Rat,I'm running a titch under 950 hp with 5"ggb's with water added right at the tips of pipes. Boat goes EXACTLY same at wot with or without,actually idles BETTER with the mufflers on.The i.d looks real small,like 3 1/2 or 4",GPM ordered some for his 1350hp blower motor and felt they were too restrictive and sent them back but he's the only one I ever heard that wasn't happy,Smitty

Ratman,you might have misunderstood what I meant,my water is added at tips of the pipes (which is inside the muffler) so I'm running the mufflers wet. Might get boat out saturday if this warm weather holds,Smitty

Smitty, after waiting 9 months for the special order mufflers not to show up, I had to keep the 4.5s that Grahm sent. I was leaving on vacation and didn't want to get thrown off the lake. I never cranked the motor all the way to see what happened on top end, but I did see a 200 degree increase in exhaust temp by 6000 rpm with the mufflers installed. I used to have pictures of the inside, the 4.5 was pinched down to 3.5 or 3.25 ID. Graham would have taken them back all I had to do is pay the shipping both ways.
