I’ve recently purchased a 2007 wrx hawkeye. 
 

the middle and rear is rotten and needs replacing. 
 

im trying to find a new exhaust but I’m stuggling to find which one fits. 
 

im finding new age, ect but I’m stuggling to confirm what is correct. i know I may need to change the down pipe too as a 3” won’t fit the original centre? 
 

Are new age, GD? The same. Are WRX and sti the same? 
 

Please help so I can get something ordered! 
 

I’m after something like this sub £500

Tbh i think your gonna struggle to find a decent full system for under £500. Avoid ones that have flexi couplings in them. Cat back should be achieveable though.

WRX has a cat in the downpipe.

You can get direct fitment cat back systems,

Bear in mind you may well need to have it mapped to cope with the decat, although if you keep the downpipe cat you may get away with it, would need to go on a  RR to check AFR's to be sure.
