Soon enough I'll have a little bit of cash (been slooow just saving up $400 with a pregnant wife). for under $400 I can pick up a set of either Cobra Speedster Longs or Cobra Speedster Slashdowns. I LOVE the sound of Powershots but I can't afford them. What's the opinion on what sounds better between either of these Cobra exhausts? Youtube sound clips never really sound accurate or do justice.
