Hey guys I just wanted to start up another group buy thread for everyone who wants to upgrade their exhaust with a header but doesn't want to drive around in limp mode burning lots of gas.

This is a simple device that splices into your second o2 sensor to trick the ecu into seeing the first catalytic convertor. This is a MUST for anyone using the OBX header or Wagner header with cat-less DP for my supercharger kit.

The prices will be:

1-10 = $15 shipped
11-25 = $13 shipped
25+ = $12 shipped

I am using this on my P5 right now and can testify to it's worth. I've driven with my CEL on for several months now. I've averaged about 250 miles on a tank. The very first tank of gas with the MIL showed me 402 miles. With current gas prices you can see how this would save you lots of money. Also, now that I'm not running in Limp mode my car feels much stronger.

20 or so are ready for immediate sale. Payment can be made directly to me via paypal @ "perrymuk@bellsouth.net" NO CREDIT CARDS OR E-CHECKS Money orders also accepted. Make money orders payable to:

p.o. box 224

As with every GB I run a portion of the proceeds will go back to the forum to make sure we have a place to come to.

thanks a lot.

p.s. Also, very detailed instructions with pictures will be included with each order. This modification took me less than 10 minutes with no tools other than channel locks.
