I installed Hooker 2460 headers + Hooker y-pipe specifically designed for the headers and this car.
Problem is, the rest of my exhaust system doesn't go together with the y-pipe.
The Hooker y-pipe replaces the catalytic converter with a straight 2.5" pipe:

Is there any catback setup that would directly bolt onto this Hooker y-pipe?
I'm trying to get my car to pass the inspection as soon as possible.

 

95% of all catbacks require some sort of minor work to get them to play nice. My y-pipe was 1/2" short of the cat so I had to take it in to have some material added so it would mate with the cat.
