Ordered up a loudmouth 2 from ebay and corsa clone tips from Chrome and Performance. Any tips on installng this myself or would I be better off taking it to Randys in Marysville.

 

They should come with instructions for the install and a catback is really not hard to install at all.........just unbolt the original (or whatever is on there now) and follow the directions to put the new one on........I don't know squat about working on cars and I did mine........and it mostly works.
