Do you guys see any top end speed / rpm loss with the turndowns?


I dyno'd with and without my GGB mufflers and turndowns at Full Throttle Marine and saw absolutely NO power loss!! :D

I only need 2, how much???

There is a great possibility that I would buy the other two if this would help the sell??

My transom will not allow the same size on all four tips :(
If I can find someone to make the other two I am game for this purchase!

Thanks

Old School, you up for this type of transaction?


Pantera28-650HP, can you price out a pair for me custom lenghts?
You will have to wait until after 8pm tonight for me to take actaul measurements.

I could only HOPE that with the stock Y-pipe, Teague Mufflers AND these turndowns that I would be quiet enough to supress the MN/WI hearing impaired residents! :)

Hugh and Larry,
That's cool by me $250 each + shipping (Probably $20 each). PM me your phone #'s addresses and I'll call you guys this afternoon. I will be in meetings from 10 until 3:30... I would like to talk to each of you personally to be sure that these are what you need before sending them out.:)

I can ship them out tomorrow.

Thanks Craig! :)

I will check tonight to 'make sure' that these will get low enough for my outside ports.
When I have that info as well I want to call Gibson to make sure they can make me a custom set to go on the inside tips :(
I am really not liking what it will do to my swim step usage, but at least it will help keep Johny Law tapping on someone else's fiberglass!

That's cool. Here is the model #. You can get the specs from Gibson's website.

Craig, i had the GF do a measurement this morning since I forgot about it :(
Seems like the tips will only be in the water be an inch or two, you think this would be enough?

How do the turn-downed tips work if there are no internal flappers on the exhaust? If the boat is at rest and rocking in large swells, will it push water back up into the exhaust?

sorry for the intrusion. I would like to know who sells GGB turn down tips? they don't turn 90 degrees down like the gibson tips do. these would work great on the two outside pipes with the hydraulic steering.
thanks for the help. Steve :evilb::cool-smiley-027:
