"Manufactured from all stainless steel including the flanges and polished to a mirror shine this test pipe has proven a solid 15HP gain on the MAHA Dynometer. The factory cat is extremely restrictive by just placing this bolt on pipe inline with you factory or aftermarket exhaust you can unleash the hidden potential of your 1.8T motor for OFF ROAD USE ONLY.

This unit will work on all after market or OEM exhaust systems that utilize the factory flange and adaptor locations. Package includes a new OEM down pipe gasket as well as new hardware.

Note.
This product is intended for OFF ROAD USE ONLY use of this product upon public highways is prohibited. "<ul><li><a href="http://www.ecodetuning.com/shop/cart.php?m=product_detail&amp;p=370&amp;c=18">link</a></li></ul>

it is a very well made peice, comes nice and polished. to get around the cel i used a pony express MIL eliminator, actualy made for a subaru, not the best soloution though. when i get my new rear O2 sensor im using "spark plug non fowlers" basicaly threaded spacers. stack 2 of them, drill the outer one a little to clear the dome of the O2 sensor. put the o2 sensor in the end, screw the whole mess into the test pipe. now the sensor isnt in the main stream of the exhaust. It works, lotsa EVO gus and 1 or 2 A4 guys are doing it without ANY problems.

cel's for over 5000 miles. Also it costs a total of about 8 bucks which is also nice.

I have it in my 1998 and a Neuspeed G2 catback. I have a CEL that is on constantly. the O2 sensor is so close to the firewall I don't know if I'm going to be able to use the non-fouler method. I am going to try to use the diode method from the tech section soon. I have to pass my city emission test in december so I need to figure something out soon or it will be coming out.

Oh yeah, the butt dyno said definate HP gain, and exhaust volume goes way up.

did you have to pull your test pipe to put the non-foulers on the O2 sensor or could you do it will it still installed?
