Worth watching 355 back fire, how does this happen? http://www.youtube.com/watch?v=GAOFzkEp7hQ http://www.youtube.com/watch?v=eCzQIeBxfX4
most all the 355 will do this IF you have test pipes or cat deletes and a tubi or other aftermarket muffler where the exhaust is actually not filtered with packing
