STUPID QUESTION TIME!!!!!!!!
OK, So on your average automobile you have this thing called an exhaust manifold.
it a chunky, ugly, piece of casting....sometimes aluminium, sometimes iron.... that is all rough and messy inside and generally mucks up the exhaust airflow process. ( turbulence everywhere, not very pretty and well, it's a "manifold fer gosh sakes.....get rid of it!).
Ahhhh then, there's the 'Headers'.....Serpentine curves of seamless drawn steel, smooth to the touch both outside and all the more importantly; along the inside as well.
Elegant in their simplicity and when properly engineered, the individual 'runners' are of equal length; redefining efficient removal of exhaust gases. (Back pressure??? What back pressure! It's like getting a third bloody lung fer gosh sakes).
Headers are so much better at doing what they do that one can easily realize as much as a ten percent improvement in horse power.
(More power.....never a bad thing).
I get dumping the heavy factory 'can' for something lighter. Dropping 9 pounds from the dry weight is amazing, even if there was no other improvement in performance!!!.
But my bike looks to have header pipes already....all bikes do. No ugly piece of casting hanging off the exhaust ports on my bike!
So what's the advantage and real potential gain with swapping out the 'factory header pipes' with an after market piece ?????
stupid question right??????
I'll shut up now.
