I was in same situation a few months ago and went the Stainless Works LT route. Got it groupbuy with highflow cats. LTs and High flow cats bolted right up to my Solo Mach XL exhaust. Its not loud at all when cruising, but sounds like a muscle car. Open her up and WOW!!!!!!!!!! I have a few vids of sound from in cabin and behind car. I have a vid of cruising in cabin with radio on pretty low and you can barely hear the headers just to give you an ideas of exhaust volume.
