- Looking for a header to complete the look and performance of your AA slip-on exhaust? Then you need the AA stainless steel Pro R header! The OEM header is an odd 2 into 2 into 1 design and has many areas to improve upon. We set out to make a functional header that looks great.
- Nearly 6RWHP peak and over 4 RWHP max gain over the stock header when used with AA ECU flash and AA slip-on exhaust. This is nearly 8-9 crank horsepower gains at 60mph and does not lose any bottom end power.
- Excellent low end to top end performance
- Works great with our level 2 tune, clutch kit & other performance products
- Baseline(OEM header) was tested, then we quickly swapped our final header design in place to show the most consistent/real gains in the same hour of each other.
- Engineered to have equal length runners into the collector
- Matches our slip-on exhaust perfectly
- Stainless steel stepped header design for improved flow and longevity
- Hydroblasted finish with rust inhibitor looks great and turns bronze with heat
- Does not use factory heat shielding and should only be used with a slip-on exhaust with no catalytic converter
- Made in-house at our facility in the USA
- Extremely easy installation, bolts in like factory using OEM gaskets/mounting

- Header includes a new gasket where it meets the cylinder head
- Why the AA header over others? We design, build, and ship everything in house. Our header design has straight runners and goes around the frame rail like OEM which simply makes power. Other headers may look great and run inside the rail, but they will not perform well because of the sharp bends off the head.

Strechy and silky
Color: Grey Heather, Size: X-Large
Super stretchy and very silky feeling. It’s the same look at the lulu hoodie with similar material, but it’s different fabric. Very stretchy very silky

Color: Light Grey Heather, Size: Large
I love this hoodie, if you're thinking about buiying, just do it. Watch the price if you can for a while as this brand tends to go on sale frequently. I got it for a great price and its well worth it. I really like the look and quality, most importantly the price!

Great style and comfort
This is a fantastic sweatshirt! Made from a high quality fabric this shirt doesn't even feel like what you think of when you think "sweatshirt". It has a sophisticated design pattern and a great style perfect for golf or even to wear to the office in a casual tech company. My husband has done so and got many compliments and requests to tell him where he got it!
It is true to size, with a cut that fits a variety of body sizes perfectly. It is very flattering, comfortable, and soft. It just looks great.
It washes easily, stains do not set and neither do wrinkles. I intend to buy more of these in other colors.

Excellent Midlayer for Golf
Color: Light Brown Heather, Size: X-Large
My dad has been wearing this M MAELREG hoodie for about a week now, specifically during my early morning golf rounds where the temperature sits in the low 50s. The fit is true to size with an "athletic" cut, meaning it’s tapered enough to look sharp but has enough stretch and light enough to allow for a full shoulder turn during a golf swing. The cost is also a lot lower than some of the tech golf shirts out there. Overall this is a great shirt for golfing with an expensive look.
