Hi thanks for the reply. Yea I definitly have the US version which comes with a midpipe / resonator delete. I spoke to exhaust shop today and they said you will definitly know if you have an exhaust leak. I am going to get the noise tested and also get them to check.
Does any one have any reconmendation on a resonator that will fit in the stock location (near the rear muffler) and quiet the exhaust down a little? anything would be great
