No muffler drone??
Setting up a car for 80% track day, and 20% street.
If I delete the mufflers , will it drone? I hate drone ... even on the track. |
You'll be deaf so drone won't matter much.

On what occasion would a car drone on a race track? Drone is a booming noise that happens at constant cruising speed or during moderate/low acceleration. Like tipping throttle in for an incline or something. |
I ran mine at nats each year with PLM header, berk cat, stock resonators and no mufflers at all (Turn down/dump right where the Y in the pipe starts). No drone really. Louder than normal. Not in any way super loud. Under WOT at around 7000 rpm or so I think it blew a 94 dB at 50 feet. If you do not have any resonators in the chain then it would be louder. But I would not expect a tone of drone as you are thinking, just more sound out the rear.

I mean its likely going to drone on the street. Not sure why you'd do this really. Weight savings? You not really going to gain significant power from removing the mufflers. Swapping the cat to a test pipe would provide more of a power gain (add a tune on top of that for best gains). I guess you could just remove the OEM catback for track days and put it back for street driving. Seems like a hassle though.

Drone usually happens at certain RPM's ranges, and happens during acceleration. Ask me how I know.
Yes. My question still remains... |
