I have an ef si hatch the previous owner had it kinda riced with a big exhaust and I been looking into changing it. I find the hks sport twin tip exhaust very sexy.
but I have a d16a6 engine and would like to get a b series in the future b16a sir.
do B series headers and D series headers hook up straight to mid pipes? like universal or is it a big mod.. ect. I'd like to get hks sport twin tips and keep them ! weather if its for a d or b series.
thanks!

 

No big mod, depending on which header you run, an adjustable test pipe should solve your problem. Many people run the HKS on both B and D motors
