Anyone running Perrin Catback with Vortech or Jackson SC?

[Drakelee117]

I found this on the forum
(dB) Stock Resonated Unresonated
Free Rev 88 98 105
3000 rpm 72 79 83
4000 rpm 80 83 89
5000 rpm 82 86 89
Idle 58 65 67
Dyno 98 105.5 108

Does anybody has any of these exhaust with a SC? Will the noise level reach 95 db limit with a supercharger at 3k-4k rpm range? (I believe that is the range for the noise test)

We've done serveral JRSC on cars with the Perrin.

It does get louder (~5-7db?) when you're WOT (dyno), but if you're just holding an RPM, it will not see more than a 2 db increase maximum.

Technically, the catch can is not legal, since it affects emissions. Realistically? You shouldn't ever get cited for it.

You won't need a drop-in air filter for a CARB legal SC, unless you use the Innovate.
