Hi, I have a 99 RA wrx with standard tmic (the one without the elbow for blow off), Am I correct in thinking I can replace the standard black plastic Y pipe for the one thats on an sti- the ally pipes and rubber hose jobby?

If so, anyone got a spare one?

Any thoughts on this guys, thanks very much.

 

...or go for a silicone hose? any advise on best way to go?

cheers muchly.

 

Go for what ever you can get. I'd guess the silicon would flow a tiny bit better but I'd doubt there is much in it.
Whatever you do get, it will be miles better than the standard one.

 

Thanks for the reply dude. whats the word on the 'un-branded' silicone ones on ebay?
