Default Audi 90 - glasspack or flowmaster?

I tired to make my audi 90 12v 2.8 v6 sound better by removing the resonator and replacing it with a straight pipe. It sounds good but when you rev it the stock muffler sounds like a beehive. I want to replace it. I work in an exhaust shop and my boss offered me a discount on a flowmaster muffler. But I don't know what would sound better. A flowmaster or a straight thru glasspack?

Thnx

ok i used the flowmaster. I also used a glasspack with it. It's a straight shot resonator with a flowmaster 40. I took it out with just the flowmaster and it was so loud it was retarded. I added the glasspack and that helped a lot. The only problem with it now is that it has this harmonic "howl" when it idles. I'm gonna make a small silencer to help get rid of that howl, but other than that, it sounds amazing. A little american muscle meets the autobahn, its really cool.

Gee, you need to make a resonator. Seems perhaps the guys with the engineering degrees actually knew what they were doing. Imagiine!
If you want to have a nice sound try larger exhaust tubing and use a muffler and catalytic converter from a more powerful Audi that will allow increased flow. Any glasspack muffler will need regular re-packing. What is wrong with a good quality stock muffler from a larger Audi?Better yet buya replacementfrom Walker Muffler with openings the size you need, then run2 1/2 or 3inch exhaust tubing all the way back with a resonator. This will give a deep sound without being obnoxious. Just an idea.

I love the sound of Flowmaster's. If you went back to stock pipes and resonators, the Flowmaster alone will probably give a great sound.
