFlow CatBack with the stock H pipe for about 350 miles. Everything was fine.. tips stayed nice and clean the whole time. About 150 Miles ago, I had the MAC O/R ProChamber installed and now the Tips are discoloring... they have that slight Brown / Bronze tint to them that the CatBack got after a few hundred miles of driving when I first installed it. Anyone else had Tips to discolor after going with an offroad H or X? I am guessing it is Temp related, however I would have thought the Exhaust Temp would have gone down with removing the Cats..
They polish out just fine and look as good as new.... but prior to the ProChamber they never discolored at all...
Thanks,
Rex

I have always had o/r pipes and everytime I wash I always polish the tips. just the nature of the beast.

Ever look behind you after gunning it, mine smokes with my off road pipe. I would just imagine it comes with the territory.

It's unburned fuel that's sludging up as it cools on the tips...the cats are there to absorb most of the unburned fuel that gets in your exhaust, and when you went with the o/r prochamber it's letting that gas get all the way back to the tips, where it cools and cokes up on them...
