This is Invidia Equal Length Race Exhaust Manifold - the perfect solution for those of you that want to take your horsepower figures to the extreme! With a 2-bolt up-pipe flange for upgrading to an external-style up-pipe or accommodating a rotated turbo setup, a 304 stainless steel construction and equal length design, plus a built-in O2 sensor bung and smooth bends, you can get the revved-up performance you crave. No more noisy boxer rumble, just an aggressive 4-cylinder race engine roar. Plus, it comes with new exhaust manifold studs for easy installation. So if you want to level up your ride, this is the way to go!

This Invidia header is the perfect pick for anyone wanting to go FBO. Ditching the OEM unequal length setup for this equal length stainless steel header is sure to make a power difference, not to mention make your ride look much better than the factory cast manifold.
