Spec c downpipe advice
Can anyone tell me if the 3" downpipes available for a normal sti will fit my 2004 spec c or do you need a different one for the twin scroll turbo. Also where is the best place to get one. Cheers

You need a different downpipe for twinscrolls.
As for what's the best place - it's probably more a case of what's the best downpipe isn't it? I, and many others, rate the Milltek system but it's not the cheapest.
Powerstation are a good bet, but others will be along with their suggestions soon I'm sure!

Hayward and scott make a very nice system which fits perfectly. Be warned a JDM twin scroll 3" complete system will make your ears bleed... am not kidding here!!
Make sure you order one with a center silencer. If fitting it yourself make sure you put a flat in the silenced part if not it will knock on the prop shaft support bracket.
Here is a pic off a twin scroll DP.

When opened up, the sound is wondrous - a glorious howl, more high powered bike than car, due to the equal length headers on the JDMs.

Its different from the turbo to the back box mate. The downpipe mouth is a different shape and the center is the same as a classic impreza.

My Milltek seems to have a resonator in my downpipe and centre section. My brother has the twin scroll RCM exhaust, it's much louder than mine, much!!

Don't agree - the Milltek 3" decat only has a resonator in the centre pipe and it does NOT make your ears bleed. It measures 96dB at 6000rpm and 98dB at 4000rpm. My main complaint is that in the 3000-4000 rpm the noise is more than I'd like in a family car, but no one ever complains. A bung is available.
When opened up, the sound is wondrous - a glorious howl, more high powered bike than car, due to the equal length headers on the JDMs.

My H&S system came without it (full 3" free flow no silencers) and promptly got exchaged for a center with a silencer. Drive one without it, you cant hear a passenger when crusing at 60 never mind the noise it makes when around town.

Maybe i wasnt clear enough in my post above when i said make sure you order one with a center silencer.

I have a full system for sale designed to fit a Spec-C. It has a silenced centre section and a wrapped downpipe like the one pictured above. Here's the link https://www.scoobynet.com/private-sa...in-scroll.html
