Z Tube installed review

just installed my Z tube and its awesome! I noticed better responsiveness and acceleration instantly. I didn't notice any huge sound improvements. Still waiting for my K&N drop in filter to come in the mail.

Motordyne has dynoed the Z-tube vs the G-tube and found no difference in power, it's all in your head.

If you want a throatier intake sound then go for it.

If you are expecting a 10HP gain...you will be disappointed. All the tube does is eliminate some sound reduction baffles

You'll only notice it when you start to get on it. If you're driving normally, there isn't any sound difference.

Where is the proof? Show me a link that says Motordyne dynoed the z-tube on a G35.
