Grunt Exhaust Manifold for 2015-21 250
The "Grunt Exhaust Manifold" exhaust manifold has a much better shape than the Large ID stock manifold. It bolts on in munutes and gives you throttle response and pull you can easily feel, from idle to past mid. Works with all headpipes and needs no Fuel tuning. The high temp O-Rings ensure perfect sealing to the head pipe and it's made of stainless steel.
