QR25 Header and passing emissions (Joshua Gary)

Hi Joshua
I did the exhaust on my SpecV last year.
I bought a Stillen header, and had a local exhaust shop do the work for me.
I got a catalytic converter from Random Technology.
It was installed at the location of the original second cat.
I had the second sensor relocated behind the cat.
I have had no issues with Check Engine lights, or anything else.
The unit I bought has 2.5" inlet and outlet size.
I then took my car in for testing and passed with no problems.
I bought my cat directly from Random. I dealt with Dave at Random and he
was very helpful.
Cost on the unit was $275.
