I just bought mine, and had a question. Since the o2 sense connects to the stock pipes, when I put in my test pipes, what do I do with the O2 sensors? Is there an area to put them?

Sorry, not very familiar with test pipes, and the senors.. if I'm completely wrong about something, someone please englighten me

 

There should be a bung welded into the side of the pipe that the factory O2 sensor threads into.

 

Oh okay, thanks! So just simple unscrew from stock CAT's, then install these test pipes, and screw them back in?

Is there any precautions I should take while doing this?

 

Do not drop them.

 

buy 8 screws and nuts for more easy install (replace the stocks ones!) size: 14mm 4" long!

P.S you can use the stock ones but you have to take out of the cats!

 

Avoid getting them dirty when you screw them in the bunghole

 

Dude, that's so wrong!

 

where'd that come from

 

what do you mean?????

 

"bunghole".........NICE! thats the funniest thing i have heard all day!

 

As Beavis once said..


I NEED TIPI FOR MY BUNGHOLE!

 

replace the stock ones that are attach on the cats... to make installetion more easy!

 

oh, OK

so they are 4" long and 14mm in diameter??

do I need washers??

 

I did. double them up too!

 

YES!

 

Those sizes are ridiculous! Bigger than the bolts holding my house to it's foundation!

I'd think something like a 3/8" x 1 1/4".....but I'm guessing.

 

The ones we supply are 3/8 fine thread I believe they are about 1.5" long

 

You can use that size too... I was mixing the american size w the european size...sorry!
