No that would be real world testing . Slide rule guys and number crunchers do not go for some thing like before and after witnest by real people. Along, looks like, no more than five in" could be wrong ,but Pac-brake with the spacer and elbow seem to be that long . I have not looked in side the pipe to see if the gas bouncing off the butterly or going round and round or straight out . I think ill ask Pac-brake at there web page . Ill post if any reply . STill can't figure why after putting on my Pac it don't seem to have lost 15 to 30 hp . Just a few thoughts.

IMHO, I think the 15-30hp is coming from removing the silencer-ring... . that's part of the PowerPack now and this new E-brake includes parts to remove this little piece too.

about a thousand posts on the sr should confirm, the only reason that our rams have it vs the other uses of the isb is sound related, not performance. if someone is making removing the silencer ring as a selling point, look into the archives on this, then see if anyone has ever seen a hp gain by taking it off. nope.

well, that was meant as a joke..... nothing serious at all.

WOWZY - sometimes highest flow isn't the ultimate answer. The precoolers on the 777 have flow mixers to help with mixing (obvisouly) because the effectiveness of the heat exchanger is a higher priority than pressure drop... ...

I don't care if they spit-shined the inside smooth as a baby's bottom. You stick anything foreign inside the pipe and you will disrupt the normal flow and raise EGT levels even though most E-Brakes don't cause any EGT threat. But to make a 15-30hp increase claim is pure BS.



I've seen the inside of a stock downpipe and cannot see where any amount of smoothing would even compensate for having the butterfly and stem in there.



The only way that I can see having an Exhaust brake that would disrupt the exhaust flow minimally would be one that closes like a Gate valve and when open would have nothing foreign sticking in the middle of the pipe.



I my opinion based on common sense, Gales claims still don't hold water.

sorry, holeshot, just a little brain-lapse on my part. but you never know.
