hey this is a little off topic but since we are talking about cats and test pipes, is Gruppe-S/Helix going to offer a Hi-Flow cat any time soon?

Thanks
Ryan

 

Yes they are....Helix will be coming out with a high-flow cat, probably in a month or so...

 

So, any suggestions on the "SES" light fix Gruppe-S?

 

well just had the helix dp and test pipe installed. what can i sy it pulls like a champ. no cel on either. much props to helix for a fine product. also very nice and clean tig welds

 

this friday my helix catback will be installed. will i lose alot of low end power?

 

just reporting i have gone 200 miles with no CEL or SES light thanks Gruppe

 

Hello, Did the SES light came on after you install the test pipe? if so, Can you please re-verify the spliced wires? chances are, you probably x-cross the black wires. Just to clarify the o2 sensor wires, there are 2 black wires. one wires is for the ground, and other one goes back to ECU. If you cut both wires at the same time during initial installation, you will probably ended up switch the black wires during splicing. It is advised to splice each wire at the same time to ensure proper installation.

Thanks!

No, you will not lose any power down low. complete turbo-back will help the turbo spool up faster and yield more HP!

Thanks! Glad everything is working great for you and your ride!

 

quite honestly, you don't need to re-splice it. You can actually re-route the o2 sensor wires. Here is how to:

This weekend I will definetly switch the two black wires and see what happens. The only thing I am curious about is that initially it took about 25 miles or so for the light to come on. If I did have the two mixed, shouldn't the light have come on immediately?

 

sometimes it takes a few miles, how many times did you start and shut down the car withing that 25 minutes, I know that it in some instances it takes a preset amount of "drive cycles" for a code to be thrown.

 

I only started and shut down the car twice within the 25 MILES. I'll switch them tomorrow an see what happens.

 

sorry, was tired when I missread that

 

no problem.

 

Bump!
