When I am buying something important I read a lot of reviews and pay attention to to details . I didn’t want to spend a fortune buying Oem so aftermarket was my only other option. This PHILTOP CC is unbelievable in quality and an exact replica of the one I removed. It feels and looks like original quality and matches up perfectly . It came with all hardware and even a how to guide. For the price I am very pleased!

This converter cleared up my emissions code and the car feels more powerful. It's a solid replacement for the OEM part and much cheaper.
