Invidia Gemini - Anyone else having issues?

HOOPZ · 11-04-2010, 12:19 AM

Sorry to hear about your luck with it. I've got about 5k on mine so far and no problems yet, knock knock.

how does the invidia exhaust sound with hfc's? raspy?

I don't have hfc's, but i do have the gtm resonated test pipes and it sounds great. No rasp that ive noticed, but I've not heard it from the outside under normal driving conditions.

lately Ive been getting this violent rattle (for like 1 second) when downshifting at low RPMs. Usually happens after I drive the car hard for a few runs.

Anybody have this issue?

It's not shuttering like you're about to stall the car is it?

docaam · 11-07-2010, 02:29 AM

ok guys, I had a FI 18" SS exhaust which I just sold, I am looking for a quietier option then FI so anyone who heard both Invidia+HFC is less louder then FI CBE alone or not?

I am in between Berk CBE+ Berk HFC or Invida CBE + Berk HFC, only issue I dont need any drone like before and need the sound of be on minium under normal driving conditions

I have Invidia and ERZ HFC. Having compared side by side with someone else with just FI, mine was a little quieter...not by a lot. My combo has no drone. Compared to someone with FI plus HFC or TP, the FI combos were much louder. Bottom line, if you don't want loud, don't get HFC or TP. Having said that, Stillen and Invidia are probably two of the quieter exhausts around, and I'm happy with my setup.

Thanks for the info man, actually I am changing because only FI with 18" reson sound was fine slightly louder but ok for not getting into trouble with police here. But I want to add most probably HFC or double resonated TPs so with Invidia i guess the sound level would be same or slightly lower then FI along.

How is the sound on normal cruising under 3k rpms

djpathfinder · 11-07-2010, 11:01 AM

Unless you're gunning it the system sounds about the same as stock from the inside while cruising. No annoying drone on the highway. The tone is deeper than stock for sure. Watch this video for a good comparison:

just finished watching that thanks man

djpathfinder · 11-07-2010, 11:47 AM

Yeah, that's so weird...2 problems on the same exhaust. Maybe you're taking those turns too hard. LOL

kevr6 · 11-07-2010, 03:32 PM

Double checked mine yesterday! No issues!

esfourteen · 11-27-2010, 09:59 PM

They sent me a new pipe for the passenger side that had a crack inside the flex pipe, I installed it about 2 weeks ago and its ******* CRACKED AGAIN. The NEW pipe they just sent me is cracked in the same spot, inside the flex joint. WHAT THE FFU#RFD(8y03r8931r893r-9ujvugewohu

/endrant

strongly considering placing an order with berk...

They are sending me another pipe and they want my old one back to investigate, hopefully they can get this fixed permanently. My only guess is the particular type of flex joint they are using at the moment and this cold weather we have here. Theres no other reason for it to crack in less than 2 weeks from quite normal driving.

djpathfinder · 11-29-2010, 12:36 PM

hmmmm. Yet, the driver side is ok. Strange to get two on the same side with the same crack.

its also strange that this crack developed so quickly, perhaps the passenger side sees more flex for some reason.

BalanBro · 11-29-2010, 06:48 PM

How did you notice it was cracked? I imagine that you wouldn't be able to see it without removing the exhaust.
