i have a set of groupe s headers in my garage to go on my new car but is it worth taking the headers off the jdm version as im sure they have equal length headers already, are they as good as aftermarket ones or should i put the groupe s ones on

 

If you have the twin scroll then your older headers (if thats what they are) won't fit in any case, imho the oem twin scroll headers are pretty good, could do with porting a bit but thats all.

im going to take the twin scroll turbo off and fit a nice garret but just want to know if the headers are worth keeping ???
