Making My Own Twin Drift Pipes

[chrisfindlay]

Need help with ideas to make this work!


Ok so early this morning (Sneaky time when it was still dark) I drove to my local Exhaust Work Shop, walked around the back, opened the large bin to find a 6" long 3" diameter straight Exhaust Cutoff, and two 6" long 3" Diameter curved Exhaust Cutoff's.. And my plans are to make my own twin drift pipes..

My Ke70 is already running a 3" exhaust - Single pipe, but I want to cut it off about 8" from the rear of the car - Leaving me with a 3" exhaust running almost to the end of my keto without an exhaust tip..

I was wandering how I would go about making my own pipes though (How would I cut and weld them to fit)

My plan is just to cut the left curved pipe at roughly a 60 degree angle, going from the rear centre position of the pipe, across 60degrees to face the right hand pipe, which I would do the exact same cut to but on the opposite side, leaving the cuts facing each other, and leaving two 1.5' halfs at the end, and a full pipe at the beginning..

Then I want to weld the two cuts together, so that the pipes are joined leaving me with a 3" tip, running to two twin 3" pipes.. And then welding the single 3" end, to my 3" Straight pipe, and then my 3" straight pipe to my 3" cut off exhaust.

Looking something like this I guess....



Obviously there wouldnt be a gap in the end of the two pipes facing the exhaust, I just drew it like that, so you could see what my plan was for the angles...

Would this work? Has anyone done anything similar, and does anyone have any better ideas? Thanks.

3 inch is huge for a ke70 to begin with. i dont think you will get any good answer to this question. you will just have to wing it and make a few cuts and see what you have to do to make it work

just have a crack

start cutting and eye ball it

try your best to make the fit as good as possible to make welding it much easier

Chris 3" is massive for a ke..... it will look s13 spec (no offence) but at the moment for the 4k it isnt going to do much..... If you get your smallport running i would suggest 2.25" And im pretty sure your green ke has a 2" or less on it

My ke is running 3" and ill make it work, just you wait..

Cheers bud, going to weld up the tips tomorrow, Ill use an oxy and a coat hanger as filler wire

Unless it's turbo, 3" is too big.

DO THIS WITH 2" or 2.5" pipes, will sound much better

make sure this is only for track use as it is a stupid size pipe for the street and even for a carby on the track

it will be loud, but wont be a pleasant loud like a sr20det with 3" straight pipe

make video of this when your done =D

i pray your joking.....

3 inch on a 4k will most likely make less power than a 2 or 2.25 inch, its to large so the gasses will get stagnant and hang around
