can anybody lend me some experience.....i'm worried that i'm gonna run into problems and i want a head start....i have a 94+ gsr header with a 2.5" collector, a dx high flow cat, and a 2.5" catback....what troubles am i heading for.....thanks

so are you running a JDM ITR header? just bring it straight to the muffler shop after the swap like us normal people.

well that just what i'm asking....what am i in for....i bought the dx high flow cat because the aftermarket gsr header has a o2 sensor spot in it already, it also came with this flexpipe extender thing....but i just wanna know what to expect soon

if you do a b series swap into an 92-95 civic DX/SI.... i recomend using a LS header and LS CAT.

when you have these items unbolt your civic CAT and the LS CAT will bolt striaght up to your civic exhaust. then bolt the LS header to the motor and the header will bolt to teh cat with no modifications... this way no noisy trips to the muffler shop. if you dont want to do that then you are going ot have to slap that gsr header onto your motor and drive open header to muffler shop

ugh that sucks....guess that my only choice cause i already have everything. one other question then....is there anything i can do ahead of time while i have it off the car....or should i just wait to make sure of size?

i recently did a gsr swap in my hatchback and i was wondering wat exhaust and piping i should get? should i still get a civic application exhaust with piping made for an integra? or should i get a gsr application exhaust with piping made for an integra?

It doesn't sound like you will run into too much of a trouble. But i would get rid of the dx cat flow and upgrade to a gsr or Type R flow. I would also upgrade to a better fuel pump, which will give you better performance. Something like the Walboro gsr fuel pump or Holley. Other than that you should be ok until you start making more modifications.
