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.
