Maybe we're not talking about the same mufflers, here's what I used

Here is what my ggb's look like,not the same from what I can tell,Smitty

Tazz, those are the GGB Cyclones and work well on 500hp and under applications. The ones Smitty posted a pic of are the Extremes and work GREAT on most N/A and blown mills. The Extremes are almost twice the price of the Cyclones but worth every penny if you have the HP and don't want to loose it.

We have GGB Extreme 4" clamp ons on the shelf.

And lofty was cool enough to hook me up 2 years ago on them!! Smitty:D

articfriends, you should sell me the extra ones sitting on the chest.

What is available in the Cyclones?

Fionn,

Are the GGB extremes becoming available again? My 4.5's are working out great, but would like to know if I will be able to replace them if I ever have a problem.

I have a photo or two to send you when I get a chance.

Those are the same ones that are on my boat (from my file photos while I was installing the ext box last year),Sorry,Smitty

Can't blame a guy for trying.

I thought they looked too restrictive, but they were bought for a 1000hp blower motor application so i figured i'd try them, i guess they sold him the wrong stuff.
