I selected the RS Barn system and am quite happy with it. We ditched the CAT at the same time (which likely makes my system a bit louder). I really like the way it makes noise on throttle, but doesn't seem to drone on the highway.
That's my 2 cents.

I have a 3" exhaust from the cat back (that's why they call it that) to a MagnaFlow muffler. I did eliminate the resonator box. It's loud but I love it and it cost me about $750.

2nd on the RSBarn. Fits great, sounds great, drops 30+ lbs. and no drone. It is louder than stock though, and not by a little, but makes the car sound "proper" in my opinion.

+1 for RS Barn...I have a resonator and only slightly (but nicely) louder than stock. Weight reduction and reliable tested backpressure so no loss in Torque or HP (and we all hate losing torque and HP)...
BY the Way...for $4K I think you could do the whole RS Barn Header, exhaust, chip, etc...

[quote name='rustech' post='36720' date='Jun 9 2007, 10:00 PM']Bob, no it can't go into open loop do to lack of exhaust heat either. Something must be wrong with your car.[/quote]
I haven't looked at it yet (no need so far) but if our O2 sensor is 3 wire, then it has its own heater built in to get it working faster at start up so this would not be an issue.
To comment on the rattle; when the system is cold hit the cat/muffler with a rubber hammer and see what rattles where, maybe it's just a heat shield thats lost a spot weld?

Interesting, I wonder if a different sensor from another application might work better with the config?

Must also add that the B & B has a history of Cracking Pipes...
And...RS Barn develops parts exclusively for our 968 (gotta support Performance Engineers dedicated to our cars or they will disappear).

My B&B was so beautifully made that it would pass for a work of art...and it works absolutely wonderful as the sweetest sounding muffler I could ever hope for. Still looks new after. 1.5 years and, performance aside, the sound makes for a sophisticated sports car. The stock 968 stock muffler simply didn't do it for me. With stock exhaust, i don't find the 968 to be an interesting drive.
If you can find a better aftermarket custom muffler system, at any price, I would strongly encourage you to buy it. Sound may vary from make to make, and performance may vary a bit, but your car will absolutely sound better. I think the muffler total bypass route makes for a 968 that's not really street friendly (Note: although the rear muffler bypass works great on the 928...it's not really a power booster but the sound is wonderful).
But don't base your decision on an in-your-face endorsement of any single braggart with an obvious bias. Check around. B&B or RSBarn, either sound is way better than stock. Performance? Get the wrong pipe size or flow characteristic and your performance actually can be worse than stock.
