I was at the track friday and saw that some cars had an o2 sensor at the end of their exhaust, clipped on the tip on the muffler, with a wire going back into the car through the trunk...does anyone know who makes these and a price?

Thanks. Tom

thanks, but i think the ones i saw were different...the exhaust clamp on the innovative looks different i think...do you know of anyone else making something like this? Thanks

 

anyone else?

 

Why not get a bung welded into your DP, cost you in the $20 range

 

/\ +1. My downpipe came with a bung already welded in place. Very conveniently placed by a rubber grommet to run through. I would go with this option..
