Hi guys. I'm new to the forum, but not new to Nissan. I live in the virgin islands and I have had a 2000 Nissan pathfinder for 5 years, and a 2007 Nissan Xterra (which is my current vehicle) for 7years. Hoping I could get some help with a cold start noise I'm having. Also thinking about changing the exhaust pipe because of poor design causing back pressure on one side of engine. So as soon as my wife gets home with the vehicle and it's cold enough, I'm hoping I can upload a video of the noise im experiencing.
