Made for the JDM DC5R. The JDM DC5R headers are different to the AUDM DC5R (Exit on a different angle), so it's not a direct bolt on, and it won't fit perfectly if you are using the stock headers.

I think it sounds shit... but some like it

No... not really. On an otherwise stock DC5R (No ECU/Intake/Headers) you are only going to get a placebo effect, in that you'll think you are going faster because you can hear your exhaust.
