1. How many aftermarket exhausts actually add meaningful performance
2. How many people actually need / notice / use whatever performance they gain
vs
3. How many people, consciously or not, admittedly or not, just get it for bling and sound
Very few people with aftermarket parts take their bike or car on the track or competition. Very few have training to take advantage of it.
(I don't speak from a theoretical high horse - I spent thousands of dollars myself to add power to my WRX, before I finally realized that 1. Stock car was already faster than myself, and started investing in lessons/training/practice runs, and 2. The hands-down best investment I made in my car was a $200 aftermarket (additional) multi-point seat harness, as it stabilized my body/arms and enabled a much much finer degree of control. If I were to modify a car today, I'd start with suspension/control, not engine/power. For bikes, even more so - every bike I ever owned, from 50 scooter to 400cc supermoto to 500cc adventure and 750cc touring, can do amazing things in hands of a professional rider and can do far far less in my own hands; modifying it for "performance", for 98% of riders, is pointless and we're only fooling ourselves )
