Recently I've been getting a weird metal rattling sound at around 3k rpm, the exhaust seems fine and everything seems solid, but I figured since I've had the exhaust for nearly 2 years (maybe longer can't remember) it's probably about time to change all the gaskets.

I've tried to search Invidia's website but I can't seem to access it, I wanted to know does anyone sell a replacement gasket kit for the Invidia Gemini?

or does anyone know where I can buy some good quality exhausts from other suppliers? I'm guessing any 60mm dia gaskets would do correct?

 

Actually does anyone know what the OEM exhaust diameter is?

 

Oem diameter is 2.5" I believe

 

2.5" = 63.5mm.....can we consider that the oem gaskets should be ok on my exhaust?

 

Bump* any advice?

 

Double Bump....

Can anyone shed some light if I can simply replace my Invidia gaskets with the OEM gaskets?

Invidia Dia = 60mm
OEM Dia = 63.5mm

 

Which gaskets u need exactly ?! FYI .. No OEM gaskets are installed between the cats/headers manifolds ( those with 3bolts i mean ). as for the catback .. yes the factory do use them in between ( those with 2 bolts ). if u're referring to the catback gaskets then you can use a tube of a High Temp Red RTV silicone without gaskets with no issues or what so ever.

 

Yes the main gaskets I want to change are for the cat-back system, I would prefer to use gaskets instead of the High Temp Red RTV Silicone, because that would involve having to dismantle the exhaust and I don't have any places to do that.

With gaskets I'd be able to easily take out the old ones and replace them with the new ones.

The question is can I use the OEM gaskets on my Invidia Exhaust?

 

^ yes you can use them. flanges are always identical to OEM spec no matter what size your after market pipes are.

 

^^^ wrong... one of my gaskets fried itself to **** and when i went to autozone, pepboys etc.. they did not carry the right size gasket. the oem gasket is slightly bigger. ive been looking around as well and havent been able to find anything. hence how i came up on this old *** thread lol
