STUPID QUESTION - What is Resonance?
I an a new '02 Coupe A4 owner, and I'd like to "beef-up" my exhaust. However, I read several threads mentioning "resonance," especially as it relates to A4 transmissions.
First, what exactly is resonance? Also, why does it apply more to A4's than MN6's? Finally, does anyone have the Stingers on an A4? How do they sound?
Thanks!!! :cheers:

The responce I recieved from a supporting vendor stated this about the borla stingers...
"on a manual, little to none, on an automatic horrible."

Re: STUPID QUESTION - What is Resonance? (COOL COUPE)
Resonance occurs between 1,800-2,200 rmps. Its a droning buzzing type of sound inside the car. Its usually worse on A4's because you can't control the RMP's at which you cruise as you can in a manual car. I'm sure there is someone with the stingers on an A4 that will chime in.

Re: STUPID QUESTION - What is Resonance? (omrossi)
Thanks, guys. Anyone with an A4 and Stingers?
Also, I'm not looking to wake the neighbors, and my C5 is a daily driver. What exhaust is reasonably priced, and sounds great on an A4 (with no resonance)?

That said, if you are happy with the stock exhaust's resonance (it does, you know) then stick with it. Any after market system that is louder than stock runs the risk of "resonating" the car body at some particular frequency where it's resonant. But, if you want your car to sound decent, you need to get rid of the stock system. The louder after market systems all resonate the car's body at its sympathetic frequencies. Some pass more energy at those frequencies than others. Corsas have little output below about 2500, so they resonate least. They also sound make Vettes sound like they're running a 3.5L instead of a 5.7L engine. If you like the sound of high-winding Eurocars, you'll like Corsa Indy's. If you want your car to sound more like NASCAR, buy something else. I've heard a lot of systems, but none comes close to the Stingers, overall. My A4 with 3.15 has no unpleasant resonances. They are all quite pleasant, thank you. :D

Re: STUPID QUESTION - What is Resonance? (Anth)
There is some minor resonance at about 1700-1900 for me, but it is only at maybe 1/3 throttle. However, ther are no regrets here. I love the Stingers.

Re: STUPID QUESTION - What is Resonance? (omrossi)
Nothing really new to add...only my experience. I LOVE MY STINGERS!. They're not as loud as some have indicated on my '01 A4 at less than wot, maybe due to the precats. There's little if any resonance and if/when I think I hear some, it's only on very cold start-up (overnight). I like that now I can rev the engine and not be embarrased. Also, prior to the Stingers, I couldn't hear the exhaust decelerating in 4th. Now I know it's there and that's a good thing!Also, I resisted at first thinking I couldn't live without 4 tips. Now I wouldn't have it any other way. Put be down as one very happy Stinger owner :yesnod:
