Straight pipe risks

Hello all,

Currently I run stainless downpipes and a pipewerx slip on.

Now my plan is to have a piece of stainless pipe fabricated to the same length as the can I use and simply clamp that on when I fancy some noisy fun.

My first thought was to just take the can off, and it might still be the way to go. I'm just curious about engine damage. So many people on youtube (not really the most trustworthy source) state.. in some form or another, that running no end can can damage the bike, burn out valves etc. I'm sure some of you will be far more knowledgable on this subject.

I know the straight pipe.. in whichever form it will take will reduce power over the pipewerx can, but that's no concern as this will be an occasional thing. Something to use late at night or early morning :) I go by louder the better.

My car currently has a Y peice of pipe with a butterfly valve, one leads to a stock exhaust system down one side, the other leads to straight 2.5" piping. Perfect for mass noise and then nice peaceful no noise for coppers or long trips.

This will be the same sort of thing but not as convenient.

But I digress, just wondered which would be better and kinder to the bike, and if either will damage my bike.

Look forward to learning! :D

I doubt your nosy pipe would do too much harm to your engine if you only played with it now and then.
However if you or your nosy pipes ever turn up near my front door early in the morning or late at night it will be YOU that suffers serious harm. I have a special bit of pipe that would be fitted to your exhaust sideways on.

I know many of you will scowl at this and shout at me for giving bikers a bad rep but I'm just looking for info really, i'm aware this makes me a yob.

Yep, and I don't like being woken up when I'm on early shift by other people's 'fun', so personally I hope it totals your engine. :rant

Running straight through makes it leaner so no end can leans it way out !

Alright for a 40sec youtube but not for any form of actual riding :smt018

Shove in bigger mains and you should be OK for a while, if your car is FI it will compensate for this otherwise your burning out valves on it too all for noise - carry a trumpet with you if you really want to make a din :smt005

MM!
