What if any, are the differences between the two parts. (internally and externally) ??

"This is the replacement Y-Pipe from the 99+ Spec RX-7's. This new Y-PIPE redirects the airflow coming from the turbos more efficiently along with replacing the stock rubber tubing that is known to crack and leak."

 

Actually the "efini" 'Y' Pipe was introduced w/ the 96model year cars afaik the 96-98 & 99+ 'Y"' pipes are the same. However in 99 (iirc) the "efini" brand name was dropped and RX-7s became MAZDA's again.

 

So they both will fit a 93-95 FD and have superior turbo air flow over the "stock/factory" 93-95 y-pipe. .. And no rubber coupler between the y-pipe and cross-over tube.

 

You, Sir are Correct!

And as a added bonus it can be POLISHED for Bling-Bling

 

I likey mucho mucho the Bling-Bling.

Mazdatrix sells them polished for 267.00? Take a photo of your engine when you install the y-pipe and post it on this thread. . Thanks

 

TTT:
I thought you were going Single?

But really Nice Polish job there

I only did the y - IC (Upper) part on mine

areXseven: Lots of sanding and a 6" Buffing wheel is how you get that High Polish, I started off w/ a carbide cutter in an air die grinder to remove all the mold seams and risers, then coarse sanding drums on my dremel and finally hand sanding with progressivly finer grits (220, 400, 600) and finsh w/Aluminum polish and a 6" cotton buffing wheel mounted on a bench grinder/buffer

 

I think TTT (the King of Bling) did the polish job

 

Ever think about polishing members FD parts in your spare time (Hint-Hint). What would you charge to polish my y-pipe? Just bought a 99 JSpec . PM me if you like. Thanks.

 

Gotham Racing does polishing and they are right there in TX:

twinturboteddy used to do polishing - had a regular sweat shop going
pm him - But like Mahjik says - Gotham Racing does it an are in texas - or just look in the Yellow Pages under Metal Finishing (&/or) Polishing for a shop local to you. I spent about 8 hrs polishing just the top part of mine , Let me know what they quote you & I'll think about it.

 

Just placed a phone call to Gotham. (Thanks MAHJIK). Was advised that they send out all their polishing jobs to a local guy in Big D. Said he would call back in a liitle bit with a quote. I'll let you know. Thanks.
