do you guys know any aftermarket y-pipe that has
an outlet of 2.5" (70mm) instead of 2.75 or 3"?
since i want to avoid the need of the use of cone
reducer ad further welding and cutting

thanks

What middy and end pipe did you plan on using?

 

? stock ? I think that most copy the fuji which is 3.
You can use mismatched pipes, won't sound that bad. My friend had to do that because he put on the rs-r and did not purchase the y-pipe. Sounded good to me. You may want to look into a custom y-pipe.
* edit *
the exit on the hks y-pipe is about 65mm~2.56", 5zigen has a 70mm~2.76" exit, have no clue about the JIC and Top Secret though.

 

I don't think anyone makes a 2.5 anymore.
NFC was the last one & they're no longer in business.

I got mine just b4 they closed shop.

 

Wow, even Kinetix looks like they no longer offer their 65mm diameter Y-pipe. The closest thing to oem pipe diameter is the Tanabe Y-pipe with 70mm pipes. It's got a very nice collector design, more like the Jic.

Using a dial caliper, the oem Y-pipe output does measure 64mm on the inside.

Hi there,

Thanks for the input guys.
right now, i believe i would have to go with a cone reducer ..
to reduce the ypipe outlet to the stock middy inlet size..
(Since no one produces 2.5" outlet ypipe anymore)

however, i have seen quite a few ypipe that has different
outlet size, i.e. fuji has 76mm (3"), tanable has 70mm (2.7")

so, my question would be, is there anyone who has done the
cone reducer thingy..and can show me some pics or more information?

since.. according to my knowledge.. you would have to cut the coupe
middy.. weld on a cone reducer (3" to 2.5") and then weld on a NEW
3" inner diameter flange... (while out stock middy has a 2.5" inner diameter flange..)

once again, sorry for the long question

LIke i said, there is one that you're looking for...

If you put a reducer, you will have to run a custom exhaust or do some cutting as the G exhaust will end up being too long.

 

You're gonna spend the money on a nice 'Y' and not up-grade the rest of your exhaust with a full 'performance' cat-back set-up? Help me out w/this. UBCool, jbx

 

The JIC is 76.3mm
