FZR 400 EXHAUST ON A 600

Curious will fzr 400 down pipes fit on a fzr 600 motor ?

No, I don't think they clear well i'm not sure if you can make them fit at all. I think thundercat downpipes fit or modified R6 ones.

Some after-market 400 pipes will fit YZF600 motors and will clear the oil pan, so long as an FZR oil pan was swapped in. Granted the YZF motor has a shorter stroke than FZR, but I believe the deck height is the same due to the longer rods on the YZF. I have no experience fitting FZR400 pipes to FZR600 motors, but given they could work on a YZF600 motor, I would not be surprised if you could massage one onto an FZR600 motor.

No doubt, someone has actually tried this, and hopefully they will chime in.

im curious as to why one would try this? isnt the 400 exhaust system small diameter? wouldnt it be restrictive?

[RoadDogma]

I'm guessing that someone may want to re-use their 400 pipe when swapping in a 600 motor to avoid sourcing another exhaust. As long as the 400 exhaust clears the oil pan, it would be easier to fit under the fairings. I can't speak on the OEM 600 pipe, but had an Ontario 400 pipe with equal diameter tubing to my Yosh 600 pipe.

Well im going to swap a frz 600 motor into my 400 frame, and from what i have seen the stock 600 pipes stick out alot, very close to front tire. I was thinking if the 400 pipes would fit i know they dont go foward so much as the 600s, that was my reasoning, cause not sure what fairing im going to use on this bike yet.

i think the collector/exup hits the underside of the sump and stops them fitting properly at the headers, i know the 600's are way to long for the 400 as a mate had these on his, so would guess they wont fit!

I have a 90 1WG FZR400 with Vance and Hines Supersport exhaust. I just picked up a FZR600 and currently going through the transplant process. I did with no problem, connect the FZR400's Vance and Hines pipes to the FZR600 (93). Therefore the Vance and Hines FZR400 and FZR600 (American models) are interchangeable.
