Morning women,

My mate bought a 1998 impreza the other day, now I'm into legacies so I can only go on what I know form them. Anyway,the cars had bits done like a re map and the turbo has been changed apparently with a 5 inch back box.the geezer selling it said it had a massive down pipe on, which I said must be a three inch. But my mate said a bloke had a look at it and said its a 5 inch down pipe( I doubt he used calipers, probably used his member instead) Is their such a thing as a5inch down pipe ??..?.

Thought it only went from 2.25-2.5-3.0

Hi ive had a few classics and ive never heard of a 5" pipe,nearly all are 2"ish,some I know are 3",but never 5,thats a hell of a size! Maybe someone who's more knowledgeable than me will answer with a definite answer.But 5 is BIG....

Nope never heard of a 5" down pipe unless he's measuring the cat 

he's goto have the wrong end of the stick literally. Three inch is big enough ( that's what she said )

Extra girth is always a good thing :D  

Girth and length is better [emoji51]

I just use my arm instead, looks like nothing's changed on here ..........

I have a funny story but it's too rude to put on here.

Maybe he was measuring the circumference

What the circumference of his arm ;)

Your heading down the right path there haha

Don't think a 5" will fit

He might mean 5" wide at the turbo outlet flange end instead of the bore diameter of the pipe

He may

Very likely, classic imprezas are usually 2" classic foresters are 3"
