i need a decat pipe for my r33 gtr? are these universal fitting or will i need one specifically for the exhaust system?

Think they are universal as the exhaust systems are made to bolt up to the standard cat

I have one for sale in my parts for sale thread.

Hi,
Some aftermarket decat pipes have temperature sender bosses and some do not.
I would get one with a temperature sender boss as fitted from new. Nissan had a reason for this feature but I expect there will be many people who will tell you it doesn't matter. They will not be engineers from Nissan though.
Regards.
