Silicone Induction Pipes. Yay or Nay?

[boyracer693]

I've been reading a bit online about these Silicone induction pipes people get for their WRX's.

Its mainly mixed in terms of effectiveness. some say you get more air flow into the turbo but others say its exactly the same as factory and makes no difference

Do any of you know whether they are a good bang for your buck upgrade or just a visual upgrade?

Looking for a few small things i can do to make my V7 wagon alot more fun to drive

Good noise in my v7, recirc much more audible, threw my MAF scaling waaaaaay out as there was less restriction, easy fix with tune though.v7 ones are a bastard to fit, whole manifold has to come off.

I assume the manifold has to come off for all versions. I just bought one off eBay for $80, biggest reason for me is its hard to find factory ones where the pipe onto the turbo isn't sliced. That in itself is a benefit.

Maybe for ****ty ones... I've fitted a couple on V7s now and they went on without removing the manifold.

Easy enough to remove without taking manifold off; it's getting the old intakes out without taking the manifold off that can become troublesome..

General consensus: Silicone = good.

You just hack it to bits with some sidecutters and a hacksaw blade with a rag around one end. It's not the worst job in the world, although it is pretty ****e.

Boon; remind me to never let you near my plastics.

Angle grinders are way cleaner hahahaha.

But yeah, I don't like cutty cutty.

There's a video of this intake pipe collapsing on the web somewhere, so ensure you get a good quality one (Samco comes to mind). I'm having trouble tracking the video down, but will add the link once I find it.

Seriously though, you would rather remove the manifold (and replace the gaskets) than chop up a factory intake pipe that is probably already split and you are going to throw in the bin immediately anyway?

And if you can get an angle grinder into the spot that you need to be to cut off the BOV recirc fitting, without cutting through the manifold as well, then more power to you, but I'll stick to my ghetto (but very effective) tools.

Sealing manifold spacers; no gaskets needed

If I do have to replace the manifold of the STi; it's gonna get powdercoated, and awesome phenolic sealng spacers.

Legacy already has 8mm phenolic spacers. so I probably would remove the manifold.

Lol my experience with angle grinders.... Lol all for putting it in eithout removing manifold though less hastle
