Looking to get a decat 3" downpipe on my 04 uk sti. It currently has an hks silent hi power on it, was on it when i purchased the car and love it. Just wondering which downpipe will fit, am i right in guessing the hks is a downpipe/back system?

Was going to get an hks downpipe to match but having trouble finding anyone who stocks these

Only reason i asked, seems some downpipes are longer than others (eliminating more cats i guess)?

Thanks

Thanks for the help. I think the HKS system elminates the second cat, the Milltek downpipe above looks like it eliminates the second cat to so i think i need a shorter one...but Im still new to this and not 100% certain. I thought a few people on here might have the same system. Heres hoping lol

Thanks for the help folks!

If you need the std decat pipe then it is the one below,which normally mates to your 2nd cat.

However you can also buy a decat pipe to replace the 2nd cat as below:

,which then joins on to your centre section.
