Exhaust System and Manifolds

We recommend a 2.5” all the way back, no cats. with a 3” inlet and outlet 6” round Walker Ultra-Flo muffler. This is not smog legal and therefore should only be done on cars that are only driven on the track. When driving on the highway always run your cat under the car. We offer High Flow replacement cats for under the car in both 2.5” and 3” diameters. We do not believe in 3” pipe systems for Street Starions. We don’t want to argue with everyone so I will say that… Yes we feel a 3” system will make more power on an extremely modified car running big turbos and big boost… But on a street car it will cause poor off boost driveability and laggy response. 2.5” is sufficient for all street systems up to the high 300 HP levels. We run 2.5” from the Turbo back through a 2.5” catalytic under the car and exit through a 3” muffler. This gives good response and sound while allowing a very free flow system. For now we supply the components to do your own.

Oxygen Sensors

            1 wire O2 sensor                                                                                                       $45.00

            3 wire heated 02 sensor with 2 bolt flange plate                                                     $79.00

Another thing to try with the stock F.I. system is to put a toggle switch across the input from the O2 sensor to the ECU ( just splice it in right where it plugs in in the engine compartment on the right side above the ABS ) and turn the O2 off under hard driving and high boost conditions. This will usually keep the car a bit richer as the O2 is not trying to correct the mixture.
