i am looking for ways to get more flow and horsepower and im looking in to a dual exhaust and i took it to a shop and they told me to look online for a two-tip suitcase muffler and they noticed that it already had a place cut out for a dual just not into the bumper so i need another bumper to fit a dual exhaust. everyone tells me to look online but i cant find any of this

the best solution is: sell it and buy the same one, just take the 1.8T engine, this engine is the finest product from vag concern. then go to your local car tuning company and set up the electronic turbine settings, you will easily get some 40-50 horsepower for not much money.
