    If you are looking for the loudest go with a single muffler If you have duals you split 4 cylinders to each muffler instead of forcing all 8 through one.
    If you have a "dumped" muffler it also is louder than "pipes" out the back because it does not have the 3 or so feet to loose some of that sound.

    A "true dual" is NOT 4 cylinders a side, it has a cross over or H pipe some where so that it equalizes the sound a dual in-dual out muffler will do the same thing as ling as you have two cats and the pipes never go into one. Suburbans come this way from the factory but then it goes to a single 3" pipe. And to get an H pipe exhaust done it is usually pretty expensive even at a custom shop

    well technically a "true dual straight pipe" exhaust means that the exhaust pipe comes off of both headers, then travels to a X pipe and then out the rear or sides with no muffler.

    thats what it means where im from and thats what i have...hope that helps..

    Straight pipe down here means you have ither your muffler or cat or both removed.
    Its mostly common on older trucks and diesels.
