Not fitted one, but my guess would be, no and no.

The most obvious difference would be weight loss  :002:

well it s hard to tell but i ve noticed some kind of difference in performance, not much but a little more power. i fitted only one can and closed the other on the left side, that give me easier access to the chain for maintenance. Sound brilliant too. The fitting was easy enough beside the right silencer refused to come off because of rot. enjoy

I fitted a 2 into 1 Delkevic system on my Zuma a few months back, I didn't get the bike re-tuned afterwards and the performance has been OK. A few people have said that it would be worth doing and others have said no, I'm of the train of thought 'if it's not broke, don't fix it' so I've left it be. Performance wise you'll maybe see marginal improvement, we're talking 0.xbhp increase. Just enjoy the nicer noises & appreciate the shiny bits.  :821:

so no major back fire?! i already enjoy the sound of my slip on, much better than the original pipes and there is a little improvement on torque somehow...i think  :007:

Mine does 'pop' a bit when I roll off of (full) throttle.  :001:

yeah that s what is backfiring  :008: technically it s not exactly that good, your bike is running lean. that s when it s needs a tuning. mine actually does too with a slip on only ! but only a little bit. Sadly it s harder to have an injection tuned than carbs
