I disagree. The Borla systems that I have heard are obnoxiously loud compared to the Corsa systems, and tend to get the attention of law enforcement officers. The Corsa setup sounds fantastic, and only gets loud when you start to really crowd the throttle.
Itís all subject to opinion when it comes down to it. Personally I despise the Borla systems, especially on the C6 (the design of the system just looks cheap imo, like they slapped a pair of F-body Flowmasters together, which can't be that light either). As for the sound of Borlas altogether, I have to agree they are very loud and obnoxious (especially at the lower rpms) with a very bassy sound that takes away from the natural crackle of an unrestricted V8.
I love the Corsa because it doesnít take away from that NASCAR crackle, but others may think that sounds cheap as well. That "natural" unrestricted V8 sound has no tuned tone to it, which others dislike. Most compare the sound of a Corsa to that of a diesel engine (especially at idle) and I would have to agree somewhat. In the end However the tone I always look for is that "race" tone, and you rarely if ever hear NASCAR or other V8 racecars for that matter sounding like a Borla so thatís how I come to terms with it.
Best exhaust for the C6z imo is the B&B Fusion. Looks light, retains the stock valve system (which is so damn awesome!), and doesnít clutter the hell out of the rear end like some of the other systems out there. When I finally make the plunge into a C6 thatís the first thing I am throwing on!!
My friend has the 01Z and he LOVES his Borla. We get into arguments over what sounds nicer (I prefer my stock ti to his Borla, he hates the crackle that those systems make). Bottom line is this as I tell him, love the Chevy V8s but man nothing sounds better than a V8 Ford so we all lose in the end
