Let me also preface this opinion with the assumption that all the three systems I tested have equal performance gains as I do not have a dyno to test differences, but I would be willing to bet they are all within a few HP of each other.

All three systems had excellent build quality, but with the Corsa there were some installation enigmas that had me wondering "why in the heck did they engineer a band clamp there, could it not be the worse place to try and tighten". The Corsa sounded good, but the difference was not different enough from Stock at all RPM's to really give me what I was looking for. It also took away the multi mode exhaust function.

The Borla C6 Corvette Z06 Exhaust system installed pretty easy and sounded awesome at idle and driving around town. But damn, the highway was a different story. I had Borla stingers on my C5 Z06 and there was some drone, which I could live with.

Maybe I have just lost my tolerance too it, but the drone on the C6 Z06 with Borla's was unbearable (for me and just about any other passenger I took for a ride). I had to get them off the car.....Take a look on any forum at the C6 Z06 parts for sale...You will see C6 Z06 Borla's used for sale on every forum. I think I am not the only one that had this issue. Also, like the Corsa, no more multi mode exhaust.

I had never heard the BB Corvette C6 Z06 Fusion System nor had I had any experience with Billy Boat Systems. I figured I would give it a try, but really did not think it was going to be what I wanted, but I did like the idea of keeping my multi mode exhaust. Upon opening the box, I was very impressed with the quality of the parts. Installation was a breeze, with very logical engineering. Everything was easy to access and tighten down. The sound at idle is a bit more aggressive than stock. Acceleration was a different story, when you pass the magic RPM point for the Multi Mode to kick in, Oh my god.....the perfect sound. Just what I was looking for. Toss in a Mild to Wild switch, so that I can control the Multi Mode and finally, exhaust Nirvana.

The cool thing (unlike the others) is that you can control the exhaust sound just like the OEM system. So if you are cruising down the highway, you can shut the baffles in the exhaust and enjoy quiet near drone free driving. Open the baffles, and bam, the thrill of driving a muscle car is back in your face (and ears). Not an obnoxious sound, but a throaty muscle car sound.

Anyway, trust me....If you have a C6 Z06 and are considering an after market exhaust the B&B Fusion Corvette Z06 system is worth a look. I know this sounds like a sales pitch, but I sell all of the above mentioned systems. I just am that excited about the fusion system that I thought I would share my thoughts with the blog.

Pictures below are some shots of the B&B Fusion system on my car...
