Billy Boat or Corsa sound better?
#21
i have owned a corsa and had a friend with billy boats with the same heads and cam. Corsa all the way it’s so unique and badass.

The difference is night and day. Billy Boats are RAW all the time. The Corsa Sports are nice at low rpms but loud at wot. The Corsas do give a little drone in 6th going uphill.

I have the B&B Fusion IIIs and find the sound in the cabin is reasonably quiet with the valves closed except for some modest drone in the 1200-1700 RPM range, HCI LS7 with ARH 2" headers, OR x-pipe, ~600 rwhp.

Like I said, everyone has different taste. What one likes another doesn't. When I talked with BBE they told me any variation in the heads cam ect will change the sound and or drone. To each his own. We all have bad *** Z's that sound awesome no matter what muffler is on it!

I have PRTs and man they sound awesome. They sound deeper than my modded mufflers and have a better tone imo. At wot they sound brutal, and are loud. But man they drone a lot. I have a very mild cam, stock manifolds with no cats. I’ve heard they were designed with headers so maybe that’s why mine drone. Other than the drone they sound perfect.

Is your car modded? Or stock? If your car is modded keep your stock exhaust with a mild to wild switch. If your car is stock go with the BBE Fusions Gen 3. My car is modded and i put the BBE Gen 3 Fusion Extremes on, now in between 1500 & 2000 rpm i have drone. I contacted BBE because they say NO DRONE, what they told me was its considered no drone if your car is stock not modded. So in hind sight i should have just kept my stock mufflers. Not to say the Fusions don't sound Great! because they do. (look great too) Just cant stand the drone. I had to change the way i drive to avoid it. I will include some links so you can hear mine. Just my opinion, take it with a grain of salt. Everyone's taste is different and with out hearing it and driving in it you will never know.
