Hi,
I have aftermarket twins & downpipes, and am looking to replace my OEM catback with an exhaust that produces a turbo "spool down" sound when driving, similar to this video. The VRSF Race sounds like what I'm looking for, but I fear it's too loud. Would a resonator quiet it down enough so that normal driving is not obnoxious/police magnet BUT still maintain similar spooldown sound? I'm not necessarily set on VRSF - I'm open to anything that produces what I'm looking for. Thanks in advance |

its not obnoxious if you put a resonator on it but its NOT quiet any way you drive it. If you want it quiet while driving normally go for the street vrsf not the race, id still add a resonator even with the street exhaust.

Car is factory arrest-me-red colored, but looks bone stock to most trained and untrained eyes, so I can probably get away with more decibels than say a hulk green car with 4.5 inch tips and an aggressive body kit. Nothing inherently wrong with with the latter, it's just that police are literally looking for a reason to pull you over at that point. I'd love the race, as long as I can drive at 2 - 2.8k RPM without being a jerk. |

When cruising it's not loud. For me it's the perfect exhaust for the money |

I'm not sure if you've seen this video but it'll help you out if you decide to do it. You don't have to weld resonator, you can use 3.5 ID to 3.5 OD exhaust clamps |
