V max 4 750 vs 800 exhaust

[J bic]

Greeting,

Can anyone tell me how to visually tell the difference between the 750 and 800 exhaust?
The reason I ask is I am looking to put the 800 exhaust on my 750 for the hp gain. I just want to make sure I'm getting what I paid for.
I apologize if this has been discussed, but I couldn't find a thread on it.

Thanks in advance!

YOU PUT THIS IN WRONG FORUM. DIFFERENCE IS IN THE '' Y'' PIPE. I HAVE SPEC IF YOU CAN MEASURE ONE YOUR LOOKING AT. THIS EXHAUST WILL ADD HP TO THE 750, BUT CHANGE JETTING ALSO TO 800 SPEC . 3:16 (yammie tony)

Relocated to correct forum.

Thanks Tony, I can measure it. What should I be looking for. Again, thanks for the help.

Can't wait to try this sled out!

Sorry Mr. sled, still trying to navigate.

YOU NEED TO MEASURE THE INSIDE DIAMETER OF THE '' Y'' PIPE. ANOTHER WORDS THE END WHERE THE PIPE FITS IN. ALSO, ON THE 800 THE Y-PIPE END IS A MACHINED FLANGE, WHERE THE 750 HAS A FLARED END.
750 - 46.2 mm INSIDE DIAMETER
800 - 48 mm INSIDE DIAMETER
ALSO POSSIBLY YOU MAY FIND A 8BU STAMP ON PIPES. 3:16 (yammie tony)

No stamp but it measures out. Thanks for the lesson!

The inlet pipe on the expansion chambers is also 2mm larger than the 750.
