right i have a 2004 wrx with vf34,sports cat downpipe,decat upipe and decat centre pipe, now im thinking of getting some headers but i dont really no much about them which is best to get and what benefits will i see also whats the difference between equal and unequal length headers.

 

un-equal you will keep the scooby burble
eual length loose the burble

dont buy cheep ones off ebay, only ones to buy would be the gt-spec headers. buy them from mocom racing, as flat 4 online are!!! sh*te

they will improve tourque mainly, but will free up a few more hourses, good if your iming to the 350 bhp mrk

 

thanks mate for the input, anyone any experience of porting and wrapped headers?

 

harvey is your man!

 

just emailed him for some prices

 

hi mate i had a set of boola headers from the usa fitted better than standerd and where heat coated on the inside best mod ive ever done try to find them you wont find better

 

Get the GT Spec headers. They are the best of the lot.

i ported and polished my headers before i bought the gt spec. you do notice a slight better/quicker spool up if you port them. and so easy to do.
