How is your experience so far with the Valvetronic? Also pulled the trigger on those ones. Will be getting them on Friday. Did you also replaced the resonator with an X or H pipe? Any drone when valves are open?
No drone at all on the valvetronic, the j pipe mitigates drone whether valves are opened or closed?
I did not put the xpipe on after seeing
@Twurbo Noob post on the valvetronic thread, but after talking to him he seems very happy, so I'm contemplating doing an x pipe next.
The biggest difference I noticed between the axleback and the valvetronic was the interior noise, the valvetronic is just as loud without sound leaking to the interior/rear seats. The 2-3k rpm range had drone with the axleback. Once you get settled into a cruising speed it's fine, the axleback is best if the car is gonna be somewhat modded, it adds a more muscle tone to the vehicle and I got so many compliments on the exhaust.
Overall extremely happy with the valvetronic, basically it’s loud on throttle and muffled when it's idling or cruising around.
