7.5 K&B Exhaust

Postby Gaige2 » Sat Jul 28, 2012 7:21 am

Hello, I just discovered I have 2 brand new 7.5cc OB's (model # 8701) that I'm now going to use on a Prather 11 Lapcat.
Will adding K&B's new style muffler (adapter#30-8722/ muffler#30-8721/ gasket#29-8732) give this old model motor more power? Is it worth going to this upgrade or would I be better to go to your Muffled Marine Tuned Pipe #1349? If I go with your tuned pipe what Mac Header Part # do I need for this Motor and Boat combination as I'm not sure.
Thank you for your time and information.

The tuned pipe is for an inboard.

The canister muffler does work well and you will notice the increase in power.
