Find what sound you like and find out what makes it that way..

You can tell that a couple things affect exhaust note - the engine itself of course - compression, cam etc.. then it will depend on pipe diameter, whether you have H or X pipes, plus the mufflers, even straight or downturned exhaust tips if you want to nitpick..

- adding H or X pipes will soften the sharp compression notes.
- muffler sounds are subjective.. I have Flowmasters. They do have a rather loud resonance around 45mph.

Listen to this clip (skip to 0:30 mark) for an example of a 9.4 compression 361 big block, 4bbl, slightly bumped cam, stock manifold, into dual 2in pipes, no H pipe, and Flowmasters... at low idle.

Listen to this clip (skip to 1:30 mark) for a stock 383, 4bbl, stock manifold, into 2" dual pipes, with H pipe, and Flowmasters.. at normal idle.
