Ahhhhh, didn't even notice the harnesses were clipped in. Just went and looked at the sensors, and sure enough they are clipped. Will see if the wires provide enough slack to put the sensors in the bungs whenever I get under my car next. Thank you so much can't believe I overlooked such a simple oversight. Now to deal with the O2 sim headache after lol

Good way to trap moisture against the metal. I would suggest ceramic coating.

thank you for that quick response. the ebay headers do seem kinda thin. trapped water may destroy them quickly good point. I think im gonna jump on the grenade and be the guinnie pig and try it to see how long they last. ill post up whatever i find out.
I really wanted the wrap for the sound insulation it offers .

here's a thought: instead of going through the troublesome and possibly illegal mods (depending on your location) put the headers on and from the mid pipe have a trusted muffler shop cut an weld some 200-300 cell cats in place of the silencers... it's better than an O2 sim, and smarter than trying to outwit the car that was engineered by Germans. other reasons: more responsible, kinder to the environment, proven solution, minimal loss of power, doesn't throw codes, more legal, not a science project. only downside is possible $400 initial cost.

problem is... how do you connect them to the exhaust? They forgot some flanges didn't they?
If anyone can enlighten me...
