Hi all,
A few questions for all my fellow GT350 owners regarding the active exhuast:
When you do a cold start in the morning, does it sound like the valves are almost pushed open sporadically for the first few seconds as the engine is warming up? Mine always lets out a super loud scream at first, then it almost seems as if the valves close back up and it returns to normal.
Secondly, under moderate throttle in "Normal" mode, the valves seem to open up around 4-5k rpm and it becomes "Sport" loud even though i am leaving it in normal mode.
More or less it just seems that with enough exhaust flow the valves almost cant stay closed and it gets loud at certain points, whether it be during a cold start or on the road when i give it some throttle.
I dont necessarily mind it, although it would be nice for my neighbors if the startup was a bit quieter. Just trying to understand if this is normal or something that i should have addressed?
Thanks!
Mike
