thats right.
same, anything bigger then 60mm and u will probably lose a little bit of power. like 1 hp lol but unless ur car is BUILT then u might wanna get a 2.5 inch, or if u wanna go turbo then get a 3"

for any B series you want a 2.25" or 2.36" exhaust, this is until you hit the 190whp range as this seems to be the limit for the 2.36" exhaust after that you will need a 2.5"

the owner before me he has install 70 mm diameter exhaust and i think the car in low with middle rpm is not rev very well and in dyno has 19 kg torque and 203 bhp and 173 whp it is good what you think?my opinion is not good

thats good for what you have, your exhaust is holding it back if you have a 3" 70mm one. do you have a Type R motor? Cause no chip would give you 30bhp

I'm going to take a guess that since he is measuring torque in kg he is not local, so his b18c is the type r version, not a b18c1. If this is the case you should look at getting a 2.5 inch exhaust.

really? stock type R is only 2.25" i thought exhaust diamiter was dependent on build and WHP.

yes i have type-r motor b18c
Okay, i suggest a ITR B pipe or 60mm exhaust
