Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 444503. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. Designed to fit the 1996-1999 Nissan Maxima and 1997-1999 Infiniti I30, this direct-fit catalytic converter also interchanges with OE parts 14012-41U21 and 14012-55U00. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Perfect fit for Kia Carnival

The designer of this van made it difficult to find a good solution for phone mount. I tried 4 different mounts until this, and it's perfect. The only problem is the holder itself- it's kinda crappy. The good news is that the mount uses standard sized ball joints so I took an old magnetic mount and mated to this, perfect phone mount.
