Instead of ordering an expensive b-pipe to go along with my new y-pipe, I bought a 3in flange & a reducer cone. 3in down to 2.5in. Not a step down but a cone slope down.

I'll have the flange welded to the cone(bought at 2 different web sights), then bolted to the y-pipe & clamped to the end of my stock b-pipe.

Most places I've researched say that 2.5in pipe is plenty for our displacement.

I want to keep my stock muffler & resonator. (like the stock sound)

Flange- $21.50 shipped (Road/race engineering) Cali
reducer- $8.95 shipped (dr .gas) Utah
welding- ~ $5.00

A bit cheaper than a new b-pipe.

 

Great solution! From what I've read, that 3 to 2.5 step-down is a real flow obstructor. The choices for y-pipes with an actual 2.5 connector are few and expensive - most are 3.0. This is a perfect work-around.

What brand of y-pipe is that BTW?

 

eBay special!!! $215 shipped. Pretty good quality, nice welds. I wrapped it in exhaust wrap to help with the sound & heat. Also did the cat pipes with the wrap.

 

had my exhaust put in today. Alittle tinny(rasp) at 4100-4300rpm's that's it. We'll see if it goes away after a week or so.

also had crank pully installed too.

 

great information! Can you suply the websites to order these parts from?

or ill just get my google going

 

in the first post I listed the names of the 2 companies. Sorry, I don't have their web addresses handy.

 

After I installed my UT Ypipe (3" outlet) I experienced that same tinny raspiness but at around 1800 - 2000. But after I put the Fuji on it went away.

 

do you have any larger pics of your creation installed?

Nice thread! How did you account for the extra pipe length due to the reducer flange? I'm thinking about doing a y-pipe/stock exhaust too, but don't want these fitment issues. Any troubles there? Any vibrations? Thank!

Well done baileyrx, nice to see someone doing the right thing and making it happen way to go man.

 

baileyrx,

Thanks for the info. Tremendous help. I just got of the phone with Chuck @ Dr.Gas. They can do the whole thing together: cone+flange+welding for around $35.

I'm going to make final measurements today to make sure their flange (it is 4 1/2" from center to center of the bolt) will fit my y-pipe and than place an order. Now I need coupe mid-pipe

 

just echoing crazymike - is the extra flange a 'non-issue' to the overall length? i imagine there should be enough play with the fujitsubo style y-pipe because of it's flex sections. just checking to be sure.

 

do you think he is willing to make a few more for distribution? i can almost smell a group buy coming on.

 

which y-pipes is this necessary with? i thought the fuji y-pipe was just a straight bolt-on..
