Went through the research about a year ago.  Came down to the tips.  I went the the Corsa.  Love the look and the sound.

Check out the red corvette 1990 standard convertible stock system and changed to a Magna Flow cat back system 15658 with 3.5" tips quad mufflers on corvetteguys.com click on exhaust then click on C4 scroll down to my video. They are louder than stock with a low range throaty sound. They also have have been dyno tested to improve Hp by 16.5 and torque by 13.

I have had my 1991 about a year. It has a full magnaflow system with skinny little bullet mufflers and high flow cats. It was impossible to have any sort of conversation inside the car. Flowmaster 50 claimed to lessen the inside volume. With those it is still loud inside with drone being improved but still significant. Something with less drone would be a good thing. I don't know where to go from here either. Increased the wattage of the alpine amp but that is not a fix.

Make sure your tips stick out beyond your bumper. I just made that adjustment on mine and it made world of difference.

I have Corvette Centrals "H" pipe true duels (cat-delete) coming out to Mid America Motorworks Quad Power Mufflers on a stock '89 L98.  Very free flowing.  Is loud but sounds great.

Mt 91 had a full Magnaflow on it when I bought it, including hi flow cats. Great sound but loud, you cannot have a conversation in the car. Switched the straight through bullet like mufflers to Flowmaster 50s'. Lesser tone but just as loud and just as much drone. That was $250 wasted. I may end up going back to stock mufflers, with the hi-flow cats, it'll probably still be a little louder than stock but easier to live with than what I have now.

My '87 has simply got a dual 60mm s/s pipe system all the way from the stock headers out to two small boxes at the ends which are sleeved to negate their effect, no cats or other restrictive items. Its sounds great and idles nicely. Driving, its quiet enough that I can hardly hear it even with the roof off, but with a free flow filter etc, it'll waken the dead with an awesome V8 soundtrack when I tach it up.. No drone either at any speed. In fact, at a car show, I won the best exhaust note beating a new MB 6.3 V12 gullwing complete with its stock cutouts!!
