But I can see it coming and will have to get them soon or later.When it first bust off with no water its loud.In thr boat the blower whine is louder that the exhaust :evilb:


2001 388 Hustler
It has the CMI's with wet tips stock.
500 efi Whipple 3.3 4.5 pulley 779hp
. 4.0 pulley 867hp

I think the DP is close to a stock 500efi at Idle only

Mufflers are going to suck :mad: :mad:

Re: MUFFLERS...are you using them or not?
 

I have IMCO gatlin mufflers on my 2005 HP525EFI's. I would rather not have any mufflers, but I got them because of the law. I have no idea what dB I am at with these mufflers.

29 Outlaw, 496 Mag HO's. Was 97db at idle without mufflers, got ticket :( Now running GGB Extremes. Sounds good, no more problems....

Sucks having to run them tho, it sounded GREAT without them.....

Re: MUFFLERS...are you using them or not?
 

Yes...I have in-line GGBs on my twin stock 496HOs and did not experience any loss of speed. The boat is much quieter, but still has a great sound.

Re: MUFFLERS...are you using them or not?
 

I have GGB's because of the law. Not sure of the decible level yet. 2006 Dragon 39.
