As soon as the Nissan Cube’s began to hit the streets here in the US, we knew these fun little cars would spice up the Mini-MPV market, and STILLEN went to work in our R&D department to develop some bolt-on performance items for the enthusiasts looking to take their Cube to the next level.

2009 2010 Nissan Cube Intake System STILLEN

The STILLEN Hi-Flow Intake System for the Nissan Cube features bolt-on installation, removes the factory baffling and creating a direct intake air path.

STILLEN is proud to release something we’ve been developing and fine-tuning for quite some time, our Secondary Cat Delete Y-Pipe for the Nissan GT-R!

The factory equipment this replaces contains two flow-robbing cats and weighs in at a hefty 30.25 lbs!  Our new Y-pipe replaces those cats with polished 304 stainless steel resonators and drops an astounding 47% of that weight, coming in right at 16 lbs.

STILLEN GT-R Secondary Cat Delete Y-Pipe

There is a lot of power held back by the factory exhaust system on the Nissan GT-R. By eliminating the factory catalytic converters, STILLEN has successfully improved flow, creating power gains as well as dramatically improving sound.

STILLEN GT-R Secondary Cat Delete Y-Pipe Flanges and Flex Joints

Additional info from the STILLEN Product Page:

Catalytic converters are not only very restrictive to the exhaust flow and performance, but they also act as mufflers, greatly reducing the sound that enthusiasts desire.

This Secondary Cat-Delete Y-Pipe System is TIG welded and constructed out of polished 304 stainless steel with laser-cut and CNC machined 304 stainless steel flanges.  The resonators themselves are also TIG welded, polished 304 stainless steel.

To allow the exhaust system to flex with the movement of the engine, yet stand up to the heat and flames coming off of the turbos, we have used nothing but the best turbo specific flex joints on this application.  Under hard driving, flames will travel through the exhaust system, and only turbo specific flex joints will stand up to the heat generated in those circumstances.

These parts are currently in production, and will begin shipping soon.  Make sure to get your order in now before the first batch sells out!


• Lightweight Materials – 47% Lighter than factory
• Increased Performance
• Race-Car Like Sound
• Polished 304 Stainless Steel – Lifetime Warranty

STILLEN GT-R Cat-Back Exhaust System

STILLEN is excited to announce the release of our premier Nissan GT-R Exhaust System.  After numerous systems were designed, fabricated and tested; Steve Millen selected this configuration as the one to put into production.

Meeting all of his criteria for power, sound and appearance this cat-back system uses 304 Stainless Steel, is TIG welded throughout, 27% lighter than stock (30 lbs versus 41 lbs for stock) and results in an aggressive (but not obtrusive) tone.

Additional info from the STILLEN Product Page:

STILLEN is proud to offer the premier exhaust system for the 2009 Nissan GT-R. After many different styles and months of development Steve Millen and the engineers at STILLEN have come up with an exhaust system that offers increased performance, race-car sounds, unmatched quality and ‘work of art’ appearance.

This exhaust system is constructed out of high luster polished 304 Stainless Steel. During the production process the rear exhaust components are polished five times to ensure a brilliant finish and to make sure that every part of the exhaust exudes excellence.

To ensure superior quality the exhaust is TIG welded by hand and the weld ‘burns’ are left to maintain the race car heritage and look of the Nissan GT-R.

The exhaust has been tested and tuned to offer superior performance and sound while offering a reasonable price. This exhaust comes with a lifetime warranty and is supported by years of racing experience from the experts at STILLEN.

These parts are currently in production, and will begin shipping shortly. Make sure to get an order in now – don’t miss out!
