Ditto. I am running that Invidia N1 right now with a 70mm testpipe and it is tooooo loud and drones bad. Will be switching to the HKS single 75mm and installing a PLM header.

 

ditch that high flow cat and just get a test pipe. and even with a test pipe the drone will still be incredible lol

 

Vibrant makes a weld in resonator some people have used to quite down Invidia exhausts.

I had one welded into my InlinePro 3 inch and it made a huge difference.

 

so does the vibrant resonator make the invidia like quite??? i tried watching your vids it wouldent let me

 

ohh and was doing some more research and it seems that a header on the s2000 dont make much difference in the sound/toneof the car and performance ...honestly i dont see my self spending 500 or more for a "5-10" hp increase

 

I can't say what it would do for an Invidia. For my 3" single it eliminated most of the droning at cruising/highway speeds and quieted the overall volume noticably. It's by no means quiet now, but I can hear my stereo and talk to a passenger without any issues.
