Been in racing a bit (cars) and have to agree with Marius on this.
The insides of a muffler might look the same between the two.
The higher price of genuine exhausts piping, as well as mufflers, lays in the research done to actually make that difference, not in sound, not in looks but in performance.
There were at least 4 tuning companies in the days that manufactured different exhaust manifolds for the little 1.6 Lancia Fulvia Coupe for different purposes.
Some made these for the hill climb races, some for circuit racing and others for a rally.
Companies such as TYGA make their money designing exhausts for two-stroke racing bikes, Sebring makes high quality and performance exhausts systems for four strokes.
I have yet to see any competitive racer use any of the cheap mufflers from any optical or noisy copy.
I guess these are not called copies for nothing, it's like a fake Rolex or pretty common in Asis ÷lins.
At the end of the day no one needs any reasoning for running whatever on THEIR bikes as if this is what pleases them, all is (should be) good.
I didnít think you would take me up on the offer. In other words, put your money where your mouth is. I can understand why you defend the higher priced genuine Akrapovic slip on, you bought one!!!
Do you really think there is any difference in performance gain between the higher priced name brand, than the cheap knockoff? There isnít!!
Because all either one is, is a canister with fiberglass insulation inside that surrounds a perforated metal tube.
And stay on track Brother. Iím not comparing different motorbikes, just the different priced slip on mufflers.
Spend the money, enjoy the delusions!
