this is why TTi headers suck for power

My buddy dyno'd an engine using his TTi 1 7/8 w-2 A body headers - 646hp
With the hedmans - 678 and there's more left

Here's a link with the pulls using the Hedmans.

The tti's are a stinking 40" long... maybe they should make those for a SB motorhome with w-2's :thebirdm:

Insane.
