Supersprint Cat bypass pipes 996C2

$250 + shipping

 

what happened?

 

what do you mean? Didn't like the sound.

 

that's all. just curious.

 

might be interested. how much louder will my car be? what kind of gains if any? will i get a CEL? i know the car has 4 cats stock so what will be the effects of doing the cat bypasses and getting rid of two of them?

 

it gets rid of all four cats.

 

yea i just looked some stuff up on it. prob will throw a CEL and dont really want that. maybe ill look into sport cats.

 

pm sent, lemme know what you think

 

My experience with them was no CEL's and I even passed Texas emmissions (which basically just looks for CEL's). The Supersprints move the second O2 sensor futher down the pipe. This requires you to plug the second right side sensor into the second left side port- important to know when trouble shooting a problem. As for sound I liked the volume but hated the raspiness. The raspy sound is a product of the headers. Stock headers have a deeper sound than mine. If someone was to ask my opinion my suggestion would be to go with high flow cats instead of cat bypasses (I'm a horrible salesman!).
