Anybody use a muffler instead of a converter test pipe?

Am getting a deal on a Flowmaster cat-back for my '94, and want to yank off the converter at the same time. However, I'm not sure I want it THAT loud (I must be getting old!). I was thinking of welding a Dynomax Bullet muffler in it's place. Anybody done something similar? Thanks,

I did something pretty similar

Highly recomend that. The dynomax will only make a minor difference in volume though. It will greatly improve the sound quality though by getting rid of the raspy tin sounds. I have soundclips on my page of the bullet vs the highflow cat, but not of the straight pipe because it sounded so bad i didn't feel like putting it back in just to make a sound clip.

Yep here's a couple pics of a bullet in place of the cat. http://z28roc.cz28.com/Bullet.jpg

It will make a big difference. A resonator up front helps the muffler at the back and will sound much better by attenuating the higher frequencies.
