i have a custom 2 and a half inch and one muffler exhaust on my vy and im thinking of buying a vt calais or vx can i take the exhaust off my vy and put it on my calais???
It depends on the engine (V6 or V8 in the new one), and whether it's a wagon or not.
Thing to remember:
Most of the time sedans exhausts will not fit wagons (and vice versa)
Different engine type (e.g. ecotec/buick) and different cylinders will cause them not to fit
both ecotecs and both sedans
although there is a possiblilty the calais will be supercharged?
Aftermarket or L67 Supercharged? Both should bolt straight up. With the L67 most of the differences are in the engine or on the supercharger. But a single 2.5 still wont be great for that motor. It would be better suited to a 3" or dual 2.5"
If the VY is a series 2 it won't fit. If the VT/VX is factory S?C it won't fit.
