Y-Pipe Project..... 3vz-fe

[wontonjohnny]

so after making my CAI with mandrel pipes, i feel confident enough with my welding to make a Ypipe.

CAI thread can be viewed here

look at this piece, the flattened area's cross section cant be any greater than 3.14^2 inches from what i can see,
we will all find out when i cut it


made this y colector today

2 x 2 inch in
2.5 inch out


havent cut anything yet,

good job dude, looks like you can do it

[Toysrme]

Good luck! Lemmie know when you're ready to weld up 3 sets of headers that can hold a T3/T4 hybrid.

[SlingShot]

no company makes a y pipe for us?

[Jzs147-RR]

I have one in the works right now in 2 sizes 2.5inch and 3inch with test pipe or cat.BTW be carefull how low that sucker hangs because I already lost my test unit when I hit a pot hole lol ..War zone here im telling you.

[2wickedtoyz]

nice i was thinking of doing the same but i got no time to do it. keep us updated

[wontonjohnny]

update


here is sections of the old ypipe cut up



^ that is the flattened section, you can see that the spot where i cut it has a diameter of 2 inchs, so i would predict that the narrowest part (4 inches above the cut) is about 1.75 inches in diameter.


^ This is the collector section... its got wierd flutes in it.


now the good stuff


^ most of the joints are only tacked on, will finish up probably tm after work.



Straight through FLOWWWWWW

Very nice, now make some headers too
I've been thinking about one of those little welders, how are you liking it?

[Luckynumber5]

how did you learn to weld? i am very interested in learning!

[robehsi]

Nice work man. Let us know how much you gain! I am going to perform this mod also (not myself, custom from a shop with a mandrel bender) along with some custom headers. Pretty soon here Im gonna p&p everything and rebuild with an import performance kit aswell as bigger injecters/fuel pump/msd ignition etc etc the works. A turbo setup is certainly in my future but I wanna see what kind of gains I get first from everything else first. Keep up the good work.

The best way to learn is to take a welding class.

I took welding in college. One of the best classes I've ever taken.

[wontonjohnny]

lucky,

im self tought

jsut read how to's on the net, practiced on scrap, its not that hard.

[Luckynumber5]

i gotta try this, should i start with mig or tig? i think i remember a friend saying tig was easiest to start with but mig makes a better weld or something

[Ne0z31]

dude, thats awsome, and yes, its unbelievable that toyota would make such a shitty piece on one of thier cars...
