B&B bullets just installed! WOW!!!!
Well I just got my bullets in this morning and of course had to run immediately to the dealer for install.I had Angel do the install at the chevy dealer in Hallandale where they have a dept for performance vettes.The install only took about a half hour and it looks awesome.The sound is exactly what I was looking for.I had the borla stingers on my 00 vette and this sounds so much meaner.Everyone at the dealership was impressed and I absolutely love them.They are very loud but at 70 on the highway I had no problem with hearing the radio or someone else talking.Im not flaming but I think in reality most vette owners are over 45 and thats why they think they are loud.The performance seems better to by at least 10hp imo which is just a bonus.This system is pretty much straight pipes so I would think it would give the best free flowing of all the systems out there.Angel said the install was so much easier than the corsas and others he put on.Can you tell I'm a happy customer!! I'll be taking the car to the tower shops sometime the next few weeks if anyone wants to hear them.

By the way,I have no intentions of adding an x pipe.I dont find the resonance to be that bad at all and there really is no gain in performance from the x pipe(2-5) max.The last thing I want is for it to be quieter.Im 31 years old.My 400 hp car now sounds like a 400hp car should.My car is a black 6spd coupe.If anyone wants to meet up in fort lauderdale just give me a shout and Id be happy to meet somewhere.

Bullet's
I installed the Bullet Quad and it is the best sounding exhaust I have heard. I have a 911 with the sport exhaust and a 350z with the Nismo exhaust and they done even compare with the B&B Bullet. About 2 month's later I installed the x-pipe and the car sound even better when its not at the dealer getting repaired.

I just installed them in my Black A4 and let me tell you - they sound great but they have serious resonance in the 1500 to 1800 range w/ some matched harmonics that make a few interior parts sing!
I do love the sound - it is uncomparable to any other C6 system but just know that w/ the automatic you will have some resonance issues.

I have the resonance there to ,but it went away a little after a few months.I used to have parts all over my car rattling at first.It was annoying,but things have settled now after having them on for 4 months.Thinking about an x pipe now.I want to hear a car with it first,I want to keep the sound very aggressive.With my mustangs and x pipe always made the car sound nasty and louder in a good way,but some people same the vette is actually a little quieter with an x pipe and others a different opinion.

"Resonance" per se', has less to do with the mounting of the exhaust assembly, than the muffler cans actual resonant frequency. All enclosed spaces have a resonant frequency at which they "oscillate" -that is, the sound combines and amplifies -. Ever "hum" in the shower, and find a tone that just gets REALLY LOUD? That's the "resonant frequency" of your shower enclosure.
Baffling and other means to move this frequency out of an audible range (or a range to which they would be less likely to be exposed to acoustical waves that would be in the resonant range of the space) is frequently used to reduce this issue. When the resonant frequency of the "cans" matches the resonant frequency of the cabin, they multiply off each other, causing the tooth rattling drone that folks can't stand.
The only portion of the exhaust system that's solidly mounted, is where the exhaust manifolds meet the engine - and the engine is rubber mounted. The spring hangers & rubber muffler hangers provide isolation from the frame/body, and allow the system to "flex" (otherwise it would crack the pipes if solidly mounted).

I installed the rubber bushings between the connection of the spring hanger and the exhaust mount/anchor. Instead of the spring hanger being directly connected to the exhaust mount (metal on metal), I added a rubber bushing between the two metal pieces. It now goes trans mount, spring hanger, spring hanger mount/anchor, rubber bushing, exhaust mount/anchor.
