Drivers side feeds in from the bottom. Ya gotta snake it in with the rack dropped and feed the P/S lines through as shown. Kind of a pain... but necessary with the rack behind the motor instead of in front. The passanger side is cake... drops right in from the top.rock421 said:It will be nice if the headers go up from the bottom! I've done two sets on F bodys, and they had to go in from the top. Never figured that valve covers would have to come off to install headers. The Goat should be cake.

Headers... and full 3" stainless with X, high flow cats, and chambered "mufflers" ... with a single oval style exit in the stock location. We have found with this kit that the front and rear O2 sensors are not long enough for their new locations. I have new style 04 Corvette front O2 sensors on order for the fronts... same sensor and connector just much longer pig tail. I have extensions for the rear O2 sensors... which have the same flat4 style connector as the OLD C5 Corvette front O2 sensors.
This car will still have fully functional front and rear O2 sensors. It remains to be seen if the PCM pops a code or 2 due to the high flow cats. We'll see.
The stock cast iron manifolds have small ball joint style exits. The exits are smaller than a stock C5 cast iron manifold. Yet this engine in either car produces the same rear wheel results. Pretty amazing considering the amount of crimps in the stock GTO exhaust system. BTW, the crimps are there because of the exhaust systems proximity to other parts underneath the car.
