so conservatively call it 80-100 horse for twins- that's got to be good for something- compared to the more intrusive options of the Raylar kit (worthy) and the Whipple SC (also worthy) at a higher expense.

I'd like to see some documented twin results too- but the first ones I see may be my own. something is coming- just not sure how soon (Antbody want to buy a nice Pantera- CMI's included )

I'm sure the CMI's would perform unbelievably on your cat!! Maybe even get you in the record books . . .

8 grand will buy one helluva lot of anodized bezel and powder coated bling... easily making my boat 3 MPH faster at the dock.

right back at 'ya.

(just having fun now...)

Thats why we all look so fast sitting at the docks!!! Good luck with whatever you do. As long as we're having fun doing what we enjoy right?!

I can provide a few names and phone numbers to customers who would be willing to share the results of twin installations.

If you're seriously considering an upgrade of exhaust, give me a call and I'll send you in the right direction for real world numbers from the users mouths. .

Thank You...and absolutely!

Thanks Fred. I would come to you first no question as I have been most pleased with my purchasing experiences from Trick.

I had sold you a pair of flame arrestors for the Mistress before there was a Trick Marine...

hope it wasn't buying accessories from me that drove you to open your own store.

The openings at the header flange are already too big so don't touch them. The biggest problem in in the plenium. No two ports are the same. The manifold's port openings (or exits) are small in the plenium but keep in mind the head uses a 1.720 exhaust valve and a very small exhaust port VS 1.880 for the blue motors. I don't have any AB dyno numbers but what I did was equalize the port dimentions. Use some inside dividers and measure the largest of the center runners and open the smaller one to match. One runner on the end is much bigger than the other so don't try to match you may end up in water. Don't touch the riser or the opening on the manifold. Keep in mind when grinding, the wider you make the ports, the shorter the lenth of the pipe. My guess is there is at least another 20 hp gain if done correctly.

im getting cmi e top re program and new prop on my 07 26 outlaw. Is this a good combo?

If you get all three at the same time how will you know what worked and what did what??

No reprogram of a stock 496 is going to net any real gain unless you raise the rev-limiter and on stock 496 valve train that is like playing Russian roulette with 4 bullets in a six shot clip!
If a prop is not just right for any boat, proper prop rework will usuallly add 1-3 mph on average.
As for the CMI e-tops for the 496 Merc, my info is about 15-20HP max over the pretty good Merc stock exhaust system.

good Luck

Best Regards,
Ray @ Raylar
