With your setup with the Corsa, there is not much to do because it is already as good as you can get. Free flowing and no resonance, if you add cutouts it may cause some resonance. I dont know anymore, I might just take the chance and see how it works! I just love the idea of a open, loud, and free flowing exhaust on demand and then quiet for when you have a headache or drive late at night...

Happy Thanksgiving!

I just went with a Borla system on my 84 and noticed a difference immediately.  Great sound,  more power and didnt break the bank.  Too bad the weather has been lousy the last week and havent had it out much.

Vette(s): one ea. 1996 LT1, red on gray interior, stroker 383 Dart heads w/ 2.02"int,1.60exeh 11.8:1, Comp Cam 230/236@50 .570/.576 113LSA , Crane 1.6:1`rocker arms, GM Delphi roller lifters HiFlo Cats, Xpipe and low restriction muffles, it sounds lumpy at idle!!!
I enjoy this forum, everyone seems to be be driving their C4(s). I installed JB shorty headers along with HiFlo CATS, a DynoMax system w/ Xpipes and their glass pack mufflers. What I perfered was the original rectangular black tips. the system eleminates the resonator. There is a bit more sound inside. The outside has a nice rumble, but not to sharp. The cost is half of the major brands. You all would enjoy the sound of a cammed up 383 LT, it has a nice lope to it now. JRB

I run LPE Signature Series Headers with a Borla rear Y pipe, Borla mufflers and the Borla round tips.  Love the sound and the performance from them.

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.

Vette(s): 1991 black coupe, tan interior, few upgrades done and few more pending.
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.
