Yea at this point I may just pay to have it done. Not sure I feel like messing with it again. At one point I did try to trace the sensors back but I didn't have any luck with a quick once over. In past cars I just unscrewed the sensors while I was under the car.

If someone can post a pic of the plugs under the hood before Wed, I'll try it again this weekend. Otherwise I'll just pay to have it done.

Dude, you rock. I actually went to those two plugs but it threw me off b/c the one silver cord turns black and I wasn't sure b/c I couldn't actually see the transition.

I'll be knocking this out Saturday morning....

I was actually able to install my HFC DP yesterday

I posted a before and after video in this downpipe thread: http://www.f30post.com/forums/showthread.php?t=803655

Didn't want to take over Challenge's thread...

Has anyone actually received and installed the Challenge catback exhaust? I don't see anywhere to actually buy it. Impressions on how it sounds compared to stock?

I think Challenge has decided that they don't want to share and their car will be the only car on the streets with the Challenge catback

No, in all seriousness, i don't think they've shipped any b/c they were backed up with production of some other products.

Mike, if it helps any, our car has been running around with the stock exhaust

had to surrender it to the fab department months ago

BO fills plus stock units are in works now though

Catless and HFC Downpipes are in stock and plenty running around on customers cars though
