    Currently the PNW tracks (Ridge, ORP (middle of nowhere), Pacific Raceways) we are lucky to not have sound limitations. I have to say PNW is awesome for a track junkie,, rain or shine
    I think only Portland has some sound limits though.

    If i every drive from Seattle to CA for some track days with you guys(which i will surely do at some point) you are right, i will for sure need to double silencer + rear config for sure.

    I know the standard Caterham single silencer with side exit is too loud for Lime Rock circuit as that limits at 96db, however, I suspect my issue there may also be intake noise... You will have the same problem as me if a 96db limit is applied. A 420R can just sneak past a 96db sound limit at Lime Rock using a single silencer and side exit.

    Wish you were on the east coast, I know a bunch of Caterham track rats (Simon, Seb, Jeff, me) who would love to play tag with a 620R!

    Yes, would have loved to hang out with you guys in the east coast. I did miss dunkin donuts too (Seattle is Starbucks country)

    I actually used to live in Boston for ~10 years before i moved here, in which i daily drove a Lotus Elise with 60k miles on it Rain, shine or snow.
    You'd be surprised how easy it is to power slide a Elise on fresh snow with proper tires! I was young and stupid then... now, i'm not that young anymore

    Cem,

    Do you want the carbon fiber "canards" installed? They go on the nose.

    Yes, that sounds good. Also not sure if you saw the earlier msg on the side loud exhaust setup vs rear exhaust😁
