GX690 muffler worth the change?

Been reading on this, still on the fence about switching. Any advice? worth it?

Is your old muffler bad. What are you hoping to gain

I’ve just been reading a lot about people bashing that silver muffler and that sellers cheap out using it. I have no knowledge why or if its true. Why did Honda use both?

Honda doesn’t use both. Pressure pro buys the cheap non oem mufflers that are only held on by 4 stud bolts, no heat shield and a loss if 1.25 horsepower in back flow pressure. Night and day difference between the two.

How about for a 630?

I would always go with what was designed specifically for Honda.

If I upgrade my pump at some point I’ll probably have to get an OEM muffler. Right now the 5.5 that’s on there is under stressing the motor at 17hp.

Excellent point. Ill order one.

They come left or right. Make sure you get the right one. They will last thru two motors.

Oh wow that may be worth it. @Innocentbystander I’m assuming those numbers are from the 690

Under stressing?

Yes. I have one 670 but they are all the same except for carburetion
