Hey, i just bought and installed a efini Y-pipe today. The thing is that i dont' see much of a difference in the OEM part and the efini Y-pipe. What should i expect with this upgrade?

 

increased reliability

 

Don't expect to get an increase in power because you won't.

I will buy it from you if you don't want it anymore..

 

It is claimed to be good for 10 HP. I doubt it does anything for relaibility though, unless your talking about the aluminium crossover pipe that comes with it.

 

Tobal, Was it easy to install? do youn have to remove alot of stuff to get it in there?

 

Actually the rubber coupler that connects the OEM metal y pipe to the plastic crossover tube is a known problem. It tends to tear and/or pop off.

I think it's a good mod, supposedly has better flow due to relocating the BOV connector out of the air flow. MazdaComp claims 10-15 HP, I guess that could be accurate. But I like it for the reliability factor, and the fact that it can be polished.

 

Well i hope i installed it correctly... seemed like a easy job at first and then i had to remove all these parts connected... i think its kind of a bitch to do. But after this you kinda have a idea of how your car is. But heres one big question that pops up in the install.. the inlet facing towards firewall with connects to the pipe w/ the actuator just plugs straight in right? Cuz it didnt' really stay all that tight but i guess after screwing everything it it stays in place. thats the only part i hesitate about. Please let me know this is how it suppose to be.

 

The y-pipe should fit in tightly.
Did you install a new oring?
It's part number N3A1-13-162.
This o-ring seals the y-pipe to the second turbo/actuator pipe.
