I have a Cobb TBE and yes, they are too expensive. Got mine to celebrate ex-wife's re-marriage and I wanted to blow money on something previously unattainable. However, the quality is A+++. Fit and finish are perfect and Cobb's muffler tucks in tighter than the stock unit. At certain angles you can see the 3" chrome drain pipe hanging below the undercarriage but no rattles or bumps. I think the sound is awesome, but I'm not sure how much the headers, up-pipe and turbo are influencing it. It's louder than I expected or wanted, but it is a very deep and fierce rumble. Very unique sound.
Both of my girls are too hot for you
