I am thinking of doing this exhaust upgrade over the winter for next season. Any opinions,comments or results would be welcomed and appriciated.............E

I personally don't believe the performance per dollar is there on heavier twin boats from all I've heard. I seem to see the largest gains in performance on lighter singles.

Say you (or I) go this route on our 353's...and net 3 MPH

I don't know today's pricing but 2500.00++ per mph for 2 sets?

I'd do EVERYTHING I could with props first for less coin.

Or for a few K more see Raylar's upgrades.

This is strictly my opinion.

I've been considering them for my 35 Fountain but am hesitant to lose my Silent Choice. Sound laws appear to be getting tougher...

... I understood the gain to be 60 hp a side. Possible 4 plus MPH increase.

However, I was also quoted well over $11,000 for 2 sets fully installed by a recognized engine builder in Orange County.

yeeeaaa....that's performance bargain!

$ 11,000.00 installed? That's outrageous. If we can help, please let us know. We can provide real pricing, dyno sheets and product information if you like.

Thank you.

As clairification, I was told that my piticular boat was a tough install and labor intensive...

Even if you you had to R&R the engines, it shouldn't cost that much. That's over $ 3,000.00 in labor!! Who gets $ 1,500.00 per engine to R&R? I need that business.
