How far to rev this 273 commando build

Tail pipes can make a big difference. BIG

I had installed tailpipes when I had the flomasters 40's on ...... It got so rappy............. I took the tailpipes back off.
I think the only thing that is going to quiet this beast up is a x or h pipe.[/QUOTE]


That will help as well. Tail pipes mellowed exhaust long before x and H pipes were popular though. Just sayin'
