Jassman, We just put a couple sets of GGB Extremes on my friends rig. He's got a pair of blown 900hp mills in a Warlock Cat. He has dry Stellings and the thing is deafening loud! We didn't put a dB meter on it but it's made it much much quieter. He says he can't notice any performance loss and is happy with the results.

Lofty,
Can you send the data we talked about a week or two back (test results).

Thanks,
Rick

I just got GGB's. I'll let the group know how they turn out. I was at 97db at idle before, i'll measure and see how they do.

BTW, O Neil Offshore has amazing customer service. I would highly recommend them...

Thanks, Madmax! We aim to please

rv, I haven't forgotten you I've just been on the run since I got back to town. I'll get it to you this week.

Thanks Lofty, I will let TMP know. Jeff

Neither be loud and nasty and just pay the $100 noise ticket.

They ding you a hundy in Cuba?!?!?!

And they flushed my Koran down the head... Damn Americans white devils.

Semper Fi, I installed Gibsons on my modified 496 HO and they are quieter than my former Corsa's. I don't have a frame of reference before and after because I modified the engine. What engine(s) are you running that were affected so much by the mufflers?

I am also looking for mufflers,was looking at ggb's but the extremes say they are for dry exhaust,my new exhaust is 5" but adds water near tail,its supposed to be wet (don't have the tails YET so i haven't actually seen),what will work best with 950 hp blower motor,Smitty
