Are emissions a problem with the test pipes? Did you ever encounter the CEL problem? Looking at getting the JHM tune and pipes. Already have AWE track.

Im wondering about the CEL as well. I want these but cant be throwing a CEL or able to code out the O2 sensors(supposedly Mass will fail you for it)

Tune, test pipes, Supercharger, full exhaust, BBK etc.. the other question is classified information :).

Honestly, I didn't ask them why or how come I don't get a CEL. I did it for HP and the mod delivered.

I'm thinking about getting the JHM tune but I had read about problems on the V8's and the CEL. Wasn't sure if they had worked it out as being a ECM/Tune issue. I also like the idea of the test pipes but wanted to know how that worked with emissions. Are they moved O2 spacers? Or coded out? Did you install yourself or have a shop do it? Was it a JHM installer? Did they have any issues with the testpipes?

I've thought about going the way of the highflow cats to bypass all this but don't see those listed anymore.

I know previous generations of the test pipe were guaranteed cel free but they don't have that on the s5's. also early gen tunes had issues I thought the newer tunes weren't an issue any more.

I have the tune with the catless test pipes. I think if u go catted u might not get a cel. Maybe will though. Call jhm and ask. I passed inspection with the catless and tune at a local shop lol. No hook up just went and was all good to go

Trust me theres a way to get around the inspection. If a cel is what ur worrying about the tune takes it away. If they check to see if u removed the cats then u gotta find a "guy". Gotta pay to play if thats the case
