Hi I've just bought a second hand hks downpipe for my wrx classic and I was just wondering if anyone has one? Are they any good? Its got 2 connections at the top that connect to the turbo. Thanks.

 

All there stuff is good quality, you wont have any issue's with it

 

Pretty much all of the downpipes I've been looking are one pipe that connects to the turbo but my hks on has 2, 1 beeing the main connection and the other a smaller pipe connection. Is there any benefits from this?

 

I no what type urs is but unsure of what it's called the other the other type is called a open mouth downpipe .. Obviously the openmouth is better as there is it's completely open so no resistance but tbh I don't think there will be much if any diffrence .. Uve lost the cat eitherway if I was u I would just fit it will do the job just fine

 

It was only 50 quid and its hks so knew a couldny go wrong! Going to put it on during the week if I've got time got a new set of stainless headers and up pipe to go on aswell so should be a decent power difference. Cheers for the reply!

 

De-cat Up-pipe made a massive difference to my wrx but I don't think the classic has a cat there?
