So with having bigger cams, a ported head and the NX2 running 1.9bar the car shifts more air in and out, which is great. But and their always is this extra exhaust flow has increased the exhaust volume to roughly 115db, Exhaust fitted is the Ford Performance by Borla.
This exhaust comes with an additional 4″ silencer just after the down pipe, which is a Miltek 200 cell sports cat, which again allows more unrestricted flow. So the choice was made and a phone call to Tony Banks Exhausts (0113 279 8944) was duly done and it was booked.
The section highlighted was decided to add an additional silencer rather than increase the existing 4″ to 5″ as 2x 4″ would give a greater silencing effect.
