Which Exhaust ?????
On a JDM Impreza S.T.i 2004. ( twin scroll )
What exhaust do you think sounds the best ?
NOT necessarily the LOUDEST !!! but a good grumble sound, well as best you can with the twin scroll and has anyone changed the headers ??
Need some feed back before i spend out on the wrong one..

Stu,
It depends on what you are after - when you ask if anyone has changed the headers do you mean back to unequal length? In doing this you loose a lot of torque - one of the best things about the JDM set-up.
As for best sounding you won't be surprised to hear me say Milltek. They are quality, well made kit that sound tip-top when opened up but not too loud as to pI*ss off the neighbours every morning etc.
They also give good power gains - my car was running just shy of 350bhp with just the system and a remap

In exactly the same boat , my 04 JDM STi still has the original exhaust on it & I'm looking to free up some power without going to loud ( at low speeds and motorway cruising I mean)
Was thinking about getting a Prodrive down pipe with a sports cat , with a decatted prodrive centre section & an STi Genome back box. Keeping my eyes peeled for any that come up for sale on here.
P.S Pippyrips how loud is the Milltek on a motorway run ?

Not that bad .. just turn the radio up !!
As Pippyrips has said .. off boost or just keeping the car at the same speed there is a deep but not too loud rumble ... open it up on full boost above 5K and it roars.
4k rev sound levels are about 96/97db but full boost about 102/103db .. although mine was recorded at 105db after a long day on the track.
Mine's a 2.5 " version btw .. but I'd recommend getting the 3" as its about the same price and can unlock 20+ hp.
Additionally, when I last spoke with Iain Litchfield just after Christmas he was saying that Milltek were investigating producing a slightly quieter back box. So, it might be worth touching base with Iain to see where they are with that.

This is the same system as was fitted to the T25's. I need to shift it soon as it's taking up too much room! pm me if anyone is interested

i bought mine on ebay, seen 2 in about as many years!
i think i've seen 2 on here aswell.
so all in all, not many come up
maybe if you can speak jap and have very deep pockets you can buy one new over there

Thanks guys for the info , I've just found out that the Prodrive exhaust won't fit on a JDM Twin Scroll car , there are limited systems that fit aparantly, Haywood & Scott do one, Janspeed aswell (Roger Clark system I think) and Milltek. Not sure If ther's any more , must be I would have thought.
As for the Genome , Japanparts.com have them if your minted ! £400 roughly , I'm on the hunt for a 2nd hand one
