I would also have a look at scorpion, whose systems are pretty much the same price as the custom exhaust builders but don't resonate in the cabin nearly as much as a custom build one would.
No offence but it just sounds to me like you went to a poor aftermarket exhaust shop. Any decent shop will work with the customer to create a system that they like and should be able to make recommendations based on your personal requirements.
Sure, if you go and say "give me a new stainless exhaust please!" with no other information such as requesting central and rear silencers, a chambered centre, keep the noise/drone down, nice rasp or a throaty idle etc. then yep, they'll just make something up that may not be suitable (not saying you have done this, but it is a common mistake).
But if you go and say "How much for a cat-back stainless system with a large chambered central silencer and a smaller rear? I'm looking to keep the drone to a minimum and a lovely raspy, almost WRC type exhaust note in the high end". Then they'll come back to you with all sorts of suggestions as for which mufflers you can look at, tubing size, silencer sizes etc.
So I wouldn't rule out a local exhaust shop so long as the OP can give some basic requirements and goes to a place that will work with them to achieve the result and not just slap any old thing on it and call it a day.
