brenspeed said the sound should be between stock and off road.

Don't worry about the sound IMO it won't be much different between the two and will burn off the smell sooooo much better. It will probably sound a bit deeper with the cats.. mine does.

Had a O/R X pipe on for only a week! couldnt stand the smell or the trumpeting. if i let it warm up in the driveway for 5 or 10 mins...you could smell it all through the house...nasty! hi-flows are much better , not as loud... but still double the factory cats...and no smell !!!

I would do high flow cats. Probably just as loud as no cats. You would need a Db to check the difference but as smokestang said the smell is gone and as the trumpeting. I still have a little trumpeting, but not as bad. Don't get me wrong, my set-up sounded awesome w/o cats, but the refinement and lack of smell made it worth it to go with high flow cats.
