Tailgunner Exhaust Systems
4. For the install the stock clamp was re-used after being inspected, then slid onto the Mach II. Next, the pipe was installed onto the header pipe and the exhaust clamp was tightened. Then the 1/2-inch hanger bolts were installed and the pipe was wiped down to clean any fingerprints. | 
5. After the dyno run, the bike reached 62.9 hp and 73.8 lb-ft of torque. A slight gain; not bad for a slip-on with no tuning. | 
6. We placed the bags back on the bike to see how they looked. Nice, clean, and much cooler than stock, and for some people that's all that matters. But for the guy who is looking for something a bit more, Tailgunner has something for him as well. | 
7. The B-52 Jet-Pipes were tested next. The bike was placed back on theDyno and the Mach II was removed and replaced with the Jet-Pipes. The B-52 Jet-Pipes feature a solid billet polished thrust-cone nacelle. You can also get them in chrome, polished, or in a stealth black finish. They come complete with high-bypass ventilation holes for styling. MSRP $795.00 as shown here. |  | 
8. The B-52 Jet-Pipes were bolted on, wiped down, then run on the dyno. Once the bike was up to speed and temp, the numbers were 62.4 hp and 75.7 lb-ft of torque. |
9. Just like the Mach II, it was as easy as one clamp and two bolts per pipe to install. | 
10. Next were the Gunships with their spinning turbines. The faster you go, the faster the barrels spin. As with all their pipes, these are handcrafted in America and are triple-chrome plated with show-quality finishes, and are available with or without full-length baffles. |  | 
11. Once the B-52s cooled down, they were removed and the Gunships were installed. They slipped right onto the header pipe; a great fit and easy to install. Then both the 1/2-inch hanger bolts were installed on both pipes. | 
12. The pipes were installed and the bike was fired up. At first we noticed that one side was spinning faster than the other. The left side was moving, but not as fast as the right side. We realized that we needed to get a set of true dual headers. True dual headers provide improved performance, equal exhaust pipe flow, and allow for even barrel rotation. | 
13. One more dyno run and the Gunships pushed out 63.6 hp and 75.7 lb-ft of torque. The sound was good, pushing a deep, ripping sound on acceleration, and throughout the pull it remained heavy and throaty. Anyone with some basic tools could install any of these muffler in less then an-hour and have an exhaust that's cool looking with good sound and some power gains.
