Am having just a little trouble fitting the INVIDIA Exhaust.

I need some info for the following.

I have unscrewed the three nuts just right after the catalyst in which the OEM exhaust is attached. However the bolts are still attached on the catalyst. Are this welded or something or they are one piece with the catalyst; cause I cant remove them, plus they have a strange shape that dont allow me to unscrew them.

If they are in one piece with the catalyst, am wondering if the nuts of the Invidia will bolt on the OEM bolts of the catalyst!

My S2000 now sits in the garage and am at work now, so any fast replies will be much appreciated in order to continue the instalation of the Invidia.

Edit: Yes those bolts are pressed into the cat and your exhaust will connect up to them.

Maybe this will help...

Thanks, I have already gone through that.

If the bolts are pressed that means I cannot remove them? I think there is a slight difference between the European and USA Version on the Exhaust bolts/catalyst.

I just hope the Invidia nuts will bolt on properly. And as far as I have understand the bolts & nuts tha are included with the Invidia is for the case that I want to install a test pipe, right?

my mechanic had to use a air impact to punch it out of there...

The nuts on my exhaust were actually rusted to the bolts and when I unscrewed them they ate the threads and the sheared off two of the bolts.

I just used a hammer to smash the old bolts out of the cat's flange. They are just pressed in so a bit of elbow grease helps. Also, this process is easier if the cat is unbolted from the car.

Am glad that am getting some really useful info.

In two hours I will be going home to continue the instalation. Cant wait to feel and listen the Invidia.

one of my bolts actually stripped and started spinning so i had to use a wrench to keep it from spinning when I removed factory exhaust and put on my A/M. the nuts were also rusted on there so I used a little bit of ATF and they came right off..

those cat bolts ARE NOT FIXED - you can punch them out with a hammer

The instalation is finally completed. I just used the same bolts with new nuts. Here are some photos! Thanks again guys for your replies.









More photos during the installation is here. The description is in Greek but I will write down the English version too.
