does your testpipes make a hissing noise when you let go of gas? just installed the pipes on sat and noticed a hissing nosie when i let go of the gas. i pretty sure the bolts and everything is on tight and its not my exhuast. my friend says its normal but dont really trust him..

oh and does anyone know a way to fix the o2 sensor. i got the non-fouler but after installing it, its so close to the ground. affaired its going to break when i go over something..

 

What brand test pipes?

 

Almost all I have sold/installed/heard hiss

 

dont know.. a friend got it for me. wish i knew

 

Yeah, the hissing is normal.

 

yea. searched hissing.. now just wish the 02 wasnt go low. but i guess you cant have everything..

 

English? That first post made me think this was a third grader. Sorry and no there is nothing you can do to make the o2 sensors any higher.

 

-Yes hissing is normal.

-You can get a welder to relocate your 02 bungs. Thats what I did with my Helix v2's.

 

Yep. I have Kinetix resonated tp's. No exhaust leaks, and they do hiss a little on decell...

 

yup all normal!

 

The oxygen sensor should be level or point up. Definitely not down. Poor test pipe design.

If it's pointing down, it'll have a tendence to collect condensation and will fail prematurely.
