Headers
I would like to thank every body that helped me save money and not waste it on buying a brand name cool air intake now I would like to ask if any one know the effectiveness of headers the best ones and their price

keyword guys is HEADER
anyway use search and if that dont help then go with a dc pretty inexpensive and nice, if u want low end to mid power get 4-2-1
if u want mid to top end power get 4-1
pretty sure its like 10-12hp gain

I don't understand why u guys claim that a 4-2-1 has better low end and mid than a 4-1 header. What's the logic? I know I was never good in physics...but help me understand plz. Isn't all header created equal if they're the same in design? Just 2.5" tubing.
been there done that

Like I've said in almost every single thread you've made about bolt-ons...don't bother with them if you've got an auto transmission.:a:

Here's what came out of the article on the 4-2-1 vs 4-1:
CONCLUSION ABOUT HEADER DESIGN
So the old adage that 4-1 = more peak hp with a loss in midrange torque and 4-2-1 = more midrange torque with less peak hp is an obsolete idea.
Newer hybrid headers of the 21st century are a fusion of the old 4-1's extra length with the 4-2-1 layout, have stepped diameters, and have large diameter collectors. So you have low end peak torque with enough breathing capacity to support more peak gains (the best of both worlds).
