horrible stock up pipe

[Turbogn86]

never knew they got this bad... i got to looking at my friends up pipe off his 86' GN and he asked to swap and i figured he wanted mine for some BOV experiment, but i looked at his when he was done swapping and well this is what i found. he gained 4 psi by switching to my stock up pipe.

Um, perhaps I haven't been around the block as many times as some other members here, but I have never seen a stock up-pipe that looked like that.

My stock up pipe looked nothing like that one.

[Racer X]

Are you sure that's stock?

Thats actually a rare collecter up pipe  :rofl; J/K. But there were GN's/ttypes that had up pipes like that. I forget the story behind it but yes, some cars had thoes up pipes.

That's disgusting, the pipe rather...

the story is that in mid to late 86 the GM pipe bending machines were going "bad" and the pipes progressively got worse, and some ended up like the one i showed u. and some are hardly noticeable. thats whats in kirbans book anyways. mine had ripples but hardly noticeable.

That's what happens when pipe is bent without a mandrel.

I think thats what happens to your up pipe when it
is barely used and gets old.  :rofl;

Actually, I have seen that before. It was likely a cost cutting
measure.

yall should check out the kirban books, tells ya alot of things about these cars that most people dont know.
