I'm pretty new to bolt-on parts and any additional aftermarket parts. I did a quick search but couldn't find the answer I was looking for. I just purchased a used Invida 60mm Test-Pipe. Currently my exhaust system is ALL stock, obviously I'm going to swap my Cat for the Test-Pipe. I'm under the impression that I should use new gaskets when installing the Test-Pipe. My questions are:

-What gaskets should I use when installing the Test-Pipe? Would OEM be fine, or should I use a different recommend brand if there are any?

-What should I use to clean the inside of the Test-Pipe? (There is some carbon in the pipe of course and around the inside where the O2 sensor goes.)



Thanks and I appreciate the response

 

OEM gaskets are fine or go to autozone or advance and get generic that are the same size and shape. Carbon can be wiped of with some simple green.

 

Sweet

Btw, reusing the bolts on the stock exhaust shouldn't be any problem right?


Also I SHOULDN'T reuse my current gaskets correct? I should purchase new ones right?



Thanks

 

Meh, you can use your current gaskets. If you hear an exhaust leak at that flange, then it might be necessary to buy new ones.

One side of the catalytic converter has studs, and therefore you can't reuse that hardware on your test pipe. The other side (connects to header) uses the spring bolts. You can reuse those. So you will need to go to a hardware store and buy three bolts/nuts that work.

No need to clean the inside of the test pipe. Wipe the flanges clean and install.

 

Ahh alright,

As far as the Bolts are you referring to before the cat or after?

Thanks

 

Well, technically you won't have a cat any more, but I'll play along...

Reuse the spring bolts before the cat. Buy three new bolts/nuts for after the cat.

 

hahaha,

Thanks. Just wanted to get all the parts, so when I get the S back from the shop I can install the pipe and my new soft-top

Super excited.

 

you can just reuse every bolt. i didnt have a gasket and didnt want to fork over 14 bucks so i bolted it up with no gasket. i want it for more sound than to go fast. if i have a small exhaust leak... meh dont matter to me lol

 

^^ u gonna be choking from carbon monoxide soon enough...!!

 

I'm pretty sure that the connection on the back end of the cat is three studs with bolts, and you can't remove the studs from the cat. Perhaps I am wrong?
