Sporty Pipes too Short

[JimV]

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?

There are several exhaust extensions out there, just google the diameter and length needed. You are correct, if that drive shaft gets too low it will hit the lower part of the chassis where it exits the cab. I am seeing this with raising the shocks in the back to get the nose down attitude I want without lowering the nose below 5.5 inches.
