My only complaint is that the plastic Packing Slip holder and Manufacturer Part Number label were stuck to the piping and required about 45 minutes worth of scraping, pulling, and rubbing with Goof-Off to remove these sticky items from the exhaust piping. Was a real PITA. I didn't want them melting on the hot exhaust pipes, so I wanted them removed. I'd suggest, wrapping the exhaust piping with shrink wrap plastic first and then sticking these items to the shrink wrap for easier removal and preparation for installation.
