Can some tell me if i will see any gain in Hp or torque? If so, how much? Is it worth the $$$ and trouble swapping them?

The 1 3/4 long tubes are Hooker Hedman's, The 1 5/8 shortys are MAC...

Thanks

The 1 3/4 might hurt lower rpm performance with your current setup because of the larger cross section. Still may help over 5k though. If you're planning on stepping up to bigger heads or a blower or something in the future, I say go ahead and get them, you'll want them later. If you choose not to get them, have your buddy email me, I might be interested...
