No inlet tube on your car. That'* an emissions sampling thingie.

Inlet 2.5"
Outlet 2.5"
Length??? Dunno. Just buy one, and they'll make it fit Or measure.

Don't waste your munny on a name-brand for a cat. Buy a carsound. Same performance, virtually a straight pipe as far as backpressure is concerned, and alot cheaper. One of the 'big three' makes the carsound, anyway.

Mine was $125US installed. It'* a 3" inlet/outlet, with custom flanges. Wanted to make sure it flowed well, but still did it'* job as far as emissions are concerned.

I recall you removed your resonator? Let us know if the sound changes any from the cat. I did mine in the reverse order, and didn't notice much.
