I need more TIME!

Question guys using bolt on(wrx style) turbos, what piping did you use?

ok I've got a wrx up & downpipe, And I plan on goin with a vf39 turbo. But I DONT want to swap out my crossmember(HUGE pain in the ass)

what have you guys used as far as piping goes??

subaruchad's up/down pipes dont mate up to any exhaust...And I have no way of getting one made around the boston area. (no mandrel benders that I know of)

what should I do??

any monroe style muffler place can make a custom pipe so you don't have to cut any structural part of the car! that will cost the same as a cross member($50-75). if you knew length, dia, and ends you need you may be able to find at auto parts store. i used rubber hose from diesel trucks. some pre curved, some str8 hose. dosen't collapse and stays cooler than metal will. cheap is what interested me first!

yes, unless you can find a small enough cat that will fit subachad's downpipe. It is 2.5", pretty sweet. Got a jet-hot coat for it too

Hmm... Well you have two choices:

A) Suck it up and do the crossmember
B) Dump the WRX uppipe/downpipe for something that doesnt require the xmember


Thats pretty much it.

I'd do the crossmember, its not as hard as you think.

well, if your not mechanically inclined, leave the xmember alone and buy the aftermarket piping.

if you are halfway decent, replace the crossmember. If you want to do it cheap, modify it.

Anyone have pics of a modified xmember? I dont think it destroys the structural integridy like White2.5rs suggests.

yeah
i wouldnt take my car around a turn at 100+ with an x member like that

<on a track of course>

you can do what you want lol but thats WAY too ghetto rigged for me

i attempted that like 2 years ago...got real scared and polished it out

i have a 1" hole in mine and it still kinda worries me but not too much since i know its polished and there are no weaker points around the circle

dont be a biotch. make the pipes to bend around the cross member. use a wrx downpipe (aftermarket) and modify it.
