So after trying to see how high I can rev the Honda Accord 1.5T Sport CVT 10 Speed Automatic transmission, it would not go past 4000 rpms. Is there a way to do so? Would it be a tune? Also which exhaust would sound loud without going with a downpipe?
Can't answer your question as I've never sat at idle revving my engine... even if I did I probably wouldn't rev it that high. Have to ask why one would want to rev their engine that high at idle in park?
