Dude let me know how that works out...I've had my eye on the cat pipe myself for a while...I wonder if the car will get louder if you are using the borla headers...Hey Greg you are running with a straight pipe only right?ampsarus said:I dunno, but they have a 4WD dyno- There is a Dyno GB this Saturday at Easystreet. I'm gonna do a pull for the hell of it.
Frank- I got the Random Tech cat pipe and custom 2.25" cat back to the N1. Also have Digital Fuel pressure, A/F, and EGT gauges commin- accurate to 1 psi, .001 volt, and 1 degree respectively.
The gauge works on the bench but not in the car. The IC in the gauge wants to see a change in voltage but my understanding is the front O2 sensor in our cars varies current with a steady state voltage. Besides, my gauge would only have a 20 point (.25 Volt)resolution. I could use mine on a dedicated 0-1 volt sensor or the rear sensor, but this is better...The gauge I bought has a 1000 point (.001 Volt) resolution using a dedicated O2 sensor in the header collector.FRAKK's2.5 said:Hey Andy did you ever get that gauge that you made working?
It just reads the O2 sensor voltage, you have to convert it in your head to the AFR. $75 w/o the sensor from www.speedshop.orgLo0mis said:Damn thats a sweet gauge, how much did it set you back with the sensor? And where did you pick it up? Does it just tell you sensor voltage, or does it give you the AFR?

Update on ESX is fucking don't even let them touch your car EVER. I didn't but don't.ampsarus said:There's Easystreet in Burbank....4WD dyno there, but don't know about the staff.
Though they did build a 10.? sec. @ 135 MPH WRX there....
