i have the full magnaflow exhaust system ,larger intercooler, K&N filter system, complete ic piping, aeroforce interceptor gage.

I want to install a CATLESS DP will i have codes issues all the time
can my gage remove the code or cancel it out, will computer kept record of all the times codes were sent
will the DP void warranty, i can reinstall old one if taken to dealer
I like the sound of my magnaflow now, will it be louder after installing the DP

Yes it would set a cat code all the time. I think that summit racing sells a wigit that plugs in the down stream 02 sensor and fools the computer to think there is a cat there. Im sure you already know that it wouldn't be steet legal.

Happen to have a link to said Wigit? I'm interested..

really??? the hahn system doesn't throw a code. i thought they were based off one another?? mine has never thrown a code.

It will for sure throw a code its just a matter of time. The interceptor can clear it but it will come back. Get tuned and disable that code from popping up and youre good. Youre in Cali so i dont know how strict they are over there. Also get rid of the K&N

Does anyone sell a downpipe with a high-flow cat?

All the major players do (i.e. Hahn, ZZP Dejon, etc). Just pick your poison (favy brand) and buy one.

Alex, and MightyMouse are correct. HAHN has their o2 bung in the right spot and angle, NO CODES. funny too, cuz for all the crabbing about HAHN. I've never thrown codes with their products either

The people who made O2 sims were shut down by the EPA a few years back so I'd guess they are harder to find than they used to be. I designed one once and I can tell you how to make one if that's something you want to do. The one I did fit on a 1/2" square PCB so it doesn't take much. I used a 6 pin PIC10F200 but I believe Casper used a 555. A 1 cycle per second square wave cycling between about .25V and .75V should be enough to make the ECM happy.

If you actually want to build one, I'll hook one of my EFILive cables up to mine and scan the rear O2 voltages to see the range.
