I am running a b18c in a 98 civic coupe and the stock exhaust doesn't line up with the headers, any answers would be greatfull. searched but no luck on this subject, thanks

 

grab a b series exhaust header , someone correct me if im wrong but all the b series EH's are direct bolt

 

yeah they are all the same

 

well how about this i have a b16a header will that work

 

The length of the piping for the cat is differen't between b18 and b16 headers. That might be the only difference you run in to. Also the height under the car is differen't because b18 blocks are typically taller than b16 blocks.

There about 2mm taller, not a huge difference. Besides the length of them, on occasion I see some flanges being reversed, where the right side is lower when it should be higher, or vice versa. All depends on what header you run, aftermarket or stock. And all depends what your exhaust setup was for.
