This is really for Bob Brassell, but anyone else with experience can chime in...

I am about to buy a couple of new ST's, either 45's (ABC) or G51's (ringed). Does one of these respond better than the other to the Jett Stream tuned mufflers? What can I expect for RPM with APC 9x7, 10x6, etc props?


Thanks,
Mark

With those props, you will see a gain of about 1000-1200 rpm over the stock muffler. Probably a bit more.

Does one respond better than the other to the tuned muffler? I was reading your comments about the OS55 and it made me wonder if one or the other is better as a speed engine choice? I have a 45 now that is going on my Dominator 500 and one of the others is going on a Trouble Maker pattern ship, so it needs to rev up as well. What do you think, Bob?

Thanks for the help,
Mark
