first, this may be a stupid question, but is there an sp or only an sp2? if there are both, what are the differences?

second, what exactly are the fitment issues. i have read that an o2 bung needs to be plugged up, but also that an o2 bung needs to be welded on. which one is it? there is that s-shaped part after the cat that holds the o2. would this part need to be taken off for the install, or would it be left there?

that is a picture of the exhaust. fitment issues on that?

 

sp and sp2 are the same, with the exception that the sp2 is all stainless steel, and the sp isnt. Also there are no issues putting in a sp2 into a 97-99 ...

 

my sp "b" pipe looks nothing like that... It has two resonators, and it's ceramic coated..

 

so the one in the pic is the ss sp2?

 

nope......

 

so what is the one in the pic? just the sp? or is it something else?

 

the muffler section is an SP1, the b pipe.. I have no clue.. looks to be part of the orginal SP1 and something else..

 

just had my sp2 95-96 installed on my 99 maxima, and it was a direct fit, the guy just closed of the o2 sensor hole on the b-pipe and it fit fine with the exception of it being a little short but im gonna try to scoot it up a little tomorrow morning.

 

there are more pics available here if anyone knows what it is
