U-Bend Replacement
 Pictures
Our 97-99 Grand Prix's have two O2 sensors built in. Because of this, the second sensor is placed in the exhaust after the catalytic converter. To make it fit and protect it from the elements, designers made a 'u-bend' shown in the picture above.

This reduces exhaust flow quite a bit and companies like Ram Air Technologies have made replacement pipes.

RAT charges $99 plus shipping for thier units, but I found a shop locally that will make them and ship them for $55. If you would like one made for you, send me an email ewong228@yahoo.com and Ill give you more info.

Unfortunatly, I don't make the replacements anymore. My friend moved on to something better and no longer works at the shop anymore. But your local muffler shop should be able to do the Ubend replacement for you.
