The vc has a dual 2 1/4 inch stock system which has 1 muffler on the pass side and one on the drivers side. Over the diff into a dual inlet outlet resonator
Im going to replace the 2 under the floor pan and potentially the resonator
What’s everyone’s recommendation

standard GMH V8 N10 dual exhaust that... went on all that had the dual exhaust option.

When they rotted out (as just aluminized mild steel) I replaced them with the VK GrpA
style system... large Y pipe from the engine pipes into one muffler (under rear passenger floor)
and a single axle over pipe to a ressie and single outlet

Sounded good and released a few hp too! .. especially if the standard manifolds also
got replaced with extractors (any brand)
