FEATURES
- MODULAR SOUND - Select your sound with ease thanks to the modular nature of the xMOD Series. To change your vehicle’s sound simply swap out the exhaust system’s central module, which is secured using easily removable, racing-bred V-band clamps. Each kit comes with three modules, including a standard Muffler Module, NDT (No Drone Technology) Module and X-Pipe Module. Specifically designed for the 2020-2021 Chevrolet Corvette
- NO DRONE TECHNOLOGY - Like the standard Muffler Module, the NDT Module features MagnaFlow’s deep signature exhaust tone while further utilizing MagnaFlow’s No Drone Technology to keep unwanted droning noises under control, especially at cruising speeds
- X-PIPE MODULE - When you are ready to unleash your engine’s sound and fury the X-Pipe Module is exactly what you’re looking for. This component essentially transforms your performance exhaust system into a racing-inspired straight-pipe setup, perfect for track days. Check local noise regulations before using this module on the street
- DYNO-PROVEN PERFORMANCE - At the MagnaFlow Tech Center we conduct extensive testing to ensure that each of our xMOD exhaust systems increases performance by significantly improving exhaust flow
- PERFECT FITMENT & VEHICLE INTEGRATION - The configuration of this xMOD exhaust system is based off detailed 3D scans of the entire vehicle, enabling the engineers at the MagnaFlow Tech Center to ensure perfect, OEM-like fitment. xMOD performance exhaust systems are also designed to integrate and retain factory-installed electronically controllable exhaust systems on relevant vehicles

Gentle Cream Cleanser That Actually Works
If you’re specifically looking for a foam-based face wash, this isn’t one—it’s more of a cream-based cleanser. But honestly, that’s what makes it work so well.
It feels light, not oily, and leaves the skin smooth after washing. You don’t need a lot of product, so even a small amount goes a long way—especially if you pre-wet your face.
It might feel a bit different at first if you’re used to foaming or soap-based cleansers, but give it some time. After about a week of using it twice daily, I started noticing a difference—my skin felt clearer, and some pimples and spots began to reduce slightly.
Overall, a gentle yet effective option if you’re looking for something that delivers results over time.

Gentle, effective cleanser that’s great for everyday use
This is a really nice, gentle cleanser that works well for everyday use. It feels effective without being harsh, and it doesn’t leave my skin feeling tight or irritated afterward.
A little goes a long way, and the bottle lasts a good while. The scent is very light and neutral, which I prefer, and it doesn’t burn, dry out or cause any discomfort on my skin.
Overall it leaves my skin feeling clean, smooth, and comfortable. Definitely a solid choice if you’re looking for something effective but not aggressive.

A must have for young, acne prone skin!
I recommend this product to every one. Its a cheaper alternative that provides real results. I started out using it everyday, but found it works best around my breakouts (usually hormonal). Its help the texture of my skin even out. My 14 year old son uses it daily for his acne and the difference it has made is day and night. It has slite scent to it, but nothing overwhelming.

Very effective!
My daughter had horrible acne and this was the only thing that worked! We tried everything on the market. I highly suggest this if you have a teen with stubborn acne!

Great
This stuff is generally just great. My dermatologist recommended using at least I think she said a five or 8% and I feel like this is just like the perfect mixture with Trention to get your acne to go away, but I use it every time I shower and I feel like it really is a great defense against acne and oil
