you can either get some longtube headers, a shorty h/x pipe, and THEN you can bolt those up. or you can get the Y pipe adapter (cheaper route...but not nearly as good) that basically turns your y pipe into an h pipe. leaves the 4 cats on though and keeps stock manifolds so exhaust flow sucks. depending where u live the first one might not even be an option. you could also maybe do some shorty headers and whatever mid pipe (stock GT one if you live somewhere like cali, offroad or catted if you care about emissions).

but simply no you cant bolt a GT catback to a v6 without doing something else. 1 of the sixer guys might confirm this but i thought the SLP's sounded like *** on a v6 thats why most of them go with flowmasters or something.
