Overview:

The Flowmaster® Outlaw axle-back exhaust system is specifically designed for the 2018-2023 Ford Mustang GT coupe and convertible with the 5.0L engine. This bolt-on system is constructed of 3.00-inch mandrel-bent 409S stainless steel tubing flowing into a pair of our race-proven Outlaw® mufflers for an aggressive exterior sound with a noticeable interior sound level. The 3.00-inch tailpipes exit through the factory cutouts in the rear valance and are finished off with quad 4.00-inch polished stainless steel tips giving your Pony an aggressive look that matches the sound. This axle-back system retains the factory resonator mid-pipe. Check out our optional Scavenger® Series No Resonator X-Pipe #817817 for even more sound and power. This Outlaw system is designed for vehicles without active exhaust valves and uses the factory hanger locations for any easy installation you can do at home in about an hour. Includes easy to follow instructions and all necessary hardware needed. Note: Requires cutting the factory mufflers from the mid-pipe for installation.

    Gentle and Effective Daily Fiber Support
    Size: 500 Count (Pack of 1)
    Gentle and Effective Daily Fiber Support I’ve been taking these NOW Psyllium Husk Capsules for a few weeks now, and they’ve been a reliable and gentle way to boost daily fiber intake. Each capsule is easy to swallow, and I like that they’re vegetable-based, non-GMO, and free of unnecessary additives. Unlike some fiber powders that can be gritty or hard to mix, the capsule form is super convenient—you just take them with a full glass of water, and there’s no taste or texture to deal with. I noticed improvements in regularity within the first week, without any harsh cramping or urgency that some fiber products can cause. These really help with digestive comfort and maintaining a steady rhythm. One thing to keep in mind is that you do need to take several capsules per serving to get the full fiber benefit, so the bottle can go quicker than expected if you’re using them daily. Drinking plenty of water is a must with psyllium, otherwise you may feel some bloating. Bottom line: A clean, effective, and easy-to-use source of daily soluble fiber that supports gut health and regularity. Great choice if you want the benefits of psyllium without the hassle of mixing powders.

    This is magic on earth.
    Size: 30 Count (Pack of 1)
    These pills are actual magic. It’s not a placebo. I genuinely feel so much more calm and relaxed when I take one of these. It takes about 30 minutes to kick in, and I immediately feel my anxiety ease away. I usually take them on a stressful day or when I feel uneasy. They don’t upset your stomach, but you will be burping the smell of lavender.

    Best alternative to other anxiolytics and anti-depressants
    Size: 90 Count (Pack of 1)
    As a healthcare professional, extensively studied this supplement. It's one of the best available in market to treat Generalized anxiety disorder along with other subthreshold anxieties. It really worked for me. Far better alternative to SSRI and benzodiazepines.
