I was wondering if anyone had tried the quiet core in the ProCircuit T-4 exhaust, I heard 92dbls but was wondering if anyone had heard or knows different, I also saw an ad for the new FMF powercore IV 2-'Q' suposedly very quiet.

It's good to that the makers of these after market add-ons have finally listened to the needs of off-roaders and duel sporters..

ben i've got the standard T-4, what a racket! if you want it it's for sale & you can modify it.



If your system is still for sale, I'm interested...I'll email you my phone number
