Oh my, its $340 dollars. Geez....

Thats a hint for you to make a cheaper one!

Way ahead of you.

Random Technology had a univerasal fit cat last time I asked them that would fit my bonne. I think it was around a 150 but may have been a little more then that.

Thanx guys ,but i still dont know what type of hi flo cat i need that wont mess with the obd.

Get a CATCO from Summit Racing (I think it'* www.summitracing.com), they're about $50 and flow very well.

There is a magnaflow catalytic converter that fits our cars. I actually think its made by CarSound. Hector has the same one.

I'm running an Autosound, but the same size that fits a full size chevy pickup. It was fairly inexpensive. $125 I think? It'* been awhile. Not sure where your O2 sensor is located, so I can't help you with the rest, but whoever you buy one from should know. I'm lucky. I don't have 2 sensors. Just one in the downpipe.
