Akrapovic Introduces Titanium HH 2in1 for Walz Hardcore Motorcycles


After the initial agreement in December 2011 between Akrapovic and Walz Hardcore cycles, we’re thrilled to introduce to you the Titanium HH 2in1 custom exhaust designed for the German jewels.

With more than 9 hp boost on the testing dyno, the Akrapovic exhaust will also add serious extra torque, making the Hardcore bikes ride and sound better, and not only look better.


The Titanium HH 2in1 is a 3-piece system: titanium alloy header pipes, a titanium collector and a titanium muffler sporting a carbon end cap. The dB-reduction piece can be removed if needed. The Akrapovic exhaust system can be equipped with an internal catalytic converter and a lambda probe, with a dummy plug for older models lacking this type of sensor.

With a 2.3 kg (5 lbs) weight, the new custom exhaust is extremely light, making your bike even swifter. The e1/e24 homologation is not available, with EG-homologation in progress. Walz Harcore Cycles claims a single certificate of exemption could go for registering a bike equipped with this exhaust, but they can offer no guarantees.


The Akrapovic Titanium HH 2in1 exhaust system for Walz Hardcore bikes retails for € 2,980 ($3.985).

Daytona Twin Tec Twin-Tuner2 For Harley Davidson

Harley® owners looking for improved motorcycle performance can easily add horsepower and improve throttle response with a simple and low cost modification. The Daytona Twin Tec Twin-Tuner2 Fuel Injection and Ignition Controller allows you to easily adjust your fuel injection to match the requirements of your performance parts including camshafts, free flowing exhausts, and low restriction air filters. It has all the features of the original Twin Tuner and includes ignition timing control capability. The simple plug-in installation and set up takes only minutes and requires no splicing or bulky interconnections. The unit is completely encapsulated and impervious to moisture. With a low 1/2″ profile, occupying only a fraction of the space required by competitive products, you won’t have a problem finding a place to mount the unit.

The user interface consists of up/down pushbuttons and bright daylight readable LED display to select and change the fuel trim and spark retard in the RPM and throttle position ranges required by most applications. The Twin-Tuner2 also has an advanced mode, where you can use the optional USB Interface and PC Link Tuner software to make precise fuel and spark retard adjustments as well as making independent adjustments to the front and rear cylinders. If you have created Dynojet Power Commander Files for your applications, you can enter the same values into our tables because the PC Link Tuner software uses the same RPM rows and throttle position columns.

The Twin-Tuner2 works in combination with the Twin Scan II+ tuning aid, giving you precise tuning without the need for a dyno. Simply install the Twin Scan II+ and ride the bike. You can then download the air/fuel ratio corrections calculated by the Twin Scan II+ into the PC Link Tuner software.

*The Twin-Tuner2 is not legal for sale or use on pollution controlled vehicles.

The product focus of Daytona Twin Tec LLC is electronic fuel injection and ignition systems for Harley-Davidson® motorcycles. For more information on Daytona Twin Tec, call 1-386-304-0700, or visit www.daytona-twintec.com.
