Are the slip in mufflers for Hooker sidepipes required?  Would they be too loud without them?  What about backpressure?  I am looking at installing Hooker headers and sidepipes on my '79.  Thanks

running them straight on a big block is so loud and obnoxious you cant really hear yourself think.  you really get into the realm of being so loud you irritate harley riders.
 
on a small block it wont be as bad...  but will still be very loud.  here is a video of my chassis with straight pipes.
 
 
 
you really should have at least a little backpressure.  I decided to go with the hooker hgh flow mufflers..  basically they take the pipe down from 4" to 3" and have a baffle in them.  still straight through..  still pretty loud.

I have the glass packs in mine, not too loud except with the pedal to the floor they are loud. I wish I had gone with the flow thrus (the ones CTHULHU likes). My buddy has the flow thru and they are nice sounding. They also are the cheapest muffler.

Confused As long as we are on exaust, I am going to put a 2 1/2 in system on my small block 350. Up from the 1 7/8 - 2in. I am trying to stay close to original, with a up grade in H/P. Can I get, is there such a thing as larger O.E.M. RAMS HORN exaust manifolds? I have looked on the C-3 parts site on E-Bay to no avail.   THANKS.   Mark
