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.

Designed to fit the 2000-2006 Mercedes-Benz S430, 2000-2006 Mercedes-Benz S500, and more, this direct-fit catalytic converter also interchanges with OE part 220 490 07 20.

Worked on slow leak… one month already!!!
Style: 18oz
Edit: Still holding proper pressure at 2-months !!! Had a slow leak where my tire went from 44psi to ~18psi over 2-3 days… Dashboard light would let me know every few days that I had a tire problem and I would inflate the tire back up to 44psi… Anyway, I used this product and filled air back to 44 psi and it’s held the pressure for a month already !!!! Be sure to deflate tire to ~15 PSI before adding the product… it only took about 30 seconds to empty the container into my tire with the tire pressure low. Very happy with this product !!!

Effective temporary fix
Style: 18oz, Style: 18oz
The slim brand has always been an genuine effective fix. I have been using slime since I used to ride on bicycles. Well it is not a permanent fix for if you have a hole in your inner tube it is a great fix to hold you over until you are able to get to either the mechanic or to your local store to get a replacement inner tube. Overall, it's worth every penny and you get plenty in the canister that it comes in depending on which slime you are getting whether that's the plastic bottle for your inner tubes for a bicycle or the metal canister as I've shown in my picture for your SUVs trucks or vans. However I don't give this an entire five stars but more of four stars not because of their product but because resorting to using slime rather than fixing the problem is more of my own problem. ⭐⭐⭐⭐ 👍👍

Don't buy doesn't work
Style: 18oz, Style: 18oz
Terrible did nothing. Even tried to let wheel turn 360 degrees yet the solution get in the tire leak proper. Directions on can differ from instructions on here/Amazon. I followed directions on can EXACTLY and still didnt even hold one PSI of air. I'd be better off burning the $10 for warmth rather then waste it this way
