V-Band clamps and flanges make for ideal tubing connections in exhaust applications, especially when the connection requires frequent disassembly. Used extensively in space vehicles and satellite launch systems, they have proven themselves in racing applications including high pressure turbo applications. The V-band connection gained popularity in CART racing and is the preferred connection for many turbo-housings. They are also an excellent choice for normally aspirated exhaust and for intake systems.
Compared with 2-bolt or 3-bolt flanges, Vband connections are typically lighter and are quicker and easier to take apart. They are also economical when compared to the 2- and 3-bolt flanges. The Vband connection also requires a small fitment envelope as compared with multi-bolt flanges. The design of the V-band clamp applies uniform force around the flange maximizing the seal potential of the flanges. The retainer angle, normally 40 degrees provides for an 8.6-to-1 mechanical advantage. In other words, when the V-band retainer bolt is tightened the clamp applies a radial force and an axial force pressing the flanges against each other providing an effective seal. Once tightened, friction between the flanges and V-retainer actually helps reduce the load on the bolt and clamp.

This exhaust makes the 135 sound and perform like a beast! Highly recommended
Excellent workmanship on fabrication.Install was very smooth,as fitment was good.i i have not put on my dyno yet,But seat of pants feeling from 3.5K RPM on up in the powerband is fantastic.Expensive and worth it.
Massive thank you to Vince and his Team for their support. Fantastic customer service and their NHB exhaust systems perform extremely well! Quality workmanship, great fit & finish and they support big power!
This is an amazing exhaust. My previous exhaust, which was custom fabbed for me to clear mid controls was restricting my output in the top end. With this exhaust, on the road, I can feel the difference about 5k rpm. My motor was built for top end power. This exhaust help achieve that without any sacrifice to the bottom end. It also looks amazing!
Easy install, great sound, and great performance, better felt low end torque and no felt loss at high rpm
No other exhaust work as good as this in bigger than stock engines!
Great look and super heavy sound are pretty well
Best made and sounding exhaust for harley!!! Period.
Top quality materials, a huge difference comparing to the other brands on the market , with no doubt I would to buy another one if necessary definitely 💯 would recommend it thanks Burns!!!
With Burns you get every bit of your money’s worth not only in the product but also customer service. To me if you are going to spend more than $1k, go with Burns because you aren’t going to get anywhere near the value with anyone else.
Excellent product! Sounds amazing and the fitment was easy. This product looks amazing and give the M8 a throaty sound!
This is a well made system, high quality materials and excellent welding. I know how much testing went into these, and they do what they advertise, make power.
