Invidia Gemini CBE & ERZ HFC Review (with db comparison)

djpathfinder · 06-10-2010, 09:10 PM

Does it vibrate all the time or intermittently? I had a vibration that was constant no matter the RPM...if you read my earlier posts from a couple of weeks ago, you'll see I found my rattle was caused by loose O2 caps. Make sure those are tightened. Do you have the stock exhaust? If so, make sure the heat shielding isn't loose or coming in contact with anything else. If the connections (flanges) are seated properly, bolts tightened and there's no exhaust leak, then they should be fine. Is any part of your exhaust contacting other parts of the car (e.g. sway bar)? Just a few ideas...hope it's an easy find and fix.

it is not constant. as soon as the rpm drops down that's the time it vibrates. the whole catback system is shaking like crazy. I have Invidia Gemini installed last week and I don't have this problem at all.

you should still make sure the (2)02 cap is tighten enough because I only hand tight them before I ship it , also the cel fix bung is two piece make sure the second piece is tight also because I also hand tight that only before I ship them.

only these two piece can move and screw on.

if after this don't work you might want to consider stronger exhaust hangers.

I am going back tomorrow to the shop to check everything out again one more time. the "cel fix bung" the o2 sensor won't fit on that extender that's why I didn't use it.
