Well, I have no idea what cars you work on for a living, but you have no idea what you are talking about on this topic. We looked at many different exhausts for my wifes Stang, the one that sounded great, and wasnt a 700
Borla or Bassani system, was the muffler delete system. The converters on the Mustangs have enough baffling if you will, that taking the mufflers off in turn doesnt make it sound "Cheap" like you think. In fact the custom exhaust place that I have been taking my vehicles to for years, the same place my father in law takes all his hot rods too for 30 years, stated he was surprised on how awesome the car sounded by just taking the mufflers off. It sounds great at idle and tremendous when you get on it, with just a little popping on deceleration.....like a hot rod should sound!! Dont be too quick to judge without hearing it first. There are a couple of You Tube videos that show what it sounds like, you might wanna check it out. And maybe you just dont like the sound of a hotrod, I dont know. Different strokes for different folks. But it doesnt sound cheap at all!!
