Ready to race!
i have drone at 2k - 3k rpm...especially at highway cruising speed of 100~110km/hr with my full SPM street turboback.
had it on my car for 2 months and couldn't stand the annoying drone at highway speed so i went with APR RSC full turboback. even though the SPM exhaust note sounds better but can't beat the RSC technology for cruising speed noise level
