there is nothing we have to do to clear the CEL light. Nothing to splice? It all does its job by itself?

Hey Yellow,

I saw the prototype for this pipe in person. There is this little "Sheild", for lack of a better term on on side of the O2 sensor on the inside of the pipe. They played with a few different pieces before they came up one that did not set off the CEL code. It does not get in the way of exhaust flow anymore than the sensor itself does.

Cal, correct me if I'm wrong!

 

RonV nailed it right on the money! just for that he's getting one from me!

 

Mechanical CEL fix? How nice! What would you suggest for a downpipe to match and for how much $?

 

a new shiney Helix DP would go nice with that new shiney Helix Test Pipe.

Cal, you guys finally finished it. it looks bling bling bro!

Didn't Helix make a "2nd" version of their downpipe for the EVO for better fitment?

 

yup https://www.evolutionm.net/forums/sh...ad.php?t=82151

 

Hey Cal,

This is exactly what I've been waiting for. Any chance of a group buy? I'm in.

Bump!

 

If you say the CEL fix is MECHANICAL why did I get instructions with my Helix delete pipe saying I need to "cut and splice." Then I realized I did not get anything with the pipe to splice. Could someone explain exactly how the CEL fix works. Thanks!

 

Hey were you the one who came by late in the afternoon??? I think the mechanic forgot to give you the wire extensions to splice the o2 sensor wires.

Please give me a call!

Thanks

Gruppe-S......Is there anyway you guys could sell one of these with the bung included for the catback???? I'm on a remote island over here in the military and we don't exactly have a hardware store or stores to just go and pick one up....I'm an electrician so the wiring part isn't hard for me I just need the stupid plug for the o2 sensor on the catback....please let me know, I'll pay the extra couple bucks for the bung....
