Just installed it and trying to slide that silicone coupler is tighter than a virgin on prom night (is there such a thing any more). Anyhow, just wondering if anyone else noticed the same thing?

 

Absolutely no rubbing. Try a little soapy water on the coupling.

 

mine fit fine. no rubbing. still using stock intercooler.

 

let me know if you feel any more power? some boast a h/p gain. i did several other things when i installed mine. just wondering.

 

I've heard people say there is a HP gain as well... But I too did the install at the same time as other mods...

 

If your turbos have been rebuilt the compressor housings might be slightly misaligned causing the Efini y-pipe to hit the water neck. This is actally really easy to solve. Bolt the pipes up and push the crossover pipe to where you want it. It should rotate with a good push pretty easily. I just went through this.

I recently installed the efini y-pipe. Installation was easy with no problems or rubbing. I have the stock intercooler (for now). The Blitz is coming.

I did feel a HP gain, and there was a boost gain. Mazda claimed a 10 hp gain with this. I think part of the gain was due to the crossover tube being held in place. With the old crossover tube, it would flex upward under boost. So some of your boost was being wasted to expand this tube. It can't flex with the efini pipe.

no rubbing for me

 

no rubbing but i bent a screwdriver tryin to get that bitch in. Fits fine now, lol

 

Thanks for the replies. I'll try the above and see if I can rotate it. There was enough clearance to slide the silicone coupler on the tube (with some sex lube "lol"). I also had to rotate the pipe to the Greddy SMIC.

Yes, I did feel a butt dyno difference. Not sure about horsepower but more responsive. I test drove it late last night and it was back up to scary fast from just plain fast.

 

I wish I had my Y pipe! Still waiting for Msports to ship. Backordered.

 

no rubbing at all in my case.
