Hey jmans - you do realize that removing the cat on a street vehicle is illegal right? The fines run pretty high too. And if you live where there are emission inspections you won't pass. If you went to all the trouble of replacing the whole exhaust why not put on high performance cats & be legal?

OP, try this link:
Oxygen Sensor | Air/Fuel Sensor | DENSO Aftermarket

good luck.

Wait!... Your mechanic cut it out?... Are those long tube headers?...

Um make a bung reinstall them.. IE HFC's.. Not sure why you would cut the Cats out anyway?

that was awesome black betty :biggthumpup:

uh...so your mechanic "friend" installed custom "dps" (your cars not fi - test pipes) without the added function of installing O2 sensors? you sure your friends a mechanic? he must have something against you. by the way, you're car's about to blow up. exhaust + test pipes + headers = your ecu can't compensate for the added O2 flow. it's a known fact with those modifications = your motor will blow; probably already has. :(

your friend's a douche.
