im just curious what kind of downpipe is popular among the sti owners:banana:

 

I'm using the Invidia downpipe, but it throws a cel. Other than that I love the downpipe.

 

P.D.E

 

p.d.e. dp here also which wasnt in the poll

 

isnt perrin pde?

 

no pde is performance design enterprises

 

ooooh stupid me

 

does anyone recccomend a website that sells that?

 

go to www.boxer4racing.com thats where i got mine

 

cool thanks

btw is the only difference between the helix dp v1 and v2 just the cel fix?

 

ummm i dunno about the cel fix. i thought the diffrence between the two versions was the bracket that they adjusted for a better fit. im not 100% sure though.

 

I am thinking of running a short DP like the new Stromung 3" Down Pipe with a wastegate tube anyone runing this on a STi?


areg

 

i've sold quite a few dp's to STi owners... mostly Invidia. CEL's are normal and do not cause any power loss, but apparantly its still a concern to the new owners of factory turbocharged subaru's. if thats the case, get a resistor mod or buy the PDE ones... OR stay stock.

 

ill be going with a godspeed...

but until i get it i guess my opinion doesnt count

 

Just installed a helix and was very impressed with the quality for the price, though I dont know how much difference you can expect from one 3" belmouth DP to the next. this one fit perfect, was welded very nicely, and has a nice thick mounting flange, gruppe-s threw in the 04 cel fix and new gaskets for free to boot

check the pic for the only mount on the helix, I guess this is the version 2, I know some DPs designed for the WRX have a second mount higher up that has to be ground off to fit the STI, no prob here!
