Here at GTHAUS, we are proud to release our full cat-back system for the brand new Infiniti Q50 Red Sport. The Q50 Red Sport embodies the sports sedan complex, with significant changes from its G37/G35 predecessor. With the Q50 generation bringing a new line of power plants, the Red Sport is the most powerful. As opposed to the G37/G35 naturally aspirated 3.5L/3.7L VQ engines, the VR in the Red Sport opts for lower displacement in favor of forced induction via twin turbochargers. This allows the new VR engine to produce 400 Horsepower and 350 ft/lb of Torque with a remarkably consistent Torque band. On our in-house Mustang Dyno, the Red Sport achieved 338 Horsepower and 330 ft/lb of Torque.

After running these stock numbers, we got to work engineering an improved exhaust system for the Red Sport. After careful examination of the stock system, we found significant bottlenecks that were having a significant effect on flow. The piping was diameter was far smaller and thus more restrictive than it should have been, and the mufflers were incredibly restrictive as well to overall flow. Our goal was thus to improve the sound of the system with the signature Musa series sound, while also improving the overall flow to evacuate heat more effectively and increase overall power production. The full system is divided into three parts; the rear muffler section, mid-pipe section, and front Y-pipe collector.

Each part can be produced in either stainless steel for day to day use, or titanium for the hardcore track build. Both offer significant weight reduction compared to the stock system. We decided to go with two offerings for exhaust tips, in similar fashion to the G37 systems prior. The two styles are 2x120x80mm ovals, and 2x102mm round tips. Installation of the system is a very simple process, due to meticulous construction of the system and superior build quality.

Upon construction and installation of our all new Red Sport system, we were excited to get it back on the dyno and see what kind of power gains we had made. With impressive increases of 15 Horsepower and 19 ft/lbs of Torque over the stock system, we were ecstatic with the results. Along with the power increases, we felt a noticeable increase in throttle responsiveness, as well as the signature MUSA series sound we all crave. Turn your speakers up and enjoy!!!

Lamborghini Huracan LP610-4 by GTHAUS

 

The Lamborghini name is one of the most iconic in automotive history, and the LP610-4 Huracan holds true to that title. Serving as the successor to the best selling Lamborghini ever, the Gallardo, the Huracan had big shoes to fill. It was the second we received, so by then we were familiar with the performance it brings. It checks off all the typical Lamborghini criteria easily- amazing looks, exceptional agility, and an outrageously powerful stock engine.

Driving the Huracan was an empowering experience. The Galdlardo was a great vehicle to drive, as it shared BMW mantra and feeling of the Ultimate Driving Machine- it felt like a natural extension of the body, like an arm or a leg. The Huracan shared this connected experience, however it was like as if a cybernetic enhancement was added. The interior was like any other Lamborghini, designed like a nimble fighter jet to be efficient, agile, and light.  Despite this, it was still a surprisingly comfortable car to drive- we took it into the crowded, hectic streets of Chicago numerous times without an issue.

While the Huracan was a great supercar from the factory, there was still plenty to improve on. Being our second Huracan, we were ready to push the envelope to make it one of the most unique packages we’ve ever created.

The redesign of the exhaust system was of course, the most extensive and awe inspiring changes we made. Lamborghini exhausts are always unique to create, due to the nature of them being mid-engine super cars. The lack of pipe distance means that passive heat transfer does not occur prior to the exhaust leaving the vehicle. As a result, we took extra time to analyze the heat transfer characteristics to ensure that the engine bay stays cool as possible under throttle, while still maintaining maximum flow using 63mm and 76mm piping. Increasing the flow means that the scavenging capabilities were vastly improved, giving significant power improvements along with the unmistakable, premium, Meisterschaft sound. Our dyno results showed an increase of 20 Horsepower and 14 ft/lbs of torque through the entire rev band.

The specific exhaust designed for this model was our signature GTC (EV Control) unit, actuated via the OEM drive mode controls. This means that the exhaust had two modes- one with the loud, powerful sound that you can expect from Meisterschaft while the valves are open- and the other a quieter, more passive sound for when that noise isn’t necessary. The system itself is a work of art, constructed from T-304 Stainless Steel (or Titanium) with meticulously crafted TIG welds. We replaced the OEM tips with the Meisterschaft dual wall LeMans style tips, (2x(120+102)mm Round Split) which were a better aesthetic fit for the aggressive angles of the Huracan’s rear bumper. It’s a dramatic change, cleaning up the looks of the rear end significantly.

Not only did we want the Huracan to sound great, we also wanted it to look great. The first phase of that was designing a beautiful set of wheels. The result was the Meisterschaft GT-1 Forged Duo Block with a Brushed Red finish. The front size we kept the same at 20×8.5”, but we increased the size of the rear wheels to 21×12” from 20×11” to give a slight increase in traction to further enhance the handling capacity of the vehicle. The look of these wheels was in a word, unique- one of the most interesting color combinations we’ve seen with the matte-black bodywork that really makes it standout from the crowd.

The final improvement we made was with the creation of a set of GTHAUS RAD-Dynamics Lowering Springs. These really improve the appearance of the car, maintaining functionality while giving it that mean look you would expect out of an exotic Lamborghini. It was lowered 1.5” in the front and 1.0” in the rear. While this might seem like a modest height to lower the Huracan, it provides a far more stable feel to the vehicle due to the lower center of gravity.

Our second Lamborghini Huracan turned out to be a huge success with all these parts put together. The car looked incredible, sounded incredible, and was far faster than the stock variant. This was as a result of our package of a GTC (EV Control) exhaust system, Meisterschaft GT-1 Forged Duo Block wheels, and GTHAUS RAD-Dynamics Lowering Springs. All installation was done at our in-house shop, Dream Werke.

Meisterschaft GTC and Super GT exhaust systems are available to order now. If any questions you have about this exhaust system were unanswered, please feel free to contact sales@gthaus.com or give us a call toll free at 1-866-278-1896 (Direct: 1-630-787-1600).

BMW F86 X6M: Meisterschaft GTC (EV Control) Exhaust

IMG_6280

We’ve recently completed the Meisterschaft GTC (EV Control) exhaust system for the latest BMW X6M, the F86. The familiar S63 engine in the new F85 and F86 X6M gave us a great basis to start with when developing this new Meisterschaft exhaust. All in all, we are ecstatic about the style, sound, and performance this new exhaust system has to offer.

IMG_8021

In addition to the axle-back GTC (EV Control) exhaust system, we’ve gone ahead and developed cat-less down pipes for the diehard power chasers.

Revving up the X6M with Meisterschaft GTC

In the video below, we rev up our Meisterschaft equipped BMW X6M through various RPM ranges in both open and closed mode to demonstrate the versatility of the Meisterschaft GTC exhaust system.

Putting the Meisterschaft to the test.

After putting our X6M to the test, we found that the Meisterschaft turbo-back exhaust system has given the car a very solid gain in horsepower, and especially torque. Our measured results were +32 wheel horsepower and +70 ft/lbs of torque.

All new Meisterschaft exhaust for the Porsche 911 Turbo S (991)

Here it is, the first ever Meisterschaft exhaust system designed and developed for the 911 Turbo! We begin our endeavor into 911 Turbo exhaust development with the all new 991 chassis Turbo S.

IMG_9621

We started off by gathering a baseline test of the 991 Turbo S on our in-house Mustang Dyno, finding some very respectable stock power figures: 457 horsepower and 454 torque at its four wheels. After baseline testing was done, it was time to begin disassembling the brand new beast so that we could study the imperfections of the factory system and make our improvements.

 

The Super GT

IMG_4068

Our answer is the ultra lightweight Meisterschaft Super GT, sporting 4 of our 102mm signature round split tips to give the back end an aggressive and complete new look. Our Super GT system replaces the overweight and restrictive OE muffler system with a 76mm high-flow X-Pipe engineered to provide maximum performance, especially once paired with our optional catalytic bypass pipes.

 

The Results

IMG_4234

With a monstrous torque gain of 57 ft/lbs, a horsepower gain of 17 hp, and a weight saving of 21 lbs, the Meisterschaft Super GT is an all around win. Not to mention the exhilarating sound of the twin-turbo flat-6 violently breathing through the new exhaust, and even occasionally letting out a flame or two! Turn the volume up and click play on the video below, listen for yourself!
