Holley Blackheart Exhaust

[Gmachine1911]

My experience when doing the exhaust on my 68 Camaro with the Quadralink setup was that even the 2.5” diameter pipe had no room going over the axle. I ended up notching my trunk corners to get enough room. Mine is all 3” pipe but we did put some 2.5” up there just to see if the real estate was there before I notched the corners.
