second O2 sensor and Tsudo N1

[mitsuchev]

I just got my first DSM labor day!

I was wondering about the people who have the Tsudo N1 cat-back.
Since i have a '98 RS, i have OBDII and two O2 sensors, so do i need to modify the exhuast to accomadate for the second O2?

I tried to research everything on this exhaust i could but to no avail.
thanks for the info.

I do have a Tsudo N1 cat-back for my 2G GST.

I'm not sure about NT version of TSUDO N1, but mine comes with 2nd O2sensor bung.

I didn't have to do any modification.

Comes with everything you need....Hanger, gasket, bolts & nuts.

I love that cat-back.

If the exhaust does not come with a second o2 sensor bung there is a simple mod that can be done.
Find it at www.vfaq.com under the Exhaust section at the top of the page.

thanks both of you for the info, if i ever get a test pipe i will take out the second o2,
but if anyone has a OBDII n/t, that would be really helpful, just to reassure me.

i am going to get the exhuast as soon as my debit card comes in the mail, but like i said, it would be good reassurance. thanks for the posts so far.

Your new system "should" come with the 2nd bung like mentioned above. Any good company would know this and include it in the system. If not, you can either do the mod mentioned aboved, or you can follow this tech article and weld in another bung. I know it says for wideband, but it makes no difference and could be used for the 2nd 02 sensor.
