Nissan Altima Header

These highly anticipated headers for the 2.5 liter Nissan Altima Coupe are ready for release after months of testing and development. The goal for these Nissan Altima headers was simple. Easy, bolt-on installation, good horsepower gains, and no check engine lights. The STILLEN engineers were able to meet these goals and then some.

These Nissan Altima headers are a very easy installation only requiring a simple modification to the B-pipes and extending the O2 sensor wires. Testing on a QR25 engine proved gains in excess of 10 wheel horsepower. A secondary slip joint is included with the kit which installs in the rear section of the factory secondary pipes and prevents any SES lights. Additional benefits are a nicely improved exhaust tone and improved looks underneath the hood.




About STILLEN Parts & Accessories

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.
