hi, after some opinions on after market headers for an 02 wrx. thought i had read somewhere that the original cast ones were better.

 

avoid the cheap eBay ones. Race dynamix website have proven they loose power. Get the originals ported

 

Cheap stainless ones will fall apart very quickly. Even some of the more expensive stainless ones are just the cheap ones renamed and with a few £100 added to the price! The killer B ones are the only ones I would go for as an upgrade and they are crazy money.

The OE ones last forever and can be ported to improve performance.

 

They may be expensive, but god they are worth it....
