at risk of demonstrating my ignorance, When someone says they have "headers" on their 996, be they fabspeed, remus or whatever, what does this mean? i'm familiar with headers on a front engine muscle car, but they usually have quite a bit of exhaust running back to the rear of the car. what about on a rear engine porsche? do they run into the factory exhaust, or does this go away?

 

I always considered headers means there are the whatever # of tubes coming from the engine going into another 'collector' tube... as opposed to like a manifold being a larger cast piece.

 

Headers -

 

OK. so more open flow into the muffler assembly and apparently less weight versus the factory exhaust manifold casting?

 

Yes and Yes

That combined with high-flow catalytic converters and a free=flow exhaust and you have one very nice sounding setup. There is HP but after I spent $3K for everything I had a tad bit of buyer remorse just because my expectations were pretty high. Some gain but nothing other-wordly. Would I do it again, probably

 

agree with^^^

Power gain is very minimum... but sounds great. I have a B&B headers, stock cats, and Fabspeed exhaust. Love the sound.

Would I do it again....yup.

 

The general consensus seems to be a gain of HP at higher RPM's, but a loss of torque at lower /RPM's.
