alright got a question. I dont know much about cat-backs so please dont flame me. I am going to buy the apexi world sport cat-back for my 90 hatch. I currently dont have a cat. What will i have to buy so this sytem will bolt up. Will a stock 1.5 or 1.6 cat bolt up to my b16 manifold. Have any of you used one of those ebay special hi flow cats? Will the ebay cats bolt up to my manifold and the world sport system? Please help!
Thanks in Advance

 

Just get the Carsound Magnaflow Cats and get a 18"+ resonator installed after it then your catback exhaust since you got a b16 in your rex..I think you might have to get custom piping. Im not sure, ask some of the b16 Rex members or search.

The WS is a nice exhaust, thats what I ran on my EF. I also had an ebay "high Flow cat" which was essentially a resonated test pipe. W/ that "cat" the exhaust was slightly raspier, but they bolted together fine. But, since you have a B16 you will probably need to have a muffler shop fit the exhaust on there as I'm sure there are differences in where the header ends on a B series VS a D series.
