Yes I have the Corsa exhaust on my 06 H3.

Pro's: Sound is good, kinda like a BMW straight six, but not a V8 rumble of course, not a ricer sound either. Normal freeway cruising is nearly as quiet as stock in the cab. Looks cool, stainless tips do not rust. A little extra power at high revs pulling long hills, etc.

Con's: At mid-throttle pulling long gradual grades, a bit of droning. Expensive at $850ish. For heavy wheelin you will need to have a muffler shop mod the tips so they can be removed, otherwise they might get damaged on departure.

Just my 2cents after several months using the Corsa.
