Does anyone know how to get rid of the ugly "pinging" "echoey" noise out of the V6 exhaust?

I have a quality muffler (not an expesive racing one but it does the trick).

It seems to that all V6 seem to make the same sound. Exept for those who spend $500+ on the exhaust.

 

my stock pipes, with mufflers made a deep v8 sound until about 4 thousand rpms. made a lot of people think it was a 305, and several thought it was a 350. hehe. then you pop the hood.

 

Yeah, I haven't had any echo-ey pinging noise either.. what type of muffler are you running?

My car is weird....

I have a stock-sized 2 1/4 inch exhaust, yet my car is seriously louder than any other 2.8 Fbody I have ever seen. I've never figured out why!! As with '85 F-bird, most people think I have an 8 as well. Only a trained ear can tell its a 6....

BTW, I saw a decent '91-'92 RS today with hideous chrome tips, but it sounded really deep like an 8 until he hit 3000 or so...wonder what kind or muffler it was.

I think you're alone with the pinging noise...Mine sounds like a V8. But it also has the stock 350 exhaust on it.

 

I have a flowmaster 80 series and got pulled over bny a California Highway Patrol he said "your exhaust is too loud" i was like its a street legal muffler he chedk under my car to see if it was hooked up it was.. Bet he felt stupid

 

Well

I cannot descride the noise well, but i hear it on most 2.8v6 fbodies I have seen. A guy at a muffler shop told ne I should get a resonator for my exhaust to cut the noise. Does anyone else have a resonator or know if they work?

Resonators take aproximatly 5% of the noise away, all it is is basically 4 inch glasspack. I too have a ticking noise up front, but i think mine is just an exhuast leak.

 

Knight, what's your muffler brand?

I know the "pinging" "echoey" noise you are talking about.Kind of what a 2.8 in a cavalier sounds like.I had that until I gutted my cat.I'm not saying that is what caused it.But it help me lose the noise.If it is time for a new muff try a flowmaster or something close to one.Or put a set of exhaust tips on.
I think they are called supertramps or something like that.They have inserts you can remove to customize your exhaust sound.Or add to.
Just a suggestion.
