My xflow got better with age. Still loving it.

 

My smog is actually due in late May, but I took it in as soon as I received my notice (you have probably received yours by now) so I would have time to deal with any issues, like switching back to stock. I was very happy with the results and somewhat surprised by the readings:

Hydrocarbons (HC) PPM at idle:
Max - 100
Ave - 17
Meas- 28

Hydrocarbons (HC) PPM at 2500 RPM:
Max - 130
Ave - 12
Meas- 12

Carbon Monoxide (CO) % at idle:
Max - 1.00
Ave - 0.00
Meas- 0.18

Carbon Monoxide (CO) % at 2500 RPM:
Max - 1.00
Ave - 0.10
Meas- 0.19

For comparison, two years ago, with stock exhaust, all measurements were zero.

 

ASLAN,

Thanks for the feeback!

We have had several reports now, all with similar results to yours, some even at 1/2 the levels you are showing...From the data and feedback I have received, it's safe to say that our X-cellerator systems pass the emissions testing in CA. without any problem.
