Finally got a chance to install the noisemaker eliminator pipe from PPE,high quality item and custom made for your car,ordered some 500 deg low gloss black paint and primer and will paint her up when i get a chance.
Honestly I didn't... But I had done downpipes first which did change the sound and then did the entire set of hotpipes. It looks so much better under the hood though! ... Especially in ceramic coating.

The IC to TB pipe black ceramic coated..aka noisemaker eliminator pipe...
It actually does nothing for performance or sound,personaly would not try to plug that 1.5 in hole because of the amount of boost pressure,especially if your tuned,thats why the factory noise maker has a support arm connected to a hose for support,so it does not blow off. Z
