OEM Grade Direct-Fit Catalytic Converter

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-178. 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. This direct-fit catalytic converter is designed specifically for the 2009-2015 Cadillac CTS and interchanges with OE part 22940825. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems.

Easy to install.
Size: H307 (12")
Great replacement rear wiper blade for my 2018 Toyota Highlander. After watching a YouTube video on installing this wiper blade on my vehicle, anyone can do it. Thank you You Tube!

Quality Windshield Wipers
Size: 17", Style: Latitude Repellency
These wipers are a solid upgrade over standard blades. Installation is quick and straightforward, and they fit securely once attached. On the first use, you can immediately notice the difference the wipe is smooth and consistent with very little streaking. The Rain-X water-repellent feature actually works, helping water bead up and roll off the windshield for better visibility during heavier rain. They also run fairly quiet compared to cheaper blades, which is a nice bonus.

Does what it says
Size: 22" and 22", Style: Latitude Repellency
These are my favorite wiper blades. They install easily on my Dodge Challenger and work well as wipers. But I like the little bit extra of RainX repellency to help water bead off my window in between wiper swipes.

Not streaky!
Size: 26" and 17", Style: Latitude Repellency
These work really well! They are not streaky, which was the biggest thing I was hoping for! They also aren’t too noisy, thankfully! They were easy to install too! I have only used them for a couple of months and so far they have continued working well!

Good wipers
Size: 22", Style: Latitude Repellency
Bought these wiper blades because my wiper blades were old. The new blades lay down a good level of water repellent on the windshield. I actually drove home this morning in a rainstorm and purposely did not turn on my wipers once, and the windshield stayed nicely beaded and cleared, a month after I put the new wipers on my truck. I recently bought my s/o a set for her vehicle. They’re expensive, but seem to be worth it. Very quiet, no chattering, 30 seconds to install on my F150.
