To straight pipe or not to straight pipe

[Jparkes43 329]

Hello on my kawasaki 227-5 17 hp single cylinder i was thinking about putting a straight through pipe on it and people time and time again were mentioning burnt or warped exhaust valves and i have no idea how bad this is or how common it is so i just want to know if i should or shouldn't straight pipe the engine 

 

thank you

James, not something I've looked into...

Welcome to red square, come and say hello in the euro section!

Is this a pulling or racing tractor? If so then go for it. But if you plan on mowing and doing yard chores with it I think you'll find the straight pipe to loud and annoying. Do you have neighbors?

Thank you for the welcome I was planning to take it racing and not really for garden driving, I was going to make the pipe long so it wasn't too loud but I thought it would help power

Thank you for replying

With a straight through on a petrol engine you could lose a bit of power. Petrol's need some back pressure.

ok thank you all for the replies, I'm just thinking of putting a cutout in the manifold so it can be quite and then on demand or if i want more power i could use a cut out
