Hi Guys,
I have an X reg VW Polo. Only a 1.4, but a very quick car. It is my first car (I'm 17). Basically, I've sorted the sound system, allows and D-badged it. I'm looking to buy an exhaust. I've seen a Sportex exhaust system, it comes with a race tube. My question is, do I need a race tube? and what difference does it make to the car?
Thanks:driver:
