    The "Grunt" exhaust manifold has a much better shape than the large ID stock manifold. It bolts on in minutes and gives you throttle response and pull you can easily feel, from idle to past mid. Works with all head pipes and needs no fuel tuning. The high temp O rings ensure perfect sealing to the head pipe and it's made of 7075 aluminum, which is extremely strong.
