Fabspeed Shelby GT350 / GT350R RENNKRAFT™ Modular Sport Catalytic Converters (2016-2020)

These modular Shelby GT350/GT350R RENNKRAFT® Sport Catalytic Converters are the perfect solution for any street and track focused GT350/GT350R owner. Adding significant power and sound, you have the option to go with ultra high-performance HJS German Imported HD Catalysts or our modular design featuring a quick release V-band connector allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass “straight pipes” for all out competition race track use (patent pending). RENNKRAFT®, translated from German is “race power”. These unique Sport Catalytic converters offer true street and racetrack functionality in an innovative precision engineered package. 

SOUND:

There isn't much to improve on the intoxicating sound of the flat plane crank 5.2 liter V8 - until now. Adding a significant increase in power, tone, and sound, these high flowing RENNKRAFT® Sport Catalytic Converters give unrestricted flow with NO CEL (Check Engine Light). Equipped with our 200 cell cats, you will get a more aggressive and raw exhaust note. Higher frequency tones are more defined, and deceleration burbles are more robust and transparent. The volume isn't overbearing, but the sound is very aggressive on WOT (Wide Open Throttle). With the stock muffler in place, there is no drone what-so-ever.

POWER:

After extensive dyno development we found that using the highest quality HJS German Catalysts offer the most power across the entire power band. With no tune, compared to a stock car we gained 21 whp and 27 ft/lbs of TQ at 7100 RPM with Sport Cats. That's a gain of 25 HP at the crank! See our untouched dyno graph above for more details.

NOTE:

Why no harmonic balancers like the factory downpipes? After careful engineering and thousands of miles of testing, we have found that the harmonic balancers are not necessary for our Sport Cats. This is because we are using a thicker gauge of tubing than the factory, which changes the harmonics of the pipe and improves durability.
