MagnaFlow Muffler Trb SS 4X9 18 3/3.0MagnaFlow XL Mufflers use a unique combination of large diameter perforated tubing and strategically placed sound baffles to reduce unwanted resonance and help your engine create horsepower. The sound baffles tune the sound waves using calibrated tuning gate openings that allow portions of the waves to pass through. These tuned waves reflect off the back wall of the muffler and cancel out unwanted harsher sounds. The large diameter perforated core

I love this sleeve. Every time I get a new laptop, I buy this exact one. I have one for my work laptop and one for my personal laptop. It’s made from a high-quality outer shell with an equally nice inner lining that’s velvety soft and keeps expensive devices safe. The sleeve is padded on all sides, so no matter what angle you drop it from (and I have), your laptop stays secure. If you have a favorite bag that doesn’t include a padded laptop compartment, this will quickly become your best friend. It also features a generous front zippered pocket for chargers, hard drives, and cables. Check out my video to see the capacity—you can easily fit a full-size charger, multiple cables, and external hard drives. A couple of other things I love about this case: it’s easy to clean (just a damp cloth with a little soap), and it’s incredibly durable. I bought my first one almost 10 years ago, and it’s still going strong. The zipper action is still flawless. For reference, the sleeve in my video is holding a 2025 13-inch MacBook Air, but I have the same sleeve for a 13-inch MacBook Pro, and it fits both beautifully. I can’t recommend this sleeve enough.
