So I just had the header and downpipe bolted on with new OEM gaskets (LSJ GMPP manifold gasket) and I gotta say, it deepened the sound a bit, and it has more top end pull. I love it. I'll make an exhaust video after work tonight. Cat back is exhaust, but I'm thinking about doing a 2.5" custom axle back, or buying the one guys TC axle back to complete a full 2.5" cat back for cheap. I'm not sure if the pipe before the resonator is 2.5" also, I heard that is also a bottle neck but it looks all the same. And then maybe a muffler. Thoughts? Opinions? Comments? Thanks!
