Mornings to everyone. After replacing the stock pipes a couple of months ago with some GPR Furore Nero ones I have noticed that my fuel consumption has gone way up. With the stock pipes the bike would average around 5.5L/100km in-city, now with the GPR ones it's easily averaging at least 7.5L/100km in the city. That's about 25% increase in fuel consumption. Is this normal? I was under the impression that when installing aftermarket pipes the consumption should normally go down, not up
All I did was remove the stock end cans and install the new ones (so simply slip-ons + link pipes, not a full system). Db killers are installed, there are no catalytic converters (planning to install those as well), no power commanders or anything - the rest of the bike is pretty much stock.
Can it be that I did something wrong? It was the first time I replaced pipes myself, but I didn't really see much margin for error, it was a pretty straightforward process.
As a side note, I'm not interested in performance increase or anything, I'm quite happy with the bike as it is - I really just wanted a bit more vroom vroom (and the weight reduction doesn't hurt either)...
Would greatly appreciate any insight or advice as to whether there is anything I can do about this. Big thanks to everyone in advance for your time.
