Dlank and I werent able to cross paths this weekend, but I did measure the slip. The heat would stick out about 2.5ft from the end of the dock, the last foot or so would stick out beyond the roof. I forgot to see what the length would be like trying to back out of the slip.

I must say I do not understand your post. "Silent choice is the worst thing you can put in" ????? My Rage has silent choice and I think it is the single BEST thing I have put on my boat and I have lots of options on my Rage-Whipple, tabs, hydraulic steering, CMI headers etc. I run mine closed all the time except when I am going really fast.

What's so hard to understand? Silent choice exhaust isn't designed for performance boats as it increases the chance of reversion 10 fold. You must own a rage that exits the exhaust out the corners above the water line. Sure, silent choice is nice for canceling noise (if your exhaust is above the water line and you don't have an aggressive camshaft). If it's the under water exit, there is no reason to run silent choice as the water muffles things at idle. And under way/WOT we all know how awesome silent choice is....

I was trying to be polite, but from your reply I can see that is not in your nature.

Never argue with an idiot. They will drag you down to their level and then defeat you with experience.

I have silent choice for 10yrs then Corsa electric 10 more years never a water issue with either one!I also thought the same way but long time Marina owner woke me up.If you choose to wire them open so be it??:confused:

Oh Jesus..... You need to relax and take a midol. If you were offended that's your issue, not mine, as that wasn't my intent. Silent choice is the number one cause of reversion. It's been proven over and over by people with years of marine Performace experience. Do you realize many here don't even know they have reversion, as they have been lucky, and also never taken the time to confirm, ie remove a manifold!?

I'm an idiot, and you sir are a prick!

Switchable exhaust systems other than silent choice/mufflers might be many times more expensive, but are a much better option than a true silent choice which utilizes a y pipe and can increase the potential to revert at idle with a camshaft with too much overlap. You won't find any Performace camshaft company who endorses the use of "silent choice". Other switchable systems/mufflers, sometimes, yes, but there are many factors that contribute to reversion.

If you like silent choice and don't have any reversion issues with your particular setup, great use it. However, it's not a system designed for a Performace marine application. Just because your system doesn't revert(most blown apps don't revert by nature) doesn't mean it's the optimal system. Again, many Rages/heats exit the exhaust below the water line, so muffling at idle is a non issue. Once on plane the swimstep helps to mitigate some noise, and who in their right mind would run silent choice at WOT in a "performance" boat!? Granted at that point there is no chance of reversion, but flow is severely impacted.

Calm down you two... take it to PM if you want to throw insults back and forth.

I honestly prefer a loud boat, but that is just me. A lot of lakes in Texas are adopting the 92 decibel limit, which is ghey, but the lakes I frequent have not started yet so I am good.

OP, glad you got to take a Rage run. Offer still stands for a Heat run if you want.

Guys, there really shuldn't be a controversy here.......
I've run Teague ST450s on my heavily modified "575" for years.
I've never had any isues with them at all. Like most performance boaters, I love the sound of big horsepower
engines at any speed, idle, midrange, WOT. My cam isn't exactly stock either........:) I don't use them much, but I do consider my fellow
boaters and marina slip boat owners/operators. I don't want to come off as "that ******* with the load boat". We have one lake here
(Center Hill) where fun police are trying a noise crackdown. I just flip them on when they are around and they never say anything.
Even I get tired of the racket sometimes after a long day on the water. It's a nice option to have.
Peace out,
Steve

Steve,

I couldn't agree more. However I'm referring to the silent choice that utilizes a Y pipe. Switchable is a great option indeed.

Borgie,
When people say silent choice, they may (?) actually be referring to that particular muffling system.
However, they may be referring to any switchable system as well. People have referred to my setup
as silent choice. It's like Kleenex or Aspirin..it's become a generic term.
BTW, a good friend of mine with a 29' Fountain and factory installed 575 with Merc/CMIs actually has
Merc silent choice. If it's ever had reversion issues, we've never noticed it, and I doubt Fountain and
Mercury would do it because of warranty headaches. Another friend has the same boat with a 525 and
Merc/CMI "sweeper" headers and Merc silent choice. Again no issues that we have detected.
There are multiple causes of reversion, usually an agressive cam profile with a lot duration and/or overlap,
combined with an exhaust system that is not designed for that cam profile. I would agree with you that
a custom engine that is on the bubble already with a certain cam/exhaust system could have reversion exaggerated
with the introduction of a restriction in the exhaust system, of any type. Of course then, which came first, the chicken or
the egg..........a motor/cam/exhaust combination prone to reversion, or an exhaust muffling system?
Regarding exhaust noise in general, whether we like it or not, and I think most of us do, if we don't police ourselves,
eventually the real police probably will.
