Now Introducing: Meisterschaft GTC for the new BMW M3/M4!


In 2008 when the BMW E92 M3 was first released, we developed the Meisterschaft GT and GT2 exhaust systems which became vastly popular due to their absolutely intoxicating sound and undeniable performance. Two years later, when the newly released Meisterschaft GTC (EV Control) systems began gaining popularity, we received numerous requests to develop a Meisterschaft GTC exhaust system for the beloved V8-powered E9x M3. Thus, we went back to the drawing board and created a system which was perfect for the daily driver. In open mode, the GTC system brought out an absolutely wild, exotic, and aggressive exhaust note with unquestionable performance from the 4.0L V8. In closed mode however, that aggressive sound would become tame and docile, but would still sing a beautiful exotic song to let you know that it was a Meisterschaft.

Now, 2014, the E9x chassis is no more, and the F80/82 M3 and M4 are here. So, it’s time to show our cards!

For the first time in history, BMW has placed a forced-induction motor into an M3, and also now, they have named the 2-door version of the car, the M4. But, with the number of doors and naming put aside, we set our focus on the sound of the brand new 3.0L twin-turbocharged S55 engine. We found the OE exhaust from BMW to be quite clever, and interestingly enough, it featured electronic valve control similar to our GTC systems we had been producing for the past several years. Clever as it may be, this did not mean we could not improve on it, which we did. A lot.

Achieving the aggressive exhaust sound, as well as the performance that we were looking for out of the new M3 and M4 was not an easy feat. Countless hours, late nights, and many prototypes along the way is what it took to get us to our three exceptional designs, each engineered to perfection for the true automotive enthusiast.

Today, with more to come, we bring you the flagship model. The Meisterschaft GTC, featuring 100% manually operated electronic valve control to provide the most convenience to the user. Aggressive when YOU want it, quiet when you dont.

Our electronically controlled valve system on the Meisterschaft GTC gives you the best of both worlds. With the valves in the closed position, the GTC system produces a sound that is comparable to factory, convenient for your daily commute or any other situation where you find yourself needing to ‘quiet down’ your exhaust. Open the valves and the fun begins. In performance (open) mode, the Meisterschaft GTC brings out the sound and performance of a true M car: aggressive, exotic, perfection.

Featuring dual 76mm (3-inch) inlet piping, our Meisterschaft GTC optimizes flow in performance/open mode to bring the most out of the twin turbocharged 6-cylinder. This unit is available with either our 4x90mm or 4x102mm Round Split Meisterchaft signature tips.

Looking for more? These are our optional full cat-back Meisterschaft Dual L.X. Pipes. This set of cat-back piping features dual 65mm cat-back piping into our high-flow velocity chamber and back out to dual 76mm piping for a direct connection to our SR pipes and rear muffler section resulting in a full bolt-on installation. Additionally, our Dual L.X. Pipe section is optimized for horsepower gain. In the near future you can also expect to see a single version of our L.X. pipe – featuring enlarged piping diameter and optimization for torque gain.

For the real enthusiasts looking squeeze the absolute most power out of their vehicles, we bring you these, Meisterschaft Cat-less Downpipes. These remove the primary catalytic converters allowing the turbos to breathe freely and work more efficiently, resulting in significantly increased power. Pair these cat-less downpipes with our full cat-back Meisterschaft exhaust and a tune of your choice, sky is the limit!

All in all, we found the new F80 M3 to be an amazing machine and we thoroughly enjoyed this development process. Make sure to be on the lookout for a secondary product release next week as there is more to come for the F80 M3 and F82 M4 from Meisterschaft!






The C7 Corvette meets American Roar Racing


Corvette C7-21


The next generation Corvette is here, and with it comes an entirely new line of American Roar Racing exhaust systems!

GM has really outdone themselves on this new C7 chassis. From the magnificiently sculpted exterior to the completely redesigned interior the new Corvette is a real beauty. The near 50-50 weight distribution of the chassis and all new magnetic ride suspension keep it nice and stable through any turn!

The part that we took most interest in however, is the 6.2L V8 that resides under the bonnet, churning out 460 horsepower and 465 ft/lbs.  of torque!

It was our task to harness the sound produced by the grumbly LT1 motor and transform it into an 8-Cylinder symphony, resulting in the most unique, exotic sounding exhaust system to ever be produced for the Corvette.

Corvette C7-13

GTHAUS is proud to present this all new American Roar Racing exhaust. American Roar Racing is the muscle car division of GTHAUS. Keeping things consistent with our Meisterschaft line, we use highly polished T-304 and T-316 grade stainless steel to produce our hand-made American Roar Racing exhaust systems. This is not limited to only the mufflers and tips, but the inlet piping, the hangers, and all of the hardware as well. The entire system, front to back, side to side, is manufactured with some of the highest grade stainless steel available on the market.

For the New Corvette Stingray, American Roar Racing offers the GTS (Ultimate Performance) and GTC (EV Control) which come standard with our signature 4x102mm Round Split tips.


IMG_4358 final

Included with the exhaust system is our cat-back LSR mid-pipe, which removes the restrictive secondary catalytic converters and replaces them with full cat-back 76mm (3-inch) piping with a crossflow section to provide maximum flow and improve performance.

IMG_4224 final

The American Roar Racing GTC (EV Control) brings you the best of both worlds, featuring an electronic valve system that allows you to control the volume of your exhaust via the included hardwire toggle switch or optional wireless remote. The valve system operates on a 12VDC power source and is controlled manually.

IMG_4330 final

The American Roar Racing GTS (Ultimate Performance) offers same iconic sound and performance as the GTC system in open mode. However, the GTS system does not feature valve control and thus does not have the convenience of ‘closed’ or ‘quiet’ mode.



Corvette C7-18

The new C7 Stingray was a truly exciting project for us and we enjoyed every bit from beginning to end. We hope this system brings you as much joy as it brought us the first time we ‘pushed to start’.
