Overview:

Keep the check engine light off with MagnaFlow HM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 24178. 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 2004-2013 Mazda 3 and interchanges with OE parts L353-20-55XH, L326-20-55XK, among others. Avoid potential exhaust leaks by using the included gaskets to get a proper seal.

Perfect Fit for My Tesla!
Size: Upgrade - For Model Y Juniper/Model Y/Model 3
I’ve tried a few phone mounts for my Tesla, but this one stands out. It attaches securely without any wobbling, and the magnet is strong enough to hold my phone even on bumpy roads. The sleek design blends in well with the car’s interior, making it look like it was built for it. Installation was super easy—took just a few seconds. The charging feature works great too, so I don’t have to fumble with cables while driving. If you’re looking for a reliable, stylish phone mount for your Tesla, this one is definitely worth it!

Good mount for iPhone in Tesla
Size: Upgrade - For Model Y Juniper/Model Y/Model 3
Easy to use mount. Helped provide additional visibility while driving. Sticks really really strong to the surface. Also have an option of ac vent mount instead of sticking it on dash or back of screen. Strong durable material not plastic.

Versatile quality product.
Size: Upgrade - For Model Y Juniper/Model Y/Model 3, Size: Upgrade - For Model Y Juniper/Model Y/Model 3
The beauty of this phone holder in my Tesla Y is that it can be moved from corner to corner based on needs without worry of sticky glue issues… current setting is lower right corner and happy with things so far. Will absolutely update if my feelings change but so far I’m stoked with the purchase. Also the discount didn’t hurt either $$
