Actually it is coming from the rear section. Its resonance is so drastic that it is vibrating all of the plastics in the boot. I have a feeling it is the cans. I think GReddy put those resonators there for a reason.

My thoughts - very doubtful. The way GReddy designed this exhaust is what is causing the issue. Again, those resonators are there for a reason.

I was foolish to remove them for the extra gain.

If you are talking about the GTM 3" it is mellow compared to the GReddy exhaust.

Thanks for all of the information on resonance. I don't think I can delete any of the length of this GReddy piping, so I will try the resonators they place in the cans at the end and see if that helps. If not, then I think I will just try to stick two bananas in the tailpipes.

The EVC's fit is just as good as it looks in those photos. The only caveat is that the angle is a bit harsh for the driver and it takes some maneuvering to read. That and at night, the light from it is in the passenger's eyes. *haha* Who really cares about that, though?

I didn't want open dumps, so no externals. I didn't want to recirc them, either. For the power level that I wanted, internals were perfectly fine. Any possible boost creep/spikes is going to be mediated by the EVC. But, I haven't seen any yet. Even with the more free-flowing exhaust.

How much boost are you running? I think at low boost levels internal wastegates work great.

Loved reading this thread over and over I can't find that video that shows the car running in the streets and fly by

7psi mostly. I have a "high-boost" setting of basically 9psi. But, I have yet to even run it at this level.

by far the best TT install ever, looks amazing on the nismo. Question, are your boost gauge and wideband in a 2 gauge pillar or did you just install them in the stock piller?

They are installed in little cups mounted to the stock pillar. They are actually ingenious little things that Sam came up with. Very little room taken up and no need to move your head when going around sharp left-hand turns. Completely unobtrusive. I love them.

Update on the GReddy TI-C TT exhaust. After putting the resonators back into the cans, all is right with the world. These are absolutely there for a reason. Drone is acceptable at cruise and cabin noise now consists more of tire and typical road noise. Best of all, I'm no longer vibrating the rear deck apart from 2500-3000 RPMs.

Are these the silencers or something else?
