Reply to "kit speedster exhaust system and muffler"

As always, there are pros and cons to each exhaust being discussed here. The VS is packaged well, gives the best ground clearance, has great tone (so I'm told) and while it  produces more power than a stock muffler, not being a "true" 4-1 header it does leave hp on the table.

  A conventional (collector straight back) merged header and muffler(s) will make the best power throughout the rpm range with it's primary tubes feeding into the long collector in the correct order to take advantage of the "extractor" effect.  The downside- it hangs down the lowest and sticks out past the bodywork of the car, making it easy to trip/burn yourself on if you're not always looking down.  Different mufflers will give it different sounds, of course.

The sidewinder is a noticeably more compact package than a straight back merged header and makes almost the same power (as the conventional header), but doesn't have quite the ground clearance of the VS.  It's longer than optimal primary tubes (necessary to turn the merged collector sideways) is the reason why it doesn't quite match the straight merged design's power output.  There are different mufflers available as well.

Each of these design's comes in more than 1 tubing size for appropriate sizing to engine displacement so decide what features are most important to you. And Stan, as for that Midwest hooligan roaring around your parts...
