top speed header

hey, guys.
my friend just put on the header for me on today.
but i find something interesting.
the diameter of stock pipe is bigger than top speed pipe.
im wondering how come it increase power if its smaller?

cuz the design i guess 4-1 deliver power at high rpm 4-2-1 deliver power at low n mid range rpm

was it easy to install?

gets more power because of tuned length runners...

doesnt get as much top end power as TODA because of the smaller pipe...

Looking at the top speed primaries, I am still not convinced that it is a tuned length header.... One of the pipes is EXTRA long. If it was tuned length, it is tuned length for a particular RPM only.

ive never seen top speed headers lol i was just guessing as to the design based on most after market headers...

lol one runner extra long lol

lol one runner extra long lol

<--- for extra poW@ ROFLMAO!!

but in the end, its got a smoother runner curvature (how do you spell it rofl) rather than hard angled ones like the stock.

basically yes you guys are right.

Ive had mine in for a year. Its an exact replica of a DC sport header but stainless steel and welded together really good. It has the crappy flex pipe but mines holding up.

The exit pipe diameter is smaller than stock by but it has 2 pipes not one big one. But ultimately I agree that it probably only lets the same amount of air out the stock header. That being said its much smoother and much less restrictive than the POS stock header.

So I think that swhy my dynos showing more mid range, that and my jtune 5000rpm vtec. Makes the car easier to drive,but doesnt have ultimate max powa due to my tight arseness not ponying up for the toda.
