thanks postban, but i couldn't really hear it from your video. My engine bay is pretty much quiet except for the tick from teh injectors. Its loud outside if you listen below the driversside mirror. I was listening to a brand new 10th anniversary cobra and it was completely silent but still had the injector tick in the engine bay.
Its possible i may have an exhaust leak but i've tightened it as tight i can so many times its hard to beleive.
