Expected exhaust roar in RPM ranges with aftermarket
What do you guys observe with your aftermarket exhausts?
I just installed FI and with closed valves I’m hearing: 1K rpm - very quiet 1500-2000 rpm - loud 3000 above rpm - soft I like the quietness with closed valves. That’s the whole purpose of valvetronic exhausts so you can quote them when you want. I’m trying to figure out why it’s loud around 1800 rpm with closed valves. |

Most likely just exhaust drone your experiencing from 1500-2000 pretty much every aftermarket exhaust is going to do this even with closed valves. I get it as well with just a muffler delete.
