Apex Cat-Back Fittment question?

[ErockGSX97]

Im interested in getting an apexi N1 cat-back exhaust for my car. My question is is that if i get one, say 3" one, will it fit correctly with the catalytic converter because i want to keep that on there. Everyone talks about taking it off, but for now i really dont want to get rid of my catalytic. And just an add on question, but everything with a 3" should fit right with how the car is already set up with out much work? Thanks

it comes with an adapter so you can bolt it to the stock cat

it bolts up to the cat easily with the adapter. and when you wanna do the downpipe get the apex'i one and save your old downpipe,cat,and adapter in one piece so you can bolt the whole thing up for emissions

thanks for the help, but then otherwise hooking the cat-back up to the car itself should not be a problem at all?

As long as you can get the O2 sensor out......they get a little stuck from time to time!

what does the 02 censor have to do with installing a cat-back?

because there's an 02 sensor there

you said that the O2 censors sometimes get stuck. how do you get that out?
