Just posting a follow-up after a day of driving. My car hasn't been driven much over the weekend since I've been working on a stereo install.
The TDX with 12" resonators and Berk HFCs combination is VERY LOUD! As a daily driver, my tach is always hovering around 2-3k when accelerating. At this range, the exhaust tone is very loud. It even vibrates my interior. With SRM, the exhaust tone gets pretty loud as well. When letting off the throttle or cruising/coasting, the exhaust tone is very quiet.
Therefore, I plan to switch out the 12" resonators with 18" hoping to cut down the exhaust loudness. I still like the smooth and deep exhaust note, but I'm not much of a loud exhaust guy.
No regrets... just to quiet it down. ;-)
