Large Bore HD 409 SS Cat-Back Exhaust System with Dual Rear Exit by aFe. Exhaust System Type: Cat-Back. Exhaust Tubing Material: 409 SS. Main Tubing Diameter: 2.5". Exhaust System Sound: Aggressive / Loud. Get increased exhaust flow, more horsepower and torque, improved performance and lower exhaust gas temperatures with the aFe Large Bore HD Cat-Back Exhaust System. aFe dyno tests every system for maximum gains, and constructs them from mandrel-bent stainless steel for maximum flow and long-lasting durability.

A performance exhaust system is one of the most common ways of improving a vehicle's operation. The theory is simple; just reduce restriction to increase exhaust flow and you gain power. But all exhaust systems are not created equal; in reality there's more to it than just selling some sewer pipe sized tubes.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size and muffler construction. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. An 8" diameter by 30" length, straight, flow-through, perforated muffler is included in the system. A straight muffler delete pipe is also included if a more aggressive sound and maximum flow is desired. This system will increase exhaust flow by up to 29% and lower EGT (Exhaust Gas Temperature) by up to 100 , with a corresponding improvement in power and performance.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The muffler and all pipes of the Large Bore HD system are constructed from durable 409 stainless steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded on each side to ensure a strong attachment and the hangers also feature swaged bayonet ends to lock in place once installed. The factory mounting locations are used throughout and a 2-piece tailpipe facilitates adjustment.

Every system comes with clamps, hangers and detailed instructions to guide you through the installation. The Large Bore HD Exhaust System is made in USA.

Worked well near the equator
Style: SPF 50
I bought this product because I was going to be in the field for a month, outside, every day, all day, in Tanzania at high altitude. A severe sunburn would be hard to treat in the remote area we were in, but also I am very careful about protecting my skin from aging. I had to have mineral based sunscreen because as a whitewater kayaker I know it’s the only truly water resistant kind and it was going to be sweaty. And since I knew I was going to be putting it on every day, and we didn’t have running water in the field (bucket showers only) I didn’t want it to feel gross. (I really wanted to try the spray but I didn’t want to put anything pressurized in my luggage.) And I had already discovered the Coola face sunscreen (30spf version) which had impressed me with how silky smooth and not greasy it is. Now this IS greasier because it is a higher SPF. BUT I think this product is as good as you’re going to get with the protection you’re getting. Like I said, I’m a white water tiger, so I have used a LOT of mineral sunscreens. This was hands down the most comfortable one I’ve used. And it was effective. I didn’t burn once—only time I did burn was when I forgot to put it on one day toward the end of the trip, when we were out for just a couple hours—and I got the first 2nd degree burn I’ve ever had in my life. That was what this stuff had protected me from, all day every day, the entire trip. I did tan a little but I think that was mostly from the few times I was not covered during short bouts or it was cloudy. For my face I used the Coola 50spf face product.

Love this stuff!
Style: SPF 50
I use this every day and I love how it is frangrance free and creamy. I have a very fair complexion and I will say it leaves a slight white cast but it doesn’t bother me because it almost makes my fairness more creamy looking. My skin texture has improved since wearing it daily and no allergies from it. I highly recommend especially if you have fairer skin otherwise it may leave a cast .

Excellent mineral sunscreen with minimal white cast.
Style: SPF 50
This is one of the healthier sunscreens I’ve found so far. You’re not likely going to find a mineral sunscreen that doesn’t leave some white cast. However, this one rubs in pretty good with minimal cast. You can dab on and rub in fairly easily… as long as you don’t use too much the white cast should be minimal. I am not sure how well this would work on darker skin tones. My arms are a medium skin tone… my legs are more of a light-medium tone. I prefer mineral sunscreens, and this is the best one I found so far and compatible to Supergoop mineral play. If you liked that one, you would likely enjoy this Coola one too.

Would not recommend
Style: SPF 50
I literally never write reviews but felt compelled to write one for this sunscreen because I was very caught off guard by all the positive reviews. This sunscreen leaves the most insane white sheen that never soaks in and gets on EVERYTHING. I put this on and drove to the beach and had sunscreen on my car seat, the steering wheel, the center console, the door, EVERYWHERE! It took forever to clean up and was such a hassle and that was after having let the sunscreen soak into my skin for an hour. Also the sunscreen is really thick and difficult to spread and makes you look ghostly white. Plus, the sunscreen has a really odd odor that reminded me of play dough? That might not be a negative thing for everyone but I found it unpleasant. There are definitely better mineral sunscreens out there. For the price I expected a much better product.
