Default what is an up-pipe?

I know what an up-pipe is, I just want to know what it does and I hear that it ruins your wrx. Is this true? Are they worth getting? If they ruin your car then why would someone get one? Thanks.

The OEM uppipe is a metal-substrate catted pipe that is part of the pressurized exhaust stream before your turbocharger. Essentially it connects your exhaust manifold to your turbo.

The replacement of this uppipe with a non-catted uppipe yields significant horsepower gains due to a significant increase in the flow of exhaust gases.

The OEM catted uppipe was designed to provide that extra emissions friendliness during start-up conditions, as metal substrate lights off earlier. The downside to this is that there have been many cases of the factory cat breaking apart and destroying turbochargers (aside from reducing exhaust flow).

In short I see very little downside (aside from maybe failing visual SMOG) of replacing your OEM uppipe with an uncatted version.

We offer the Helix flex uppipe as a solution.

Cheers,

Gary

It decreases spool time and offers more HP. And no it doesn't ruin you car.

Check out this diagram...you need one, dude.

Great mod to change it out with a catless version, but don't take it out altogether

maybe he was worried about voiding his warranty. I mean, why would something like that void your warranty if it won't break the car, right?

Anyway, yea....

wow. This level of retardation boggles my mind.
Nevermind the fact that what you just said isnt even possible,


Even on the almost certain chance that this was a joke post, its about the worst attempt I have seen at teh funny.

Funny not found. move along, nothing to see here

wow gurus take your panties out of a twist. it was completely sarcastic... read in context it has a point. an uppipe is a flaw, a weak point, a consequence of ill concieved turbo placement. i was pointing out the fact - sarcastically (yes, admittedly not funny - but everyone has their not funny moments) - that the evo has a better design. "an uppipe helps with turbo spool and will give you power". no, it doesnt.

dave grow up buddy. go take some uphill 5th gear logs of that magical vf22 youve got and brag about how fast it spools.

If it doesnt add HP and decrease spool time than what does it do, smart ass?? This is a Subaru forum, not a EVO forum.

Oh and by the way youll be suprised how fast the vf22 spools with supporting mods...

an uppipe in and of itself does not decrease spool time or offer more horsepower. as a somewhat knowledgeable person, i realize you were referring to the *removal* of the uppipe catalyst, but you were unclear. we're dealing with someone who doesnt know what an uppipe is, what it does, or whether or not his wrx came with one... you have to be explicit. you gave him an incomplete, out of context answer to a question he didn't know he was asking. thats all i was reacting to.
