Questions about high flow cat

[p33r]

I'm looking for a high flow cat for a DC5S, anyone have any recommendations? Need something that isn't going to burn out within a year or two.

Does cat converter size need to match exhaust size? I'm eventually going to be running it with CRSX header and Fujitsubo PG (60mm) , so should I be grabbing a 2.5"?

Might order through SMSP but really no idea what to grab, will the 2.5" 200 cell spun universal for best flow? Maybe will order through SMSP but really have no idea what to get, should I be grabbing a 3" 200 cell spun universal for best flow? Or is it worth grabbing a 100 cell which SMSP doesn't sell.

Sorry for all the noob questions but pls help!

2.5in 200 cel would be fine...

but email Dave @ SMSP he's the expert...

Will do. Just trying to do my own research first because I heard he's too busy to bother responding to his customers questions

Im running a Venom 100 cel cat 2.5 inch. Im happy it has nice rumble. Downside is it may come into contact with your chassis depending on your set up, as your engine moves back and forward, its sends vibrations down your exhaust, which will make noise much like clunking resulting in rage. [for me it did]
