707!

 

IMG_3320

707… We knew from the beginning that we’d have some fun working with the mighty Challenger Hellcat, but we just didn’t know how much… First impressions: wow. Power is definitely an understatement for this one. The face-melting acceleration of the Hellcat will change your definition of “fast car.”

We began prototyping the Roar Racing Super GT, a non-valved, no-nonsense, purists performance exhaust system. The full system features a dual 3″ X-Pipe which leads into a pair of Roar Racing mufflers specifically engineered for HEMI engines in order to provide maximum performance gains. The exhaust exits the rear of the car through our double-walled LeMans style quad tips. All of this hand built from T-304 grade polished stainless steel. Picture below:

The result of all of this is a tremendous improvement in power over the Hellcats original, restrictive exhaust system, as well an extremely aggressive sound that one of our Instagram followers described as “when your speakers can’t even create the actual sound because too much muscle.”

Numbers wise, this Hellcat will now be tearing up the asphalt with a newly found 29 horsepower and 35 ft/lbs of torque, at the wheels! Enough reading for now though, turn your speakers up and enjoy the video!

Lexus RCF and the MUSA Series

 

Our MUSA series by GTHAUS has been in the works for some time now, a project that has been kept silent while we patiently waited for a unique vehicle to head its debut. The 467-horsepower, V8-driven RC-F by Lexus was the answer.

Once directing our focus onto the RC-F, we set out to create the wildest, best performing, and most beautiful exhaust system on the market. Composed of a pair of E.V. controlled rear mufflers, and optional mid LSR pipe section, we believe to have achieved just that.

Pictured below is the GTC (EV Control) variant which we’ve installed on the car in the videos. This system is equipped with our 4x120x80mm oval exhaust tips (4x102mm round is also an available option). If you take a closer look at the mid LSR pipe, you will notice the velocity chamber in the center. This velocity chamber highly increases the flow of exhaust gases, much more than any traditional X-Pipe would.

From the factory, the largest downfall of the RC-F were its power-robbing secondary catalytic converters and inadequate diameter piping channeled into its highly restrictive rear mufflers – all of which we’ve taken care of. Our GTC (EV Controlled) rear muffler section, paired with our optional mid LSR Pipe (with velocity chamber) unleashed the full capability of the new Lexus, showing improvements of 46 wheel horsepower and 19 wheel torque (ft/lbs) on our Mustang dyno!

Meisterschaft for the new BMW X5 35i!

With the new X5 release from BMW, we immediately jumped on the 50i M-Sport due to the twin turbo V8 laying under its hood! With that done, we’ve shifted our focus to the more practical X5 35i, housing BMW’s brilliant N55 engine (3.0L I6 Turbo).

We like the N55. We like it’s liveliness and its substantial power output. More importantly though, we love the sound it produces when paired with the right exhaust! So, we brought the right exhaust into existence.

Held to a standard of perfection, the Meisterschaft exhaust system is constructed using T-304 grade stainless steel and is TIG welded completely by hand.

As the X5 is more commonly a daily driver than anything else, we had to accommodate both luxury and sportiness – resulting in two main variations of exhaust which are well known under the Meisterschaft brand: GTS and GTC.

IMG_2626

The Meisterschaft GTC (EV Control) is the easy choice here as it delivers the best of both worlds: luxury & sport performance. Our electronically controlled variable chamber (E.C.V.C) technology allows us to replicate the stock exhaust sound in closed mode, which is subtle and quiet but has faint sporty tone when you really get on the throttle. In open mode however, it is smooth, sporty & aggressive.

IMG_2568

We also offer the Meisterschaft GTS, the GTS is more conventional and produces an aggressive note 100% of the time, not featuring a valve control function.

The unit we’re introducing now features 2x102mm Round Split tips on both GTS & GTC variations. The 102mm, or 4-inch, exhaust tips fit freely into the rear bumpers exhaust openings with a perfect gap all the way around.

IMG_2758

We are also currently working on a 4x102mm Round Split version, for those who are looking for a very aggressive look at the back of their car. The 4x102mm will be introduced at a later date.

With our Meisterschaft axle-back installed, the car peaked at 250 horsepower on our all-wheel-drive mustang dyno, this was achieved with the GTC (EV Control) unit in the open position, making a total peak power gain of ~20HP and ~23ft/lbs of torque. In the closed position we saw 228HP and 236ft/lbs. So if it’s performance you’re after, open up that valve!

All in all we are very happy with the results of this new X5 35i. It sounded great and made excellent power once equipped with a Meisterschaft exhaust!

GTHAUS at the SEMA Show 2014

IMG_9261

This year at the SEMA Show, Meisterschaft was everywhere! From our own displays to clients cars and more. In this post we will share with you some of Meisterschaft and Roar Racing equipped cars we caught at 2014 SEMA Show.

In the above photo, at the Nexen Tire booth was our very own BMW F80 M3. In-depth details of the build can be found in our previous blog post titled ‘The Road to SEMA 2014’, however the vehicle featured a full chrome wrap, Meisterschaft Titanium GT2 Package exhaust system, and a set of 20″ forged duo-block wheels – an original design by GTHAUS.

Our brand new 2015 S63 AMG Coupe had also made the long journey from Chicago and was displayed at the Savini Wheels booth in the south hall alongside several other Meisterschaft equipped cars.

The latest addition to our American Roar Racing line, the muscle division of GTHAUS, was our GTC (EV  Control) exhaust system for the brand new C7 Corvette, displayed beautifully on the wide body project below by Prestige Marketing and Savini Wheels.

Impressive Wrap, a prestigious wrapping company based out of California built this M4. It is one of the first BMW M4’s to be fitted with a Liberty Walk wide body kit and was topped off with our Meisterschaft exhaust system!

IMG_9282

Lastly, at the Savini booth, was an old friend almost unrecognizable. Here is a shot of our former BMW E92 M3 Widebody, completely re-worked by Prestige Marketing but still running our Meisterschaft GTC (EV Control) exhaust system!

Venturing out of the south hall, along the apron of the building was a G55 AMG that was built by Auto Tech Interiors that ran our Meisterschaft GTC (EV Control) with our signature Hexa-Tip setup!

Check out the gallery down below for some additional photos!

SEMA 2014 turned out to be a great time. We’d like to thank all of our dealers and fans that dropped by to say hello during the show and we hope to see you next year!

The Road to SEMA 2014

IMG_0137

We had a great time this year at the SEMA show and we hope you did as well, it is with somewhat of a relief that we can say SEMA 2014 is over! After several long weeks and late nights spent at the shop we completed our show cars within some ‘Mission: Impossible’ type deadlines.

From home, this time around, we brought two of our own: a brand new BMW F80 M3 dressed in black chrome which would be displayed at the Nexen Tire booth, and the all new S63 AMG Coupe from Mercedes-Benz which would be shown off by Savini Wheels in the south hall.

 

The F80 M3

Being a SEMA car, we had to outfit our M3 with only the best. We went with our full Titanium Meisterschaft GT2 Package exhaust system at the rear, with our complete turbo-back 3” cat-less downpipes, and optional single 90mm LX pipe, the end result was incredible!

We then fitted the M3 with our very first, very own wheel. Featuring forged aluminum duo-block construction, we are able to achieve aggressive concave without sacrificing structural integrity. Additionally, the bolt pattern has been placed on the spokes themselves, eliminating any excess weight.

Finally we had to make her shine. We went with a full black chrome wrap. This was a timely process, but turned out beautiful and was completely worthwhile in the end!

The S63 AMG Coupe

We received our brand new 2015 S63 AMG Coupe just 1 day prior to loading. Working around the clock, we gave the new car a full detail, completed the graphics, and fabricated a completely custom exhaust setup to roll into the SEMA show with.

Once the cars were completed, loading them onto the transport trailer and seeing them off was a great feeling, we made it!
