I'm thinking about getting an up-pipe for my 04 WRX wagon. I already have a Helix highflow Dp and megan turboback exhaust setup.

I was just wondering what are the pros and cons of getting a up-pipe and if i should get a catted or noncatted. Are there any good brands out there?

 

Nothing but good from a NONcatted up-pipe. Just NEED some ENGINE MANAGEMENT. Pros... more hp(with a tune), quicker spool, no pieces of cat breaking off and flying into your turbo. Cons... need EM

 

i think what u really mean, is whether u should get a flex or non flex uppipe.

There are pros and cons to both flex and nonflex. Search and u will see

But for now, get an hks uppipe (it is nonflex). It's fairly inexpensive and fits well.

 

i just got a dc sports up cuz helix discontinued theres so well see how it fits

 

sounds good, so now that you mentioned the flex or nonflex, what are the differences?

 

Hope you have EMS with that setup.

 

No i don't have EMS yet, this mod is still in the planning stages, but for sure EMS once i get the up-pipe

 

Oh dude, get Engine Management as soon as possible. You are asking for problems running TBE w/o EM

 

agreed, that should have went in before or at the same time you put in the TBE
