I think there is a picture on post #133

A pair of 5" inlet cheap gibson boat mufflers, they knock noise down pretty good and they dont seem to hurt hp too bad although the torque picked up pretty good with them off

Thanks for posting the picture like to see what other people use.

I used to have ggbs on my baja, the bolt and clamp weren't tight enough so one blew off in 100 feet of water at 85 mph so i needed mufflers, ggb wasn't answering there phone so i couldnt get another one so i bought these for 400$. Baja ran 99.5 with and without them, when i sold it i took blower motor out and sold the stainless marine 3s. Had these laying around , norm had some gigantic semi mufflers and flex tube we had to drag out and stick on everytime we dynoed. One day i pulled without his and picked up 20hp on my 502 i was dynoing. I stuck these on the 5" pipes coming off the headers and motor only lost 2 or 3 hp and noise was tolerable so i been running them ever since on the dyno.

Rons tb, i would only consider running one of these if you were using a centrifugal and it made plumbing easier, cost too much hp otherwise.

I thought he had the same one we tried and did not work, but one we tried was a std 4150 style, 3 blade from accel, in testing on LS stuff what you saw with this about right, the victor style intake and 4150TB kicked this ass everytime...

He did, he bought this to try as hes considering using these on his 502

So youre saying the ching chang chit are liars about what their T/B flows?

Ya don't say? LMAO

I didnt buy it, Gimmefuel on here did to test, its a poor copy of the fast which doesn't claim to flow any insane amount to start with!

It was cheap enough to buy for a dyno test. Was considering it for my rebuilds since I was considering procharger them at a later point. Don't know until you try! This one never had flow claims made with it. Hard to find flow data on any brand. Wilson's 105 mm claimed around 1500 cfm. I figured this at a 102 mm should at least break 1000 cfm easily. Apparently not so much! Might work good on a much lesser engine, just not in this 6700 rpm 548 haha! When I do my rebuilds next winter, we will dyno them at Articfriends place. Probably​ slap it on for squits and giggles since I own it already. We also have the 2200 dominator throttle body as well. I am planning 509's staying at or below 6000 rpm with much less cam than this motor we tested.

In research, whether data is good or bad, it is still data and tells a story!
