So i bought the Injen track exhaust and have test pipes and this thing is LOUD in the cabin that it makes the plastic vibrate. Is there any way to find which plastic pieces are vibration and fix the vibration? It's driving me nuts and preventing me from enjoying the bliss of this sexy set up lol

 

Sry i think this should go in the exterior/interior section..... I put it in exhaust section cuz it was the exhaust causing the rattle but exterior/interior seems more appropriate

 

Can you locate the rattle/vibration?

 

Find what's making the noise, then throw some dynamat in there.

 

Same kind of thing happened to me...turns out it was the interior pieces attached to the hatch, along with a plastic piece that covers the hatch brake light.

 

Seems like that's where my vibration's coming from.. How did you fix it?

 

I removed the pieces lol, but now I have another noise that is like a squeaking sound whenever I hit a bump in the road, I hear that in the trunk as well, need to look into that tonight.

 

Is it the piece with the "Z" imprint in the back? The rear strut bar?

You should try sticking like towel or something in between the plastic pieces, maybe that'll help the problem

 

No, if you open the trunk, look on the inside of the lid and you will see grey trim all around the window. There are four pieces that make up this trim, plus a 5 piece that covers the brake light.

 

Replace your test pipes with OEM Cats and a ton of that vibration will go away.
