Made of T309 (1.4828) Grade Stainless Steel and Hand-polished to a mirror finish.
These High Performance Sports Catalytic Converters feature 100 cell per square inch substrate fashioned from the highest quality materials currently available designed to improve air flow for your vehicle and increase performance.
The cell count of a catalytic substrate refers to the number of holes per square inch and is a direct indication of the flow capabilities of that substrate. The lower the count of holes the bigger the hole need to be to fill one square inch, a bigger hole subsequently flows more exhaust gasses.
All of this High flow will not help if the substrate is ‘squeezed’ into to small a diameter can or pipe. For this reason, CAPRISTO Sports Cats come packaged in 5.2 inch packages to maximize exhaust gas flow and operation of the valved exhaust system.
The CAPRISTO valved exhaust system helps low rpm torque by providing back pressure in the exhaust, and raises temperature for good catalytic converter operation. While in the open valve condition for high rpm, it takes full advantage of the free flow characteristics of the CAPRISTO Sport Cats optimizing the high energy exhaust at the ideal temperature and back pressure to maximize performance.
These catalytic converters can be easily fitted to a CAPRISTO exhaust systems or any system that fits directly to the OEM exhaust.
*Recommended For Off-Road and Track Use Only*
Replacing Your OEM Catalytic Converter/s may trigger a CEL (Check Engine Light).
To disable a recurring CEL you will need to tune the ECU.

Great Clean Alternative to Traditional Mouthwash, LOVE this!!
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I’ve been really impressed with these Boka mouthwash tablets. They’re fluoride‑free and alcohol‑free, which is exactly what I was looking for, and the hydroxyapatite is a nice bonus for supporting enamel without the harshness of traditional mouthwashes. The tablets dissolve easily, the flavor is refreshing without being overpowering, and there’s no burning sensation at all. Do NOT chew and swallow like I did the first time. Chew, get salva going and swish. My teeth never felt so clean!!!
I also love that they’re travel‑friendly and cut down on plastic waste compared to big bottles. My breath feels fresh, and my mouth feels clean without that chemical aftertaste. If you’re trying to switch to a cleaner, gentler oral‑care routine, these are a great option.

Tasty, effective, and helpful against thrush
Flavor Name: Citrus Mint, Size: 3.5 Ounce (Pack of 1)
This is a good plastic-free, portable form of mouthwash. Pop one or two tablets in your mouth, chew well, add a little water if your mouth is particularly dry (mine is), swish, and spit. That's it. They don't burn like regular mouthwash, and they leave a nice flavor that isn't overpowering and that lasts longer than other mouthwashes have for me. It's a balanced flavor, if that means anything to you - basically, my mouth somehow feels right afterwards.
I was skeptical about the claim that these improve the mouth microbiome, but they've virtually eliminated the thick white layer (presumably thrush) that I've been fighting to clear off my tongue forever. So, yeah, these are definitely a winner.

More like a mint candy than mouthwash.
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Hard to describe this product. Does it work like your typical mouthwash? No. Does it leave your mouth feeling minty and fresh? Yes, to a certain extent. Would I consider this an alternative to mouthwash on a consistent basis? No, it's ok for traveling because it's easy to transport.
When you chew this tablet, it has the texture and feel of a traditional mint. It's chalky and breaks up easily.
