i just ordered a jdm exhaust to match up nicely with my jdm ix rear bumper and plan on getting a hfc instead of a test pipe and i plan on purchasing the perrin hfc. well my question is this the perrin has a bung for the o2 right? so i dont need to drill a hole on the jdm exhaust at all right?

also has anyone else done this same combo, perrin hfc and jdm exhaust and had no issues at all?

 

do you have a 8 or 9? what exhaust did you get?

 

evo 8 and colt speed.

 

if there is not a bung for the 02 in the mid pipe of the colt speed exhaust, you can use the bung in the perrin high flow cat. if you end up getting the exhaust and there is a bung in the exhaust just go ahead and use it for the 02 sensor and keep the bung on the hfc capped off with the supplied screw.
