Which portion of the airflow pipeline does this part belong?
Is it connecting the turbo outlet and exhaust system? I wonder if changing this a good move for my 2003 old car and will it easily cause boost leak (or little risk as it is just the front part of the exhaust system)?

thanks

Ooh
from the adv
it said it has gain less weight and less heat etc
thks

After googling header a sport one will decrease torque at the lower end and needs sport exhaust :

Regardless of the manifold, we recommend making the rest of your exhaust system less restrictive before you install headers. This means installing larger-diameter, mandrel bent exhaust pipes, and it definitely means using freer-flowing mufflers. There's no benefit to putting headers on if the exhaust flow is only going to be choked further down the line.

i see a sport one locally at a very attractive price . It is just for racing and i would prefer to have more torque at low rev
