Does anyone have a dyno result or 1/4 result after adding headers. On some other topics there has been discussion that Headers on an L98 only add 3 hp, I just want to settle the debate.

When I added the SLP 1 5/8" Tri-Y headers to my car that was the biggest seat of the pants improvement I made. No dyno numbers except the butt dyno.

A good set of headers is going to add alot more than 3 hp to a L98, have you ever seen the inside of the stock manifolds?!

wow, 23 hp from a full exhaust is pretty impressive, especailly when its at the wheels. Dyno numbers prove everything...3 hp
