How much more expensive is to install a True Dual exhaust assuming it either way... paying for it, or self install...

You think that with a set of Jet Hots and a... Flowmasters or Magnaflow Catback it should sound nice?

 

I've only seen one place online that sold a prefabbed dual exhaust system for our cars and it was expensive. It would probably be cheaper to have a local exhaust shop fab you up something, unless you are fully capable of bending and welding pipe yourself.

Secondly, yeah a set of long tubes and catback will sound pretty good and flow plenty well for most applications. Flowmaster sounds nice as does Magnaflow. I'm a little partial to the magnaflow myself and it is a little quieter if that matters. Theres also the hooker which is a bit deeper sounding than the Magnaflow with dual/dual tips.
