This is stock L98 headers, down into twin 2.5 inch cats, into twin 2.5 inch pipes with balance pipe and DynoMAX 2.5 inch straight through mufflers. Was all done custom though, not a pre-fabricated system.

Loud-ish, but not over loud. Depends on your tastes

If it is I'm thinking I would probably lose too much backpressure and low end torque. An yinput would be appreciated.
I have the B&B 3-inch on my '94 6-speed w/345 gears. My car is otherwise stock mechanically (has the original manifolds and cats, stock cam/heads, etc). I love everything about the B&B except for the resonance that occurs from just off idle to just below 2k RPM. The resonance in that range is really strong, and will flat wear you out if you try to cruise in that range. I've learned to avoid cruising below ~2k RPM to prevent this.
I've heard (but can't confirm) that B&B made a change to the system at some point in its production life, and that the newer system has less resonance -- but confirm this with B&B before you buy, if you care about the resonance.
A Forum member posted a very clever roll-your-own solution to the resonance on the B&B system, but I haven't tried it myself -- you can find it here:

I think the B&B system is very well made overall.
Be well,
