Upgrade your Porsche 718 GT4 RS with the Fabspeed Titanium Valvetronic X-Pipe Cat-Back Exhaust System. Experience a 15% increase in power and a deeper, more aggressive exhaust note. Made from lightweight titanium, this system offers improved performance and weight reduction. Enjoy full control over your exhaust sound with the valvetronic system.

Our design process started with 3D scanning the entire OEM exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we decided to use our signature investment cast  X-Pipe to tie the  FLAT 6 engine's two separate Right & Left cylinder banks together for exhaust scavenging and to defeat resonance. We also went to great lengths to eliminate drone on this exhaust, utilizing helmholtz resonator technology to cancel out unwanted frequencies that “drone.” Porsche GT4RS and SPYDER RS owners and shops- the FABSPEED GT4RS rear valvetronic is 100% guaranteed to be the best sounding, most reliable and most powerful system available. 

SOUND:

Wondering why your GT4 RS doesn’t have the same high pitched scream of the GT3? Our Valvetronic X-Pipe is the solution! Our X-pipe design merges the two exhaust banks for an intoxicating 9000 RPM symphony. Even though this system will net you a significant increase in volume over stock, the valved design allows you to control the volume with the factory PSE (Porsche Sport Exhaust) button, quieting the exhaust note for a drone free driving experience. 

POWER:

Comparing our development car equipped with our Over Axle Link Pipes, our Vavletronic X-Pipe added +7.5HP (+6.2 HP at the rear wheels)  at 8100 RPM and +11 ft/lbs of TQ at 3500 RPM. WE designed and DYNO developed multiple systems BEFORE we settled on the very best system in terms of sound and horsepower. Trust Fabspeed with over 30 years or experience!

Good Quality Replacement for Lexus
Style: BE-285 1-Pack
Was a perfect fit for my 2016 Lexus NX200t. No tools required. Total of 5 minutes to install. Airflow is good after replacement and the activated charcoal seems to make a difference in reducing any smells from outside. Recommended.

Economical, easy to install, and does the job!
Style: BE-182 1-Pack
First, depending on your car model, replacing your cabin air filter is VERY easy. With that out of the way, the shop wanted to charge almost 65 dollars to replace my cabin air filter. Decided to just buy one and do it myself. The only downside of waiting is that the air inside the car is not as fresh/clean when you're running your air. Anyways, you can usually get these kinds of filters between 20-45 dollars from auto part shops depending on the brand and features. I've used this brand and filter for the past 3 replacements on my car and they last just as long and filter just as well from my experience. No issues installing, and does in fact do a good job of filtering outside odors. Highly recommended for the price!
