Your Performance Edge In Racing - SuperTrapp!

SuperTrapp’s proven performance on the track has made it a standard in the racing world for decades.

Most of the riders (70 percent) competing in the AMA Progressive Flat Track Series, including Mike Hacker, 2001 National Champion Joe Kopp, 2003 FUSA Champion Bryan Smith, Bryan Bigelow and Willie McCoy use the stock SuperTrapp 750 Megaphone Series. Retired flat trackers Steve Morehead, Jay Springsteen and Scott Parker also used SuperTrapp products during their legendary racing careers.

SuperTrapp is the official exhaust of the AMA-sanctioned Xtreme International Ice Racing (XiiR) Pro Tour, with every racer using the 4-in. Megaphone External Disc Series to provide the extra burst of low-end horsepower and torque needed for short-track ice racing. Anthony “British Bulldog” Barlow has used SuperTrapp systems to power him toward three World Indoor Ice Speedway Racing Championships.

SuperTrapp is the main sponsor of Ton Pels, one of the most experienced European Drag Racers, and his Zodiac Drag Race team. Ton’s Top Fuel Harley Davidson is, and has been for many years, the fastest and quickest normally aspirated motorcycle outside the United States.

Kerker power has delivered such champions like Eddie Lawson, Wayne Rainey, Pro-Star 600 SuperSport Keith Dennis and has powered such riders like Mike Hale and Tom Kipp. Kerker is also the official slip-on exhaust of the Starboyz sport bike stunt team, which inspired the new Kerker Starboyz series slip-ons for late model sport bikes.


I’ve been using SuperTrapp for 25 years and it’s always great to work with a company that stands behind their product. Most of my personal bikes have a SuperTrapp system and even my Road Glide has a 2:1.

SuperTrapp exhausts are top-notch for performance. I always use the tunable systems that allow you to tweak your exhaust’s back pressure to gain horsepower and torque where and when it’s needed.

I have been building engines for 27 years and have been involved with ATV racing since ‘83. Four-wheeler racing was limited at the time and there were only a few shops that made racing pipes. I would take a SuperTrapp exhaust and adapt it to the custom four-wheelers we were building. When the production ATVs came along, I continued to use SuperTrapp on the new models. Pipes are now more important than ever. With the new production units, one of the easiest ways to gain additional power is through the exhaust system. The exhaust system accounts for 60% of the additional horsepower boost that performance race shops can find. There are a lot of quality exhaust systems. But there are only a few that give a significant boost in performance. SuperTrapp is in that category. It’s a quality product.

A lot of the attention that an exhaust system gets comes from the sound that it makes when it’s going around the track. A SuperTrapp exhaust system has that impressive sound. What’s nice about a SuperTrapp is that you have the option to tune for decreased volume if your particular riding area requires it. It’s a great muffling spark arrestor.

We try all the competitive exhaust products. If there is a better one we’ll use it. But, it’s pretty obvious when you go out to the track and see everyone is using SuperTrapp. There must be a reason for that. That’s how racers are. If it’s a better product, we’re going to use it.

The biggest thing about SuperTrapp for a racer is the total tunability of the external disc system. It lets you tune the exhaust to make the bike easier to ride. And, the durability is second to none. The stainless steel design means it’s not just some aluminum can.

- Bryan Bigelow, '01 SuperTrapp Supertracker National Champion

I have been using SuperTrapp exhausts since I turned professional in 1989. Everyone said SuperTrapp was the best. So, that is what I started using. I have been very happy with SuperTrapp ever since. I have tried competitor’s products, but the SuperTrapp exhaust is just so tunable for each situation that I always end up going back to SuperTrapp. On fast tracks, you want more horsepower and SuperTrapp works perfect for that. Sometimes there are situations where you want to tune the horsepower down because it makes the bike easier to ride. Overall, the tunability is awesome.

The stainless steel design is a big advantage. A SuperTrapp lasts longer than some of the competitors that don’t use stainless steel. The SuperTrapp looks better and keeps its looks for a longer time.

- Willie McCoy, AMA Flat Track Racer
Harley Davidson Sportster Performance Champion in ’99 and ’00 and 15th in the ’03 AMA Progressive Insurance U.S. Flat Track Championship Series.

I have been working with Jay Springsteen since ‘93. When I started, we were using competitor’s pipes that we weren’t happy with. I gave SuperTrapp a call and they have been taking care of me ever since.

The tunability of a SuperTrapp offers a big advantage for our race team. Using the SuperTrapp 2:2, I can tune the bike for any track. The power delivery is the key when tuning the exhaust. With SuperTrapp, I can determine where the hit is in the motor and whether I need to take it out of the bottom, put it on top, or have it everywhere. SuperTrapp also outperforms the competition when it comes to maintenance. They’re stainless steel. They clean up nice and look great all year.

- Joe Bisha, Mechanic for Jay Springsteen. One of the top five tuners in the sport today.

A lot of companies say that they do one thing and they do it well. With SuperTrapp Megaphones, they really do those well.” SuperTrapp is probably the best kept secret in performance exhausts.

- Joe Brown, Vintage Racing Tuner for Jay Springsteen

SuperTrapp has really stood by racers over the years. In the dirt track community they have helped more racers at the National level than any other company. Their stainless components are so durable from a chemical standpoint that nothing really fazes them.

- Jim Wagner, Sales Manager, Doc’s Harley Davidson

I have worked with SuperTrapp off and on for the last ten years. The tunability of a SuperTrapp is a big advantage. It really helps with track tuning. When racing on a slippery track, I’ll put big end caps on and detune the bottom end. It makes the bike easier to ride in those conditions.
