ok i did a search for "test pipe o2 sensor" and it listed a lot of extraneous thread that had nothing to do with my question

i was helping a friend install his megan resonated tp and noticed he had an o2 bung for his secondary. i'm looking for an unresonated tp (interested in helix) but one that has the o2 bung welded in. are there any manufacturers that sell tp's with o2 bungs welded in or will i have to take it to an exhaust shop to have it done myself?

thx

 

Search brotha..make some calls.

 

well most catbacks come with a bung already welded in but i havent really noticed many TP with one. worst case take it to a muffler shop and have them weld one in for you. probably about $30 or so.

 

+1^^^like he said or check out the ultimate racing test pipe.

 

i did...

well i noticed the cobb tp for the 8 has one welded in. i dont recall the hks carbon ti having a bung

thx for the input though

 

most exhausts for the VIII have the bung already.

Cobb for sure has them on their resonated tp's. Check megan as well.

most midas and meineke shops will weld a bung in, and as mentioned - it should be ~$30.

GL with it.

 

yea i have a muffler shop down here that'll do it no problem (muffler man)

ok yea nvm i went to the hks website and they didn't say anything about o2 sensors but i found a pic of the full exhaust in the marketplace and it does have one in the cat-back

thx man
