Review on Flowtech 12540FLT Standard Headers by Joe Griffin

These manifolds look good but are very tight. You're close to the starter, you can get the original starter to work, but you'll probably have better luck replacing it with a smaller, low-gear aftermarket starter. If you want to use the original starter, install it on the vehicle first, then loosely put the head on it, and then tighten the starter cable, then install and tighten the head. You will also have trouble landing on the crossbar near the gearbox. And if you're using a C6 gearbox, you'll have to flex the shifter to connect the exhaust. Also what I haven't read until the market launch of original headers is delayed or an unnecessary header set, first run in the engine and then install the good ones, otherwise you might lose the warranty on it.
