Transform your GT4 RS’s exhaust note. Our X-pipe design gives the GT4 RS the same high pitched wail as the GT3 and it’s totally plug-and-play with the factory exhaust valve system so you can quiet down the exhaust using the factory PSE button.

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 cast X-Pipe to tie the two 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.”

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, quietting 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 6 WHP at 8100 RPM and 9 ft/lbs of TQ at 3500 RPM.

Good for smaller dogs too
Style: Tipsy Rosé
This dog toy states it's for large dogs (50+ lbs) but I bought it for my 12 lbs dog anyway, and Im glad I did because she loves it. Keeps her entertained. So much better than just handing her treats. When I hear it rolling across the floor I know she's busy and I dont need to worry about what she's up to. The hole is a good size for treats to fit in but she still has to work to get them out.

Long lasting high entertainment toy
Style: Tipsy Rosé
I was gifted one of these for my puppy and it is a fabulous toy. I put in dried liver chunks with at least one that is a bit of a tight fit so it drags out the experience for him. It’s highly durable, gets dragged around and pushed under furniture, and shows tooth marks but is still very effective. I also appreciate it’s easy to clean.
