another thing to consider lowering the gearing to make it feel peppier, will have a detrimental effect on top speed. You will reach rev and speed limiters sooner and your top speed will be lower. Now this is where an ecu reflash would help as with a reflash you can raise the rev limit in each gear by 500 rpm and eliminate the factory top speed limiter.

Plus that process is less than 1/2 the cost of a slip on with a lot more real world benefit.

Gearing lower IS peppier, not just 'feel'.. I know what you mean, but to someone who doesn't understand gearing and engines this could be another point of confusion.

And on top speed, like most matters 'depends' is the answer.

Taking the limiter out of the equation, most vehicles end up being drag limited as opposed to gear limited.

Meaning they basically run out of enough available power to overcome the wind at speed- and simply can't pull the gearing even if 'on paper' shows a mathematical speed calc.

In such a case, gearing lower can actually increase real world top speed capability but not by huge amounts. The faster you go, the power required increases dramatically. A very small increase in mph can require a relatively large increase in power comparatively.

When you hear people telling stories talking about driving really high speeds- most are either bs, speedo error, etc.

I've been in cars before that will go faster in 5th gear than 6th for example.
