Hi! I recently got a good deal on a fujitsobo power getter backbox. The problem is I did some research and it says its for the GTS, I have a 2005 EU-spec GT. Will the exhaust bolt on without problem or is there a difference in the diameter of the piping leading up to the stock back box. Also, will it ruin performance if it's not intended for the 1zz. Thx in advance.
