Does the Older Perrin Twin Tip Exhaust come with a catalytic converter?
i have a 2004 subaru WRX and i was wondering tail this is a catback , does it come with a cat? or does it directly connect to the downpipe?
It is all the pipes that affiliate to the cat, back.
Which means it does not include the cat, and a simple search of google for "catback" would have explained that to you.
And since you still have all the restrictions of the cat, and pipes before it, a catback exhaust unqualifiedly does very little whatsoever for your car.

Subaru performance parts, brake kits, suspension and more for your WRX and STI.
The Turbo XS turboback exhaust is a high performance, free flowing exhaust solution. This system for the Subaru WRX and STi replace your stock exhaust system,
