name that catback
Can anyone identify this catback? Besides some drone it seems pretty good, but I am running close to the sound limits at some events. Wonder if these mufflers degrade, I haven't changed anything. Are these mufflers heavy?
(haven't had it off - yet) Thanks, - Jeff |

It's Borla, I have it on my Z. You may lose 5-10hp on this exhaust setup, but it has zero or minimal resonance. With a set of Headers, No Cats, modified resonator the system works great. It's quiet but comes to life when you get on it. If you are looking for something loud, go with another exhaust like B&B. |

You modify existing resonator or you buy LT-4 resonator. |

Re: name that catback
I see.. I have the Borla Challenge system.. I have a LT4 resonator and I also have a Magnaflow resonator.. debating on which to try first

The packing can get compressed to where it does not work as well, or get shifted around or blown out of the casing over time. So yes, they can degrade. If you've had them a long time and they seem louder now than they did, it's possible that's what happened. Heavy, I don't know. I don't think the weight range is enough to choose a muffler based on it vs sound quality. |
