I have had a blitz stanliess Nur-Spec R exhaust fitted onto my YRV turbo for the past 8 months. And I could do with getting feedback from other owners who has had/has this mod. I know that since having the exhaust fitted I have come across the dreadded Fuel cut issue where the car now overboosts and the ECU thinks this isn't normal and backs off the power causing the hitting the brick wall effect But as of late I swear the exhaust is getting louder like it's blowing from somewhere but cannot see any holes or places where the exhaust gasses are leaking from. And also when taking tight turns can hear the exhaust knocking at the rear. Looking at the fixings everything looks normal and each arm is connected etc.. Just wondering what other owners experiences are like?
