Have any of you consider to take the "dynamic damper" from OEM exhaust pipe and install them on your aftermarket pipes? Those parts suppose to absorb vibration from the pipes and mufflers.

see parts number 6 and 15

 

If those dampers were really needed companys like HKS, Stillen and F1 would have included them with their systems....don't ya think? Each of these companys spend hundreds of hours on design/sound of their systems, they're not needed....

Yes but same argument for Nissan/Infiniti they are there on the original for a reason too. Unless aftermarket part got some build-in or something special about their pipes that will remove the vibration.

 

If you think about it vibration can be eliminated by those rubber biscuit hangers we all love and use.... I have zero vibration in my exhaust system from HKS.

Stillen offers the brackets for you to just move them over.

 

Can you get these brackets separately? I'm of the opinion these things are there for a reason. I think there is less testing on aftermarket products than most people assume--they just use what has been done in the past.

 

Csquared is right, Stillen has built-in mounts for their catback. I've drive with and without those weights and it makes very little difference if any.

 

I have the Stillen and have had no issues at all. It does have some of those dampers built on to it - just not in the same place as the OEMs.

 

Ive had exhaust since the 2nd week of ownership and never had any vibration issues.

 

There was a forum on here talking about exhausts and how Stillens vibration is REALLY annoying to people who sit in the back seat. When they test exhausts, they don't have them for a year and work them in like regular people. We're pretty much market tools for them. While we express our feelings and ideas for free. They may be browsing sites and taking that information for their self gain and make thousands. That's they way free marketing works at least :P

 

Who cares, they're in the back seat! And it makes girls back there go wild , they don't want the drive to end

 

I don't know if it's the exhaust, or lowering the car, or going with 19" wheels, but there is definitely more low-level vibration now than when stock. I know our passenger seat is prone to vibrate, but I feel like it is doing it more now than when stock and I can feel vibration in the driver seat even at idle. I've gone under a gazillion times and am the exhaust isn't hitting anything. I know the rubber exhaust hangers isolate some vibation but they are pulled pretty taught and I'm sure some gets through. Why would Nissan put them on if they weren't effective? If anything, I would think the potential for aftermarket exhausts to vibrate more is greater.

 

OEM exhausts are covered with numerous heat shields. I'm betting its safe to assume that the parts in question are engineered more towards dampening heat shield noise rather than vibration.
