American Racing headers or QTP headers ..... in terms of horsepower and tq. which headers produce the most

**nhraformula** · 09-16-2007, 05:15 PM

all long tube headers make about the same rear wheel horsepower.

x2

Look for things such as stainless steal and how well the pipes merge...esp the y pipe merge..

**basballny2** · 09-16-2007, 05:25 PM

so which have the better y pipe

Go with AR headers! you will be very happy, great y-pipe, slid right in and no y-pipe banging

doesnt it matter on your engine?!?!?!/1 for example...if you have more than 380 cubes... 1 7/8 or 2 inch headers are better than the regular 1 3/8's

That is correct, not all long tube headers are going to make the same power, maybe close, but if you are picking a few ponies here and there, you can find a few in different header designs.

Tuned length primary pipes, primary pipe diameter, stepped primary pipe diameters, collector diameter, collector length, try-Y, etc etc....there are so many designs, and power will vary with each depending alot on the engine combination you are running as well.

x2 is true but bigger isnt always better, like on stock motor, but would be true on big cube motors, its getting that correct /perfect balanced that really maximizews
