I've done a search through a bunch of the Carsound threads already, and couldn't come up with a straight answer yet. I have a stock '94 GS-R, looking for a Carsound cat b/c my stock one is worn out. I should be needing a 2 1/4", single O2 bung universal cat, correct?

The Carsound website recommends the 91034 model. However, ImportechPerformance (H-T Sponsor) sells the 94000/94100 models, and I've also heard I should get the 53000 series (which are shorter).

Which is the right one?

Bump for a bit of help.

I'm from Canada, but I'm visiting SoCal for a couple days, so I'd like to buy a cat while I'm down here.

Thanks guys,

Up again...
