happy thanksgiving guys!

i have a couple of days off and i was going to install my omnipower test pipe today. i have everything i need. however, the more i thought about it, the more i wondered:

do the slipjoints on the adjustable test pipe need welding? im sure it wouldnt hurt to have this done, i just dont really know anyone that can weld. and my local muffler shop is pretty schwaz.

thanks.

 

Yes, they will need welding.

You'll need to tack weld them in place while you get the fit just right, than fully weld them shut.

This is why majority of "no tools required, no welding" exhaust kits are bullshit.

Nice piece

 

i 2nd that. i had one and didnt weld it, on the 2nd day, it slipped off.

 

thank you!

i wish they would have said something, i wouldn't have waited till the holiday.

 

From my experience. The 02 bung didnt line up in the same place as OEM either.

 

Mine isnt welded and i have had no issues. It has been on my car for over a year. No exhaust leaks or anything.

 

If you dont have a Welder, Just spot weld it like said above, and take it to a welding shop, Cheap and easy

 

I dont see why you would have to weld it. Once its bolted up, its not going anywhere.

it does not line up, the O2 on the stock cat is in the back, the OMNI is in the front.
i hope its going to be a simple matter of extending wires.

how about exhaust clamps, ghetto, but might work.

what if you rotated the flange 180 degrees, and held the wires out with something? clearance issues im sure, but ill try and see.

 

I need to get mine welded... It leaks like hell, every time I let off the gas, it backfires out of the openings.

That don't sound too good. It turned out after I realized about the bung, I never even bolted mine up and found a SMSP cat instead.

 

I have this on my 94 si and i had mine hand tig weld'd and its the @!#$.

 

i don't have mine welded and I have zero issues. I'm also NOT running a 2nd O2 sensor.

are you throwing a code with that? cause that would sure make things easy.

 

Just think of it like this: When you connect two pieces of speaker wire together and twist the ends, a connection is made, and it will continue the current from one wire to the other. However, if you twist those same wires, and then solder them together, the connection will be more concrete, more durable, and will last longer.

To think that if you leave the slip joints as is, and not weld the joints together, that you would have a sealed exhaust, is just incorrect. The entire exhaust track moves and flexes while you drive. Those slip joints will also move and under extreme exhaust pressure in the pipes, air will find its way out of those joints.

Welding is very cheap. No point on cutting corners on something so minuscule. Just go get the thing welded.

 

I bought one over a year ago, and haven't put it on for this very reason. The dollar is doing so crappy against the Euro it would cost me more to get it welded than I paid for the test pipe.

 

i have this test pipe.. not welded, works mint

what sucks is, i just got rid of all my codes.

oh well, just when you get used to the pretty gauges

You may think it does, but it doesn't. It can work better. Weld it shut. Seal the friggin exhaust track. Running this test pipe without the slip joints welded is like having an exhaust leak. You loose pressure and disturb the flow of air through the piping.

 

okk might do it anyway i never knew just thought thats how they are..

It's all good bro. Exhaust kits and test pipes like this have slip joints for the sole purpose of being able to custom fit the length, but they should always be welded shut.
