Help! Vibrating Catback Exhaust
I had my Invidia Gemini installed last Tuesday and everything was fine until early this morning I got my ERZ hfc installed and the whole catback exhaust is now vibrating. Pressing the accelerator pedal and as soon as you let off the gas the whole exhaust system vibrates like hell. We checked all the bolts and everything is tight. Do you guys have any suggestion what the problem is? Please help.

It could be just the nature of the HFC. Rattles/Rasp are fairly common.

check the crossmember, alot of exhausts tend to sit very close to it and are probably vibrating against it, its a pretty noisy occurance.

when we lifted the car up to the lifter and rev it, as soon as the rpm drops down we saw that the catback is vibrating. It just happen when I installed the ERZ hfc. We checked if it is hitting against something but we didn't see nothing. My transmission is vibrating too.

Then I would say the vibration is really coming from the front but just getting amplified on the CBE. Double check the HFCs.

It only happens at exactly 1800 rpm. I put it up in the air and tried free-revving it to see what was vibrating, but everything seems solid. I've followed the entire exhaust system from the exhaust manifolds to the muffler and nothing is touching or loose from front to back. All exhaust hangers/bushings are in use and tight.[YOUTUBE] |

It will vibrate. I'm pretty sure what you are hearing is the exhaust touching the crossmember. Mine didn't touch either, but when running and vibrating some it would. I just put a thick washer on every bolt hole between the cross brace and the car and it solved the problem.
I have Gemini + Berk test pipes.

I don't know. I don't have any idea now. I love the sound. I love the noticeable power gains but with that vibration, I am not gonna' be satisfied
