I just finished my gsr swap into my 92 cx. It doesn't feel as if it pulls as hard as my b18b did, could that be the fact that I still have the crappy cx exhaust? Will driving around with this exhaust hurt the engine any because of excessive back pressure or anything like that? I know I need a new one and it will come soon but just wondering? And by the way should I try and take it to get reffed with the stock exhaust? Oh yeah, this is my first swap and no CEL on first startup

 

i think the ls has a tad bit more low end torque. the stock exhaust definately isnt bad for you engine but it is slowing your car down a bit. i noticed a big difference goin from stock piping to my apexi n1 after i swapped in the b18c to my old coupe. as for the smog crap i dont know anything about that. i live in fl where we dont have emissions testing

 

yeah thanks for the response, I will get an exhaust soon........maybe new cat too
