My dad gave me his quicke 500 with an old K&B racing engine on it. I want to put a tuned pipe on it, but know nothing about them as most of my planes are sport or 4cycle.

Can anyone out there help with what parts I need and where to get them and how to tune a pipe?

Thanks for your help.

have a look there, i dont think they any K&B stuff but no doubt they'll have what you want, theres also a tuned pipe section and they send you a guide with every pipe they sell..
the Weston UK Pipes are also very popular www.westonuk.co.uk

Is it the rear exhaust? I may have a header and nitro pipe for it. I used to race but don't any more. It is louder than heck but produces a ton of power. Let me know if you want me to see if I still have it.

look at this site!!!
