How close to headers can muffler be?

The 383 stroker I'm putting the cherry bombs on will go on hedman headers. How close can they be?I'd like to be a foot from collector. Thoughts?

PS. I remember these things dumping their guts early in life way back when. Is it still the case and will being that close be worse?

closer will make them wear faster (its hotter), you'll have to tune it on a dyno to find optimal placement, I'd go about 2 feet, muffler, dumped to the side. Its cheap and easy.

Some mufflers are inside the headers...

When i was a lot younger and asked a lot of questions (maybe 13 years old).. I was told by a guy that built hot rods that if you take a crayon and mark your exhaust pipes from the collectors as far back as you can, then start the engine for a few min, shut the engine back off, then check to see how far back the crayon melted, the crayon mark would let you know where you should place you mufflers..

I dont know if this is true or not..

less power , no back pressure .
i ran glass till a man offered his turbo's for free to see the difference .
i even ran straight header , even more loss
he was right , but it may be type motor build .
also noticed i could hear better .

cherry bombs actully increase exhaust turbulance because of the way the fiberglass is courogated.. thrush magnum glasspacks are diffrent using the perforated tube which works much better

i second, i put packs from the rear of headers, and yes it was loud. but like??muffled loud? ( not the best sound ) also, my 350 did seem to lose some power, maybe they were so loud the sound just didnt match the power? dont get me wrong, i LOVE loud cars, but glass packs to me, got kinda a dirty sound. i couldnt even hear my headers

I'd say the worst exhaust sound from a v8 would be a v8 pickup with glasspacks and big chrome echo tips out the back!

The best bang for the buck would probably be Dynomax turbos..
