Re: Exhaust System
Sorry i have no evidence to provide but rest assured the exhuast is one of the best 'bang for buck' modifications you can do.
OK, so no evidence but a rough idea - my car is good for about 105rwkw in stock form. It was dynoe'd with a cat-back (note - no extractors) and got 115rwkw. This was some time ago, getting a bit more outta the ol' girl now
A good exhaust with extractors should release AT LEAST 10kw from the engine. The sound is just an added bonus.
Fuel consumption should be better when cruising. But of course you wanna hear that growl so economy-style driving goes out the window, lol. How's your self control?
