You only like the sound of your stock exhaust because you've never heard the CORSA
exhaust "live and in person". Now that I have it, I couldn't imagine not having one.
They say it gives some performance gain, but I think it's minimal. I'm sure someone "techy"
will give you the exact gains on an aftermarket exhaust.
To me...an H2 looks tough, therefore it should sound tough too.
