Hi guys anyone done a tight dump pipe like this before,is it possable?
Would it restrict or be too much heat on the bend?
Any idea's...Thanks,
Joab

its a pain in the ass, but can be done. probably going to have to cheat cut a bend a little bit, or even pie cut it.

do not use aluminum for a tight bend off the turbo like that.

Buy a 5" doughnut from chassis shop , they are exstremely tight & will get what you need done

Why not turn it 90 degrees clockwise? Then rotate your exhaust down?

Ok after looking at it a bit more have decided to turn the turbo a bit to give a smoother exit for the dump pipe.
Thanks for all the replies.

That looks like you have 5-6" at most, the tightest 5" bend I have seen is on a 5" radius but that makes it 7.5" or so to the back of the bend. You will have to cut it and make it work and like Joe said, no aluminum there. I don't think even .120 wall will live.

good luck

Turn the turbo if you can. Even a few degrees will help greatly.

If you can't turn the turbo get a 5"dia 5"CLR stainless tube and miter/pie cut it like the above pic "63vette" posted. They're usually available in 90deg bends and I have them if you need. Aluminum won't live there very long with high exhaust temps.

Yeah your spot on it is a bit over 5" now but the engine is going back another 1.5".
Thanks for all the idea's guys.

whats a 5" stainless doughnut cost? gotta be big bucks id imagine lol

 

[Shearer]

Joe, I don't think they make them in 5". That's why we got the mandrel bends.

 

[prost63vette]

I couldnt find 5" doughnuts so I bought two 5'' J-bends from stainless works for 144.00ea

 

[Joe @ Tempest]

oops i miss read what you said. you said 5" on 5" center line, i just assumed it was a doughnut!

i had to make one of those "style" downpipes on friday in 3". its a pain. take forever to weld too, i always allow the metal to cool before i move to the next spot.

Looks like 0 fun either way, nice job though 63vette.

Yah. A little over 13' of welding on that one dump pipe. No thanks!

Does the O2 sensor work alright that close to the turbo, I was always told at least 12".

I never had any problems so far

When I had my 02 that close to the turbo it would not read right.Had a hell of a time getting it to work till I moved it down the pipe a ways.Every setup is different though.
