Sport exhaust - disappointment
Please be aware that this is the street legal version for the European Community markets, NOT the export version.
Sound has improved slightly, there is a deeper V8 growl but you have to have very good ears to be able to actually hear the difference. A huge disappointment, I expected more.
Of course it is better than the original sound but the difference is so minimal, not worth spending the money. Honestly. I still hope that the exhaust has to "burn free" first to get a decent sound and it might be the reason why it doesn't sound good right now. But at this point, immediately after install, it sounds slightly different and slightly louder thant the stock exhaust but not really impressive.
The good thing is: at high speeds, the exhaust has the same sound as the stock exhaust, there is no danger of getting annoyed by a loud noise. The wind noise still covers the exhaust noise completely.
To Dario: if you have the choice to go for the EC approved version and the Export version of the exhaust, go for the Export version. At this point, the street legal version isn't worth the money.
I also installed two BMC sport airfilters. The "breathing" sound of the engine has enhanced in the upper rpm band but don't expect a better engine sound.
A strange thing after the exhaust and BMC airfilter install:
under full acceleration, the boost pressure was always at 0.6 flat. Now the boost pressure gauge shows 0.7 bar. I don't know if it has something to do with the new exhaust but there is definetely a difference. I can't say if there is a performance increase.
Installed, the exhaust looks nice and it is fully compatible with the original exhaust pipes. Look at the picture.
I'm going to keep the exhaust for the next couple of thousand kms to see if it burns free and gets a better sound. I'll wait with posting a sound file until then, there isn't really much difference compared to the stock exhaust right now.
