I believe B&B are less harsh on the resonance....I will let some other members chime in about this...

The only aftermarket exhaust system that I hear universally praised for no resonance is Corsa. With every other brand (Magnaflow, B&B, Flowmaster, etc) you hear some people say they get no resonance and others say resonance is really bad. I know I have headers, duals, no cats and 40 series Flowmasters and the drone will rattle the fillings out of your teeth.

Corsa is the Only exhaust system that has Great sound and No interior resonance.

It's expensive but, you'll end up replacing every other exhaust system you try before ending up with the Corsa, believe me!

B&B is actually one of the more resonant for the C4...at least in the 3" kit. I think the 2.5" is quieter, but I haven't personally heard that one.

Corsa is the only way to go for no resonance on a C4, all others have some just more or less.

I put Corsa's on last week and am thrilled with how quiet they are while going down the highway.

I have Borla cat back on my 93 lt1 and I hardly notice on the highway:however, around 25-45 mph there is a nice deep hum. I have heard many Corsa kits and they are designed to eliminate the dron in the cabin and when you hammer down the loud pedel the it will change its tone.

Borla and B&B can be bad with resonance, Corsa is the only one I'd go for if I wanted no resonance.

If you want a aftermarket system, Corsa.

The stock mufflers will work fine, too I've got Hedman long tube headers, true dual pipes without any cats and only stock mufflers. It's dead quiet while cruising, the loudest thing is tires in the highway speed. (50-75 mph) But when I step on it, it will have some nice growling. Just the way I wanted. Quiet while driving nicely, but loud enough, when I want it to be.

I used to have Magnaflow mufflers, they created terrible drone, especially with true duals, no cats.

I am not sure what mufflers I have...maybe equate haha,,,anyway I have heard that Corsa is the best...probably go with quiet flow until I get more $$$$. I have more things to do before I spend big $$ for an exhaust...Thanks all for your advice...Thanks everyone

My B&B exhaust had resonance which is why I ditched them for a Corsa setup. If you want a NO drone system, you have only one option - Corsa.
