So, I was driving the other day in my wife's 91 honda accord and noticed that in 5th gear on the highway doing around 65-75 mph the RPM's were around 3k or higher. This doesn't sound normal... I mean, I know the car has 244k miles on it, and the muffler fell off awhile back (too lazy to fix just yet) but I didn't think a muffler would seriously make that big of a difference... that's the only thing wrong with the car that I can think of. Anyone have any ideas?
Also, it's not just in 5th that the RPM's are high... it seems like almost every gear has high RPMs, but the idle is nice at like 700.

My DD 4 banger is way higher compared to my SS on the hwy. The reality is that's how they are geared bc they have no torque. That's how high they have to spin in order to maintain speed and slowly accelerate without downshifting in OD.
Yeah, I had been googling the issue a while back and could never remember seeing anything that would make a difference. But I found a Honda forum today that told me exactly what you guys just said.
Would putting a muffler back on the car cause any difference? Lower RPM's or better gas mileage you think? I know it'll quiet the stupid thing down, but I plan on selling it soon so it wasn't really an issue. But now it looks like we'll have to keep it longer since me buying the GTO fell through.
no it wouldn't make a difference. all hondas run high rpms compared to even some domestic 4bangers, but thats the way they are. my friends b16 is at over 4k rpm at 70mph. its just the gearing they have. even then they kill on gas mileage. nothing to worry about.
