Explain. The harmonic balancer isn't changing here and the accessories aren't changing so I don't understand your logic.All of this sounds fun until the vibration cracks something *really* expensive ;)
There are dampers on the headers as well. Unless the exhaust companies know the critical frequencies to properly place the dampers, any changing of the headers will degrade durability.Explain.

They're on the cat pipes, not the headers.There are dampers on the headers as well. Unless the exhaust companies know the critical frequencies to properly place the dampers, any changing of the headers will degrade durability.
Before the flexpipe, not after. So it will act as a dampener for the engine itself through the headers. Everything prior to that point is hard mounted.They're on the cat pipes, not the headers.
Adding and or removing a fixed mass to/from the exhaust system will not effect vibration. It is there for other reasons.Before the flexpipe, not after. So it will act as a dampener for the engine itself through the headers. Everything prior to that point is hard mounted.
No. In a vehicle primed for weight reduction (carbon fiber composite front end, rear seat delete, complete aluminum reworking of front suspension, etc), they won't leave a random weight. It's a mass damper. During DV work they literally sat in a chassis dyno running the vehicle with accelerometers and slowly adding mass until they met their metric.Adding and or removing a fixed mass to/from the exhaust system will not effect vibration.

I have had headers and OR X-Pipe on my car since I bought it. Zero changes in vibration.No. In a vehicle primed for weight reduction (carbon fiber composite front end, rear seat delete, complete aluminum reworking of front suspension, etc), they won't leave a random weight.

I have nothing to gain arguing this point. I am an engineer in Southeast Michigan. Please listen.
The vibrations this damper was designed to help with aren't with regards to making the engine sound better, rather it is to help with durability.I have had headers and OR X-Pipe on my car since I bought it. Zero changes in vibration.
That thing looks like it's attached to the factory exhaust, which I removedThe vibrations this damper was designed to help with aren't with regards to making the engine sound better, rather it is to help with durability.
Perhaps customer street vehicles won't have a problem. I just know that in the engine DV (which is MUCH more extreme than whatever a customer will do to their vehicle) needed many NVH counter-measures to pass, this being one of them.
How do u like the LT’s? Worth it? Insanely loud? Are you still able to quiet it down to non hoon levels with valves closed?I'll chime in here. I just did Kooks LT's on my 350...
