if u want a race header, its 4-2-1/tri y. for 4-1 u need shorty, and then hiflow cat or test pipe. race headers are your best bet if u want power, get one with a cat delete too. guessing you have an si?

redundant sentence is reduntant. race header= no cat; that's why it's called a race header, as opposed to a street header, which does have a cat and is street-legal.

in most of your posts you're very blunt and concise.

vibrant race header comes with either a hfc or none. i love my vibrant with no cat, sounds awesome, and a big difference. my friend has the catted version, cant even tell he changed the header

Yea as usual Vladd...you're wrong. Go to the Vibrant website. Their race header comes with or without a cat.

aww you're hurting my feelings. if it makes you feel better, the header with the cat is also listed as off-road use only on corsport's site, which explains the 'race' designation on it.

Anyone can call a header a "race" header.

A 4-2-1 is going to offer better power below 5000 rpms and 4-1 will offer most of it's power above 5000 rpms

Google "4-2-1 vs 4-1" and see what you get.

A lot of people like a 4-2-1 header because it offers more power down low, where Honda's are usually lacking. A 4-2-1 header can make a car more fun to drive stop light to stop light but for all out performance the 4-1 will offer the most power. Except 0-60, I don't know about you but I don't race my 8k rpm Honda below 5000 RPMs
