Just wondering how do you tell if the test pipe is backwards... i had it two ways.. and i can't tell a difference.... one way the 02 bung was facing the back side of the car.. i just got a wideband and needed the 02 closer to the downpipe... so i turned it around... drove it both ways can't tell a difference in power... sounds different though...

Thanks

 

does it really matter?,,, it is just a holo pipe,,, move the bung close to the end and call it a day

 

just wondering.. not sure if it matters because some test pipes have... arrows stating which way it goes...

 

how much did you pay for the pipe?

 

pmed^

 

to tell you the truth..megan...has a good price...but...you'll end up buying another one soon...b/c they seems to crack....good luck...with it...

 

It does not matter even if it had a arrow on it it is just a pipe does not matter at all

 

only ones that really matter have resonators in them, i would keep the bung close to the downpipe facing passenger side, like stock.
