I agree with that. With the X-Pipe the chambers can mix properly and my o2 sensor can get an appropriate reading. I agree with what was mentioned about trying to get my O2 sensor as close as possible to the headers so it will heat up better. A second thought about the cats has also deterred me from the dual in dual out style cats. I'm not sure about the width in the tunnel or how wide my pipes are apart from each other. Rather than complicate things having more bends and such to get them to line up I might be better off with 2 singles. I'm still lost though so I guess the car is going to the exhaust shop for their expertise. If I can fit it and afford it I'd like to get those 2 cats with 2 of these resonators.

Ended up purchasing 2 of THESE . I'm sure they'll be great. I'm going to try and cut / use the resonators that are built in to the OBD2 stock mid-section. we'll see though - it beats buying new ones.(oo=[][]=oo)

Hopefully that helps U pass smog. Note that those particular magnaflow cats don't function as thoroughly as their other range, they are the "racing" cats
