Is everyone really getting 18whp from a stillen exhaust alone? I've seen some independent dyno numbers, but would be weary of any advertised HP claim.

Not familiar with the Nismo exhaust design, but most true-dual exhausts will yield similar numbers. After accounting for dyno variance, real world performance will be similar.

Even if looking strictly at whp gains, I'd rather have a lighter exhaust that looks/sounds good over an exhaust they may yield a little more power.

I'm surprised exhaust weights are not being mentioned either.
