Just a quick question really,are all the classic shape impreza headers the same im assuming they are as they are the same engine but id like to be sure

cheers

 

Original ones? Yes. Aftermarket? Definitely not.

Are WRX and STi, and UK headers all the same though?

I agree each aftermarket manufacturere of headers has their own ideas / design ... for better and for worse...

 

on the classic yes, they are all the same design, the only ones that differ are jdm wrx up to 96 as they had the lambda in the headers instead of the downpipe.

only differance being a hole for the lambda.

not sure about the 01-04 cars

 

Are you following me Jonny?! ...

 

lol

 

Or am I stalking you .... hehe !

 

yep agree.. my MY96 has oe ported headers that came off P20SPD MY99 and I believe he fitted my MY96 headers to his MY99 as a stop gap.

 

I disagree I bought a used set for a classic from Grade A to port for my MY98 and after doing all the work they wouldn't fit... The driver's side was the same (if I remember correctly) but the other was different so the joining pipe wouldn't line up. I sent them back and got a refund but I don't know which model they came from although I specified what I wanted. Just be careful...

 

that is very strange, all exhaust ports are in the same place on all heads.

you can fit a set of aftermarket headers that are made for an my04 on to a my93.

was it the length of the joining pipe that was wrong???
