What is the difference between 84 thru 94 mufflersand the 95 thru 05 is it pipe size or length, mount spaceing or what?????


Thanks in advance

Different Size Exhaust Header pipes

 

Just a guess, the older ones are smaller than the newer but how much????

Just to let youknow, Hooker advertises their mufflers for '86-'07 FLH bikes as the same. I believe they all had 1 3/4" dia. head pipes. The only dresser style muffler I recall as being different was for the 1986 FXRD. The mufflers were shorter.

Ok thanks Rini,

I thought they were the same size but couldn't remember... I know the real earlier bikes had like 1 1/2 pipes but that was back in the 60's and 50's...

The early pipes fit together with a flange, the newer ones have a slip fit.

 

I was just looking at the same thinglast night.

I have compared both early and late style and the diameters are the same. The flange at the end is about 1/8" and there is a thread on the forum that explains how a member cut off the flange on the early style to accept late model style slip-ons.

 

When I put Rush mufflers on my 89 EG I had to cut the flange off the head pipes and the muffler for those years has a slightly longer neck on the muffler and they mount with the new torca clamps.

 

I have done a search of the threads but can't find the one you are referring to ....Do you know what thread it is in....????

Thanks

The pipes are the same diameter. The header pipes on the 85-94 models havea flange at the end, just cut it off, remove as little pipe as possible and slip any newer style mufflers on. I'm using the stock H-D clamp. On my '84 I had to change the rail under the saddlebags to accept the new mount. There's really nothing to it. The only tools you'll needare a hacksaw andafile.
