I do have to say, I'm not a fan of the Escape. Not the height of the ws, but the angle. Though the one you had still caught the eye.

You have the side holes, so not sure. Check Rexmar. I have Gaffrig pneumatic switching tips that use a second flapper to direct the flow through small holes in the bottom of tips. Makes little difference on top, no difference at idle because tips are under water anyway, but some at mid range where tips are just above water line. I like that they are switchable, but they don't make enough difference in my mind. I think the slip ins work with any tip. You may have to remove the tip to install.

You can get some slip in mufflers and insert them inside the boat in the rubber hose. Dana makes some that I've dyno'd with no power loss to 600 HP and only about 25 hp at 800 HP. They take the bite out of the exhaust noise.

I dont have any rubber hose on my exhaust so it won't be easy to install mufflers inside. I am not sure if the standard slip in exhaust will work because the corner /side exhaust doesn't look round. I guess I will have to kae a closer look when I get it out of storage for the winter.

OH, forgot a 525. They will not fit from the outside. Possibly there is room if you remove the tails and try to fit them in where they attach to the tips. They will slide inside the cmi tails if there is enough straight area before the turn into the tip. The mufflers are about 8" long. I don't have one here to look at
