However, we at Kline take perfection very seriously, and as a result felt we had to take our GTR exhaust to a whole new level. How could we achieve this? With a combination of elegant design, uncompromising materials, acoustic, and fluid dynamic modelling.

THE INNOVATION

The 3.8l v6 engine being mounted at the front of the GTR, designing and building an exhaust with a high standard of sound and performance might be considered a fairly easy task. However, we at Kline take perfection very seriously, and as a result felt we had to take our GTR exhaust to a whole new level. How could we achieve this? With a combination of elegant design, uncompromising materials, acoustic, and fluid dynamic modelling.

Setting the benchmark, the world's first GTR exhaust made entirely from Inconel 625 formula one grade material. Inconel is very light weight, our GTR system being one of the lightest resonated 89mm system in the world. Inconel is also incredibly durable, with high thermal and chemical stability, and will not fatigue and crack over time like titanium systems.

THE SOUND

Removing the quad 400 cell catalysts, and replacing them for either de-cat pipes, or 100cpsi catalysts, increases and enriches the sound, as well as improving torque and power response. replacing the resonated y-pipe for a free flow variant further accentuates the sound as well as lightening the exhaust. enlarging and simplifying the rear silencer section, we were able to essentially consolidate the volume of the 3-silencer factory setup, into a more efficient twin rear silencer design, further lightening the setup. the rear silencers have been volumetrically tuned towards removing bass drone at cruising speeds, while giving a rich aggressive vocal at high RPMs. Built from Thin sidewall Inconel, with high latent resonant frequency, the sound is accentuated in the treble frequencies, giving a higher pitched more aggressive sound when you need it. The Inconel sound really is quite electrifying!

PERFORMANCE

De-cat variant, 48hp gain @ 6500 rpm
73nm gain @ 3800 rpm

Such a great new product from Sun Bum
New product from Sun Bum - love it! I gave it a try after getting a bit too much sun on my arms and chest at a soccer game and it worked great. So soothing and calming. Takes the sting off right away and reduces the redness. This will become a staple in my bag for me and the kids this summer.

Good after-sun spray
The pros: We have used this a couple of times after getting more sun than we wanted, and it seems to work as advertised. It has a cooling feel to it, and seems to soothe the skin well. It's not greasy and it absorbs well -- I didn't notice I had it on it after initially putting it on. It doesn't have a glow or shine to it. It also has a very minor fragrance -- not one that's noticeable. The size is great; you can take it with you on vacation and even put it in your carry-on. Perhaps most important, I am glad for the more natural ingredients involved -- ones that aren't toxic. The cons: It's a little expensive, as most sun bum products are. And it seems to work well, but I feel like aloe works similarly.

Great Hypochlorous Spray!
I love Sun Bum and I regularly use hypochlorous acid in my skincare routine, so I was stoked to try this! First, I have sensitive skin that’s prone to redness, dryness, and acne. Hypochlorous acid has been a godsend on days where I need a toner step but my skin doesn’t want to tolerate anything. Hypochlorous acid is also great for acne healing and prevention. On top of all of that, it’s good for general skin healing so this can definitely be used on the rest of your body wherever your skin may be irritated (please use common sense here lol). There’s no scent which is great and exactly what you’d want in a hypochlorous acid spray. The way it feels is comparable to magic molecules hypochlorous acid spray, which is what I’ve been using until receiving this one to try. It’s like a very watery toner. The spray itself is a fine mist and doesn’t feel like getting blasted in the face lol. It takes maybe 30 seconds to a minute to dry down after spraying a few sprays on your face, just depending how dry your skin and climate are. It’s a great base for literally any other skincare and it’s also a great refresher to spray on top of other products during the day. It really does it all. As far as value, I will say even though the price is comparable, you get more with magic molecules. I’ve included some photos to compare the bottle size. While I’m thrilled to try this for free, I don’t think I would repurchase unless it was on sale/better value than the MM version. It is a cute little bottle and looks good with my other skincare, just in case that’s something you care about. The bottle is fully plastic - no glass. Some may prefer that and some not. I find it really easy for chucking in my bag/traveling. I haven’t noticed any issues with leaking although I truthfully haven’t traveled with it that much. I’m giving this 5 stars because it’s a really solid choice for a hypochlorous acid from a great brand and it’s sensitive skin friendly!

Works grear
I'm big fan of Sun Bum and their product lines. I burn easily and my skin gets sore even when protected so I use a lot of after sun products. This one is a good on the go product. It does a good job at moisturizing the skin while smelling good at the same time. Compared to other brands this product pricing a grear value for the money. I will be adding a can to my after sun routine.

Seems to help
I usually really like Sun Bum products so I was excited to try this. I am on vacation in FL right now and spending a lot of time in the sun. I got a bit burned the first day so I used this that night. It’s meant for the face but I also used some on my arms. It has no scent at all. I’m fine with that. It is a watery spray. So when you spray it on your skin it sort of beads up. I suppose you can let it soak in but I was impatient so I rubbed it in. It did not sting and it did leave my skin feeling somewhat moisturized but it’s not like using lotion or cream. It did not reduce any of the redness from the sunburn although I’m not sure if it’s supposed to. But my sunburn did not hurt the next day after using it. To be fair, I use tretinoin cream so my face is especially sensitive to the sun. My skin gets irritated very easily but this spray did not bother me at all. For myself, I’ll probably continue to use sunscreen for sunburn aftercare but this spray is convenient and it doesn’t leave any residue like creams would.
