Ideal for enthusiasts seeking a more conservative sound enhancement, this muffler is particularly suited for those running cat bypass or sport cats who want to avoid excessive noise levels. At low RPMs and during cruising, it delivers a refined, deep tone that remains discreet. Designed to comply with Germany's stringent urban decibel regulations, this is a German Edition muffler built for subtle performance.
DesignTek offers a wide selection of mufflers to suit diverse preferences, ranging from mild, street-friendly options to exotic-sounding sport mufflers and high-intensity race mufflers. The DesignTEk Edition 987.1 street muffler stands apart from conventional aftermarket designs.
Crafted from German V2A - X5CrNi18-10 - 1.4301 (T-304 L) lightweight stainless steel, it incorporates advanced features like double perforated sound absorption tubes in a trapezoidal pattern with variable perforation diameters. This design effectively isolates and dampens unwanted drone frequencies. Additional stamped ribbing on the outer shell further reduces unwanted resonance, achieving superior acoustic performance.
Unlike traditional baffle plates, this design minimizes back pressure, particularly at higher gas velocities, resulting in improved throttle response and enhanced performance across the rev range. When combined with software tuning, upgraded intakes, or additional exhaust modifications, the benefits are even more pronounced.
This muffler offers a subtle factory motorsport sound, making it an excellent choice for those who desire a conservative sport tone. Its reduced decibel output ensures it remains suitable for vehicles equipped with sport cat or cat bypass headers, maintaining an enjoyable sound without becoming overly loud.
Each system undergoes rigorous testing for exhaust gas flow, thermal durability, resistance to cracking, and long-term reliability, ensuring exceptional quality and performance.
Features:
- Increases by 9 HP and 11 TQ
- Weighs 43 lbs. (19.5 Kg)
- German V2A - X5CrNi18-10 - 1.4301 (T-304 L) stainless steel for improved durability
- Includes dual round 3.5” (90mm) tips
- Direct bolt on replacement
- Increased decibels with an exclusive, exotic motorsport sound
- Software programming is not necessary

These simple U/J pipes remove the mufflers that are tucked up in the rear quarter panels. Why the reason for these I do not know. Typically in the past we either see a main centre muffler or 2 mufflers with catalyst pipes. So this was the first simplest part to change out. Keeping the same diameter for a perfect OEM replacement, these pipes are straight through which not only eliminates any muffler packing or baffling, but also the weight. Each stock muffler weighs approximately 15.6lbs. The Designtek Secondary Exhaust Muffler Bypass Pipes are about 3lbs each. Now eliminating restriction, we have also saved about 25lbs off the rear end. Because this part still retained the factory headers with cats and the factory center muffler, it added a slightly deeper tone to the exhaust but not a drastic droning change that a full exhaust could. Upon revving the car out stationary and on the dyno, you could hear the tone change nicely as you past the 4000rpm mark.
Garage Notes: The pipes sometimes rub on the heatshields causing a resonation through the car. This can be sorted by redressing the heatshields but isn't a straight forward bolt up and go replacement.
The sound its self is quite impressive and very sporty from the outside but to drive causes a pretty bad droning sound under normal driving conditions. This exhaust peaks at 101decibels
According to the factories dyno test, the secondary muffler bypass pipes really start achieving performance from 3700rpm all the way to redline. With a baseline test in 3rd gear and all wheel drive (have to for the dyno and no warning lights), the car made 344HP and 289ft/lbs of torque. Based on the ambient temperature, the factories Mustang Dyno, and 91octane fuel, this is about right considering the car comes with 400bhp. With the addition of our pipes, the car put down 358HP and 298ft/lbs of torque gaining 14HP and 9ft/lbs at the peak.
