hi guys

I need a decat pipe for my jdm hawkeye sti. I have seen the rcm one etc but £270-£300 for a decat pipe seems abit much even to me.
I have seen the japspeed one and people say the quality and fitment is good, this seems to be from 2014 and nothing lately. Is the quality of the japspeed's exhausts still good?
Also most list the jdm decats etc for the spec c, i assume they are all the same?

thank you
