Installing an s480 under my factory vvt. What size down pipe for the s480? 4" or 5"?
And what size waste gate for the s480?
And what size waste gate for the s480?
Couple of twin questions
- Thread starter Js95gt
- Start date
4" down pipe is fine. What size ar is the exhaust housing? 1.32 doesn't need a gate, anything smaller should have one.
It is a 1.32 housing. Will it need a gate down the road? Let's say with bigger injectors an dual cp3s?
