Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 444227. 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 1999-2003 Lexus RX300 and interchanges with OE part 18450-20110. 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.

Amazing fit, great quality material
Size: 30W x 32L, Color: Medium Grey, Size: 30W x 32L, Color: Medium Grey
I ordered this pair of denim pants in my usual size (30x32) and they fit amazingly. The cut is slim, but not overly tight. The material is the perfect thickness and seems to be of excellent quality, with a slight stretchiness to it. They are slightly softer than most denim pants I have worn. I am finding that they are great for both business casual settings with a button-up shirt and more informal "dress down" type situations with a t-shirt and sneakers. This is probably my favorite pair of jeans that I have gotten in at least a few years, and I would highly recommend overall.

Soft, comfortable fitting jeans
Size: 30W x 30L, Color: Black Rinse
Good quality and a great slim fit, but a bit expensive for a blend. Since they aren’t 100% cotton, they have a slight stretch that makes them more comfortable and softer than standard jeans. I’m happy with the look and feel, but I’ll have to see how they hold up over time.

Very nice and would highly recommend!
Size: 32W x 30L, Color: Medium Grey
The fit is exactly what I was looking for, slim without being too tight, and it fits true to size, so I get that modern look but still feel comfortable sitting or walking around all day. The denim feels soft yet sturdy, which makes me confident it’ll hold up well over time. I also love the classic 5-pocket design. It’s functional and keeps my essentials handy without adding bulk. The color holds up after a few washes, and there’s minimal fading so far, which is a big plus for me. Pairing these pants with a casual tee or a button-down is effortless, they easily transition from work to weekend vibes. For the price and quality, I feel like these are a solid addition to my wardrobe. Definitely recommend if you’re looking for a slim, comfortable, and versatile pair of jeans.
