This guy is a good seller I was interested in downpipe but had a issue with my motor

Well, here is another... http://www.ebay.co.uk/itm/HKS-Turbo-Down-Pipe-Subaru-impreza-GC-CF-chassis-EJ20-engine-/231280241975?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Model%3AImpreza&hash=item35d9606d37

 

60 bucks more... but still... :P

Bought it... lets see what happens... it says that used to be at 166 pounds, but they wanted to get rid of it... "Clarence"... lets see...

Think you'll have to extend the o2 sensor wires due to the boss being lower down .

also it won't spool as early as a bell mouth/snake head type due to the wastegate side being blanked off .

Here's a pic of my snake head decat downpipe with a divorced wastegate (flap between wastegate and turbo )

Thanks! Yeah, I cancel the purchase... the people from the eBay e-shop told me that it was designed specially for the Impreza 5 and 6... where did you bought your bullgdog? ;) looks quite nice to have the wastegate with a decent space... ;)

 

Wondering why the HKS one doesnt have it... 

[savage bulldogs]

I searched eBay for about 4 months till one popped up, emailed the seller and "bought it now" instead of bidding cos it had 36 watchers[emoji6]

Not sure why the hks isn't bell mouth mabey it helps the smaller turbos back pressure .

It would've obviously been less restrictive than the catted oe downpipe and they both have the same flat flange design.

I fitted a cobra sports cat which was bell mouth and could hear the spool difference .

Pic of oe vs cobra

I haven't been able to find any supporting info to say whether bell mouth or divorced wastegate performs better .

hence why I snapped up the cusco as it's snake head with a divorced wastegate (best of both worlds) and the only one I've seen .

Niceeeeeeeeeee congrats bulldog! :D Nice upgrade you have there... :P

[Martin959]

I have seen some time ago, that there were some down pipes with the wastegate and the normal turbo "out" separated by a pice of metal in order to "dont mix the gases to get rid of them even faster... also could produce some flames (?) xD

[Martin959]

It was not exactly this one the video, but apparently are called "divorced" down pipes... :P

[savage bulldogs]

I think most divorced downpipes have 2 pipes with 2 holes in a solid turbo outlet flange, instead of the flap with a open mouth turbo outlet flange .

I think divorced ones are supposed to stop the wastegate gasses causing turbulence to the hotside turbine .

But open mouth type with 1 pipe might help spool [emoji15]

So fook knows which is best cos can't find any back to back test results [emoji4]
