We've compared two mufflers in search of quiet(er) performance.

*EDIT* Dyno results are in! 443 rwhp and 490 rwtq. Taking into account the 1.5 degrees of timing we added, the mufflers cost NO power. Before we made 422 rwhp and 475 rwtq.

EDIT EDIT: Car has run a best of 10.77 @ 128 so far... still some left in it, though!

EDIT EDIT EDIT: The car turned a 10.55 @ 129.3 and the block and trans let go. A Dart 363 and a built Powerglide are going in!
