Mazdaspeed3 Gen2 Stainless Steel 3" Cat-Back Exhaust by Cobb

The layout of this COBB 3" SS Cat-back was chosen to minimize the total bend degrees used to route the exhaust piping for reduced back pressure. The entire system fits within the factory exhaust path to allow the exhaust to be tucked up as close to the undercarriage as possible to achieve maximum ground clearance. Exhaust piping is 3" diameter from the downpipe to the split, where dual 2.5" pipes whisk the exhaust out of the system.

The resulting path of least resistance minimizes back-pressure for maximum power gains. Harsh engine exhaust noise is subdued via one primary resonator and one secondary resonator. These chambered resonators provide sound reduction without adding restriction to the exhaust flow. The resulting mellow rumble sounds and feels powerful, without being overbearing.

This exhaust was designed to meet the 95dB sound restriction even when used as part of a full turbo-back exhaust system. Significant effort went into making this exhaust look as good as it sounds and performs. Both resonators are custom built and finished with beautiful welds. The 2.5" and 3" stainless steel piping has a satin finish for a stunning appearance. The exhaust is finished with two 4" slash-cut, double-wall rolled tips with laser etched COBB logos. The entire kit is constructed of T304 stainless steel to ensure that it stays looking this great for years to come.

This cat-back exhaust will work with the stock or any direct factory replacement downpipe. The two bolt flanges allow slight adjustability for absolutely perfect fitment. Includes all gaskets and hardware, and uses the stock doughnut gasket to mate to the downpipe.

Beat the Humidity with This Citrus Powerhouse
Scent: Bergamot, Size: 16 Fl Oz (Pack of 1)
​In the middle of a brutal, humid Philippine summer, finding a body wash that actually boosts your confidence is a game-changer. Cremo’s Italian Bergamot isn’t just a soap; it’s a full olfactory experience. It opens with a vibrant, tart Italian bergamot that immediately cuts through the heat, followed by the freshness of vetiver, and the neroli blossom adds a sophisticated floral touch. ​True to Cremo’s Reserve collection, the scent is beautifully layered. It builds in intensity as you lather, allowing the earthy, fresh vetiver to anchor the citrus. Unlike many drugstore options, this lingers—stepping out of the shower, you can still catch the crisp citrus and the clean, woody dry-down on your skin. It’s the ultimate reset for a hot day.

I Smell Like a Gentleman Who Owns a Fireplace
Scent: Bourbon Oak, Size: 16 Fl Oz (Pack of 1)
The fragrance is warm, woody, and slightly sweet...that low amber note that smells expensive without trying to smell expensive, which, as we all know, is the actual expensive smell. My wife walked past me twenty minutes post-shower and said, unprompted, "You smell really good." I nodded like I had planned this. The lather is genuinely rich; squeeze a modest amount and it blooms into a thick, creamy foam that covers everything efficiently. The texture is silky rather than watery, which matters more than people admit. Watery body washes feel like rinsing off with slightly scented regret. This one feels intentional. It cleans, and your skin actually feels clean afterward, not just rinsed. And the moisturizing? I wasn't expecting it. No greasy film, no lotion-begging dry patches by midday. Just quietly softer skin that doesn't make a big announcement about it. Now, my honest gripe: the scent longevity has a ceiling. By mid-afternoon you're back to neutral. That's the gap between four stars and five for me. For daily freshness and an incredible morning window of smelling genuinely great, it absolutely delivers...but it won't carry you to bedtime. On value: 16 fl oz is decent, the lather is efficient so the bottle lasts, and the price sits in that sweet spot where you feel like someone who makes slightly elevated but still reasonable choices, which is exactly the vibe this entire product is going for.

Lathers great in a small amount!
Scent: Bergamot, Size: 16 Fl Oz (Pack of 1), Scent: Bergamot, Size: 16 Fl Oz (Pack of 1)
Lathers great for a small amount! A fair price for the amount and rich content. I just bought, used and love it. Definitely will purchase again. I love the sophisticated yet sensible smell doesn't overpower. In my perception it is a unisex scent as I am a woman and bought for myself.
