I I got my Bosal header installed today, I love it! It does increase the torque and makes the exhaust sound louder.

Good to hear something positive about headers for once! Especially from a fellow NA with AT. :) I might just have to look into getting headers now.

i defenetly love the way my car drives and sounds after i put in my hp racing headers lots of tourque and nice deep sound i dunno y your all so negative about headers apart from the facyt that they make ur engine bay look really good

I'm happy you like the header Ken.

Yeah I am really happy with my header aswell. I could tell a difference when it was installed. The car felt and sounded stronger.

Hey ken, that header is the 4-2-1 correct? i was wondering what the actuall difference would be. I too like my header, I would do it again.

I love my header. It added a nice tone to the car and quieted down the raspyness on my intake, but the intake is still loud. The header makes it pull from about 3k - 5500 rpm range faster. I bought it off of a member on this board used for 130. It's a bosal header (4-2-1). From what I understand the 4-2-1 keeps the power band a little lower than the 4-1 header which tends to shift the powerband higher. If you want streetability you should stick with the 4-2-1 and if you take it to the track a lot you would probabally be better off with the 4-1. Hope this helps.

hey, did any of you have trouble installing your bosal header? All I keep hearing is install problems with headers( except for the greddy one)

I had a shop installed for me because the rusted bolted are Fxxking hard to remove.
