Cobra Exhausts UK
Hi, i'm looking for a full exhaust system for my Subaru Impreza Turbo 2000 (Classic) and i am interested in the trackday friendly system. Looking at the SC05 and SC25, a full decat system from the turbo back, the DB levels as mentioned on the site read in at under 97 DB, if i was to also get the SC27, the headers and up pipe, would this increase the DB levels more?
Is the trackday friendly exhaust just resonated to reduce sound? I'm curious to know if the same exhaust system as the trackday system was untouched to lower sound, would the exhaust flow/performance be different compared?
I've tried emailing you but no luck on a reply so thought i would try here.
Thanks

FWIW, my classic runs a 3"DP into a custom Cobra double resonated centre section (the same as their track day system middle section but in 3-2.5"), then exiting through the H&S ScoobySport backbox, and it still only manages 102db ish 
before the centre pipe it was making 104.8db at Snetterton I should have bought the Revolution
