Catalytic Converter with Integrated Exhaust Manifold

California Manifold Catalytic Converter

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 5551759. 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 2004-2006 BMW X3 and interchanges with OE parts 18 40 7 514 503 and 18 40 7 514 505, among others. 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 California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Soundcore V20i: Seamless Bluetooth Switching, Long Battery Life, No Drama
Color: Black
Alright… listen up, Amazonians. I don’t write reviews. I avoid them like I avoid assembling IKEA furniture without instructions. But these Soundcore V20i headphones dragged me in here against my will. I’ve spent enough money on headphones over the years to qualify for a small auto loan—Apple, Samsung, Bose… if it had a fancy box and a price tag that made me uncomfortable, I bought it. And yet somehow THESE are the ones that made me stop mid-day and go, “Wait… why do these work better than everything else I own?” Now let’s manage expectations before anyone accuses me of losing my mind: do they sound like you’re sitting front row at a live concert? No. Do the ear hooks feel like they could use a little more cushion? Yes. Do they have noise cancellation? Absolutely not—you will still hear your dog barking, your coworkers talking, and every bad decision echoing in your head. Are they waterproof? Also no. If you drop these in a pool, that’s on you, not Anker. BUT… these things have one superpower, and it’s the one feature that apparently every $200+ pair of headphones forgot to get right: they switch between my phone and computer like they’ve achieved enlightenment. I’m on my computer all day—calls, music, more calls, more music, repeat until I question my life choices. Before these headphones, switching devices felt like negotiating a hostage situation. “Why won’t you connect?” “Why are you connected to the wrong device?” “WHY ARE YOU CONNECTED TO THE NEIGHBOR’S TV??” With these? Call comes in—boom, switches instantly. Call ends—boom, right back to music. No button mashing, no Bluetooth menu gymnastics, no yelling into the void. It just works. The only thing I’ve used that even comes close is AirPods, but try using those outside the Apple ecosystem and suddenly you’re troubleshooting like it’s 2007 and you just installed a printer. These? They don’t care what you’re using. Windows? Cool. Samsung phone? Great. Chaos in your life? Handled. They’re comfortable, they don’t feel like they’re trying to burrow into your skull, and they actually stay on your ears when you move around like a normal human being instead of a statue. Oh—and the battery life? Ridiculous. I keep waiting for them to die and they just… don’t. At this point I’m convinced they’re powered by spite or dark magic. Are they perfect? No. Do they do the ONE thing I actually need better than anything else I’ve tried? Shockingly, yes. For this price, it’s honestly ridiculous. Anker really woke up and said, “What if we just made something that works… and didn’t charge a kidney for it?” Bold. Respect!

Surprisingly Good
Color: Black
I got these over a year ago for less than $25 and I’m surprised with how good they are. I needed something in a pinch just for calls and expected a product that would sound horrible when listening to music, but these inexpensive earphones sound pretty decent. They have an app that allows you to use different equalizer settings giving you rich sound and bass either using their presets or you can set custom EQ. I like that these are over the ear so you can enjoy your music and still be aware of your surroundings. They are light and comfortable, so much so that I almost forget I’m wearing them at times. The hook over ear design is secure enough that I don’t feel I have to adjust them often like earbuds that constantly feel like they’re going to fall out of my ears. You can also use the app to customize the touch features on each earpiece individually and there are lights on the earphones that you can turn on and off and set to different colours. The batteries last a long time, up to 8 hours on a full charge (when not using the lights feature) and they charge really quickly when you put them back in the case. The only thing I don’t like about them is you can’t tap them to answer calls, which is why I bought them. At least I haven’t been able to figure out how to get that to work. But other than that, I’m pretty satisfied with my purchase.

Indestructible apparently
Color: Blue
So I’m really clumsy and forgetful. I got these as a reward for not screwing up a cheap set for a month. Today I dropped the case next to my car but I was in a rush so I didn’t make sure I had both. When I got home, sure enough, one of them was sitting in the garage and I had definitely run over it. Let me just say, I am EXTREMELY impressed with the durability because I ran square over it and it works just fine. I gave them five stars for that but just know the case is not very secure. I’ll be putting a silicone tie over the case from now on. Sound quality and battery life are great and they look really nice. I also barely feel them on my ears and they don’t make me sore. Excellent product.

Great Price, Fit, Quality
Color: Black
Love these Open-Ear headphones. My previous earbuds were hurting my eardrums due to fitting inside my ear canals. These are more comfortable sitting outside of my eardrums. Great sound and fit for an affordable price. I use mine for exercising, walking, biking and they stay in place. Very pleased.

Good starter
Style: KIT
The chemicals are 5 stars, because the Chemical Guys make great and effective products. And they always smell good, but the taste doesn’t match the smell. I wish it came with other chemicals in the kit. But honestly go buy them one by one and get what you need.
