Dynos can be altered very easily! I thinks it should be a lot more interesting to see some pre and after in gear times, for example a tipical 50-90 kph in 3rd and 4th gear.
The quicksilver increases are more utopistics than the milltek's, changing the muffler has always low effect on the output figures, even on turbo engines.
The stock exhaust is already pretty straight, especially when we think of the one on the R53 and it's tortuos design.
I'm investigating about the sizes of the stock exhaust, do you know what is the inside pipe diameter? |
