ok with my build and everything done now i have the dc sport header with test tube wich has no cat on it and it is also only 2 inches. and there is also a lil raspiness left to the exhaust so i am wondering what cat i should go with ? do i wanna do a race cat? or do i want just a highflow cat? and this will be staying magnaflow product so what do you guys think. and i am also supercharged so i prob dont want much restriction on the exhaust . idk im stumped and could use your guys help

Do you have a resinator installed? If not that'll help take care of the rasp.

2.5" maganaflow high flow OBD2 Complient over a year over driving 14,000 miles 0 issues.
My setup.
pacesetter header into magnaflow 2.5" cat into 2.25"x26" resenator into stock piping into a 2.5'x12" maganflow res into a 2.5"x12" turbo thrush muffler. decently quiet till you romp on it. I like it. and teh stock pipe and 2.25 res was to keep more of my torque at low end. still flows plenty.

what was the part number on that one?

If you search this forum for threads that I started myself, you'll find a link that compares the regular bulky style cat to this one. These are the best flowing magnaflow cats.
