I have a 98 civic h/b. With a b16, that has a Type-r head on it with a R 4-1 header, i never have had an exhaust on the car so i dont know what will work for an exhaust, i am runing no cats on it . So i am not sure if a regular aftermarket exhaust will work on it, without it having to be modified, any input would be great, thanks

 

When I get money, I'm ordering a custom set from Kteller8, I hear they are good and not too expensive.

 

any 2.5 in catback will be optimal.
