Should be 2 1/4" cat body around 14"-16" can find out for sure on monday. We have these in stock in both magnaflow and catco, depending weather you need one or two 02 sensor mounting locations.

I only show a cat up till '98 v-6 and that in universal shows 2.25" both ends. I doubt the size has altered any. Thanks for asking

Social Networks:

it is 2 1/4" in/out if your exhaust is all stock. If your exhaust isn't stock, then buy a universal fit to match the size of your aftermarket exhaust.
