Does anyone know if there is a difference in power between the solid header and the 2-piece? I'm sure there is a reason for cutting the header in half i just can't figure it out.

which is better 1-piece or 2?

 

a 2 piece in some cases are easyer to install due to a cars lack of space to fit ****... thats all i can think of

 

Personally, I believe for my application, the one-piece was easier to install. The less pieces the the better as far as I am concerned.

The other thing is that 2-piece are usually 4-2-1 and one piece are generally 4-1. Not always but, in those cases the 4-1 is usually better for top end and track use and the 4-2-1 are widely accepted as better for the street, but we are only talking 1 or 2 Hp in any rpm range.

 

but they give a decent amount of torque. now you can keep up with the soccer moms going up a hill!

 

2 peices are easier to install...but really not that much easier if you have someone helping you. if i was going NA id rather get a 1 peice simply because with less peices theres less to go wrong.

 

In my book, less parts means less things to lose/go wrong/break/install. And its just as easy to install a one piece as a two.

I think the reason they would come in two piece would be to make it easier to put together. Theres no difference in power, so I cannot think of anything besides trying to make it a little easier.

 

Thank you for the input....I bought the DC Sports ceramic coated 4-1 one piece, for 260.00 after shipping

 

prolly what id get if i was staying NA

 

Good choice, a lot of people here fly under the DC flag.

 

a knoledgable friend of mine told me that 4-2-1 and 4-1 depends on whether u want better top end or better mid end speed...i forgot which one is for which but a little google reseace will do the trick
