Hi,

I have both a 98 GS-R and a 01' Type R. On my GS-R I have a comptech header and an Apexi WS2. I want to put those on my Type R. I would put the the GS-R stock cat over on the Type R. I noticed that the Type R has an o2 sensor bung on the stock header while the GS-R does not(since the cat has two o2 bungs while the type R has only one on the cat). Will this throw a cel?

 

as long as both O2s are still in, it would be fine.

if you swap the complete exhaust from front to back, yes it will fit.

 

2nd post on swapping parts? your not very knowledgable of your cars man lol

 

Sorry, I'm not that aware of the differences between a type r and gs-r besides the obvious. I was just unsure about the location of the o2 sensor bung and whether or not it would throw a cel. I'm aware of the length differences. Don't worry, I do search though!
