TR6 Header or Duel Stock Manifold?

["Steve Nabors" <topdown@eudoramail.com>]

I've got a stock duel manifold with custom duel exhaust and was thinkin about 
using a Monza/Pacer 6 into 1 into 2 header.  Is the performance gain worth the 
money(ie can you feel a difference)? Is the Monza header going to fall apart in 
a few years?

Thanks,
