I'm thinking of putting twin cats on my VT V6. I went to the wreckers and he had some twin cats off a VZ. would these be any use to me. Or are they different being an alloytec?
I'm pretty sure what your looking for is the VY Series 2 cats.
Correct, VZ have the most restrictive cats out of all the models
Just get another cat off a VT V6 and keep your other one as you will have to spend money with extra exhaust piping
