The part number for the replacement exhaust is correct . The exhaust an AMG part does not match the exhaust on my car or does not match the the drawing in the parts book. I need the left side. The part that came has two cat. converters. One at the top and one half way down the pipe and then an extension of pipe. The one for the car shows one top cat. and two at the end. The right side hooks into one of the converters at the lower end. I cannot believe a mfg. would design a system with two converters hooked togather and if one went bad you would replace two. Chrysler Service is involved and said the parts are numbered incorrect. My question as the dealers is, what does this new exhaust part fit. Chrysler said its not an up grade for the car. The car is running hotter than usual and seems to slow down faster when you take your foot off the gas. The dealer suggested just drive the car 1300 mi. home and repair it there. I was supprised to find out the exhausts are the same for all Crosfires. Thanks for the feedback.
