Stebro exhaust on 4kq

[a4kcstq at comcast.net]

Is anybody running the stainless cat-back exhaust from Stebro on a 4kq?  I'd like to go with the stainless for durability but I'm concerned about the noise.  It says 3-4 dB louder.  Any comments on the noise level or sound quality?  I don't want my car to end up sounding like a H*nda Civic.  Other comments on the general quality and fit-up would be good also.  I see I can get the OE replacement from Ansa or Bosal for about 1/2 the price of stainless.  I'm torn...
