I've looked at some GTi's with Milltek, and it sounds sooo sweet! However, I do have some questions;
1. How much power will I gain from it?
2. Is it a BIG difference between Turbo Back and Cat Back? Thinking preformance wise and soundwise. If so, what are the difference(s) ?
3. What will happen to the fuel economy?
4. In Norway a full Milltek, mounted on the car, cost 1500£. A cat-back, mounted on the car, is 800£. What's the price oversea? ( I mean in the UK.. -_-)
Thanks in advance for the replies!
