VRSF DP's do fit RHD 135's!

Hi all,

thinking of getting some VRSF 3" N54 catless Downpipes. I have a few questions;

How much real-life performance benefit do DP's add, considering I currently have Cobb Stage 1, so I assume I can go to Stage 2?

How much louder will the stock exhaust be with the DP's?

How much $$$ to have them installed?

Cheers
