jonnyboy you have to order "754813" otherwise you will not get any extra performance and the sound will be a lot less.The system is designed to work with the 2 exhausts and the centrer section(754813) and it does sound very nice.My wife drove past me in my car and it sounded like a 308 Ferrari( a 1980 "s car).The car is not lowered,it has 18" wheels on it.You will need springs specifically for a159Q4 and shocks as well,the car will look better but you will lose comfort and wear the inside of your tyres out faster because the camber settings are changed when you lower the car.(you get more negative camber)
