guys, will this work w/an hks uppipe without any modifications

 

downpipe have nothing to do with uppipe..
they dont connect together..
they just connect to the turbo..
any downpipe works with any uppipe.

u just need a catted uppipe to filter out some stink and fix that fat leak you have..

 

you should go for a twin scroll conversion.. with vf37.. hehe.. i wish i can have that..

 

Make sure the Helix Dp will mate with the stock cat-back or after market exhaust if you have one.

 

I think all cat-backs, stock or aftermarket, mates up perfect with the helix dp, expect for jdm exhausts.

 

is your cat back exhaust a flat or donut sleeve? flat will have a tiny leak on the top. you will need a second gasket to seal it up. that's what i did with my JIC. donut sleeve will mate with no problems. the downpipe doesn't connect to the uppipe, it connects to your turbine. you will need to shave your heat shield a bit b/c it's a huge 4" bellmouth.
ps. call me foo about the helix!

 

hks up pipe? damn.. you need to pull the motor out and turn it 5 degrees and re install into your car.






























hahaha jk it should be ok listen to eds suggestion

 

didnt you already buy this???

 

dont you remember? this is francis, he buys first then asks questions

 

got it installed today, made my exhaust a little louder
it's weird because no cat means it should be louder but its the opposite with the helix

 

Did you get the leak fixed too????

 

it's louder because of the 4" bellmouth design and wastegate flutter is very pronounced with the td04
you can try the wastegate arm fix...

 

Speaking of conversions any"juan" see pics of the Blitz twin turbo kit for the impreza? I saw it at TAS, just wondering if any pics made it to the interweb

 

seen it in magazines...looks amazing...miles of plumbing!! lots of bling...

 

blitz twin turbo impreza?... no problem.. here you go
