I would think to a certain extent that smaller diameter, ahhhhhhh who knows!
I give up. I know what I want to think in my head, but I can NEVER put it down on "paper" the way I think.... Damnit this scares me!
Happens to me all the time Gerald, there are exceptions to everything.
What diameter headers and exhaust, have a lot to do with what other mods
you have, and where you want the power to fall on the power band.
The companies that manufacture, or sell headers for Vipers, can guide you the
best diameter to use on your car. Plus, you can't lump all stock Vipers in
one group, some years respond better to exhaust changes. We all have read
posts, where no power change was noted after exhaust mods. I can't recall
any posts where someone has lost 'power', although there torque/HP peaks may have shifted.
