SBP Expansion Pipe On A GP 460 Engine

[5-7HEAVEN]

Anyone try this? My friend Rick is using a stock Happy Time exhaust on his 460 engine. He said he works well, looks good but not good above 10,000rpm.

Methinks the SBP pipe should allow my engine to rev up to its 11,000 rpm limit or more.....so I ordered one.

Heck, it's MUCH cheaper than other exhausts, and should fit the bike frame better.

Hawaii Ed said he'd help me tune and install the pipe.

Can't wait for it to arrive!

The SBP arrived last night. It fits like a glove on my engine and bike.

At least 4 other guys have done this with success.

Dang - I was hoping someone would send us their GP 460 for 2-3 years of research.

Excellent power, looks good too.
