Billy Boat or Borla?
If I can find access to a 4 post lift I'm going to put an exhaust on my car. Don't really want Corsa so I'm looking at options,i understand the drone issue has been fixed with the BB and Borla.

Re: Billy Boat or Borla?
I ran Borla on my 1991 ZR-1 back in the early 90s. Back then Borla was the only aftermarket HP exhaust available for Zs.
My understanding is that Borla exhaust diameter pinches as it enters resonators. Also, I recall seeing a post that solution to B&B resonating may have resulted in creating restriction to flow. Another option is OBX. These look almost identical to Corsa. However, OBX uses more conventional sound reduction strategy - namely perforated pipe with fiberglass insulation ins the chamber. Resulting sound is more mellow but deeper growl at full throttle. I have been running OBX since 2013 (I think...) and only complaint I have is the exhaust clamps supplied with the kit are junks. I installed my OBX using Torca clamps. |

Re: Billy Boat or Borla?
I'm running OBX as well...Really like the sound but it is does drone in 6th gear.....All though I'm not really in 6th that much...
And yes the fitment and the clamps suck.... I noticed that when I got my bill from my mechanic.... Sent from my LG-TP260 using ZR-1 Net Registry mobile app |

Fitment issue? Is that what the mechanic told you? It was no better nor worse compared to Corsa. |

What rpm are you sensing the drone? Can you describe it? Are you running resonators? |

Drone will be different from person to person. Everyone’s ears work differently what might be drone to some will not be to others..

Re: Billy Boat or Borla?
I've tried them all and I think Billy Boat is the exhaust system that our cars are meant to run.
