The shorty pipes that attach to the LS3 Exhaust Manifold do not provide clearance below the floor for the rest of the exhaust system even with the 3/8" spacers added. I have shortened the TKX transmission mount spacers (down to 0.875 from 1.1 inches) but am now at-3 degrees down limit on the output shaft so cannot lower transmission further. Is there any other solution other than having a custom muffler shop make new shorty pipes?
