custom intake pipe options, not like the others!

[FIBA M - EC17PSE]

So I'm at college as a welder and fabricator and want to try make my own intake pipe! I've got a few ideas but I'm not sure on how injen and other company's get there maf size of the pipe to size it down and at a bend? So I was just thinking of using 2 45deg reducers and a straight pipe! But would this be ok and flow the right amount of air even if its not as good as the injen it would be better then the stocker!

Items would be.:-
Silicone 45deg reducer 102mm - 76mm. (From maf)
76mm straight pipe
Silicone 45deg reducer 76mm - 57mm. (To turbo compressor)

Do you think this will work? I also will have to find away to get the recirc pipe in the upper silicone hose but that's another thing I have to figure out!

If there is another option then please let me know as I can use all the tools at college and have great miller welders and great teachers on hand

The eBay equivalent of the Injen pipe is better than the real piece because it's 1/4 of the price. Pipe is pipe.

If it fits use it and it will work great. Just be sure to recirculate your BOV back into the intake if you are not using speed density or have a GM MAF in blow through mode (post BOV).

i think that would work. it be a good experiment. but pipe is pipe. you can get ebay pipe and try to copy

Forgot about this.

You could try copying this idea

One may still be for sale for $15

Yeah I've been looking at how they make that pipe and cannot seem to find out how they get the bends that way! They must have a custom machine for the sizing of the pipe or a stretching machine! I looked at that option racing pipe but they were out of stock :-( and don't worry I'm not new to these cars I know what to and not to do regarding the BOV ha ha but thanks, I've now decided to go with an S bend pipe 76mm and then reducers that way I can weld a pipe to the S bend and it's much easier, extreme psi and forced performance sell similar products to this. So it must work!

Well will see how mine comes out in the next month.

Thanks

Just weld up some 45* bends, Cut it long ways, and splice in a piece to taper it out to the desired width at the maf. Clean up the welds and add a pipe for the recirc tube. Easy as that.

Then again, its MUCHHH easier to use composites for stuff like this.
