it bolts on 'after' the two cats.

 

I almost got one of those systems a while back when they were like $459.00. The guy from Summit Racing told me that it was a universal system, unique in the fact that it can be used with single or dual cat cars. The only problem with the system is you need to use your existing cat or cats back pipe and fit it to the new exhauat. My dilema was that the my existing pipe was killed Right after the cat so it didnt work for me at he time.
Excellent system though!
