Finally got around to getting my first 1/4 mile time done. First time I ever did this, and my start was not all that great, also the slope was slightly uphill (.94%) Also this was in automatic. I couldn't get the Launch Control to enable not really sure what I'm doing wrong; so If I can solve these, I think I can get in the 11's.

took the ARM Catless downpipes off and replaced with AR Design Catted Downpipes with Magnaflow Hi-Flow Racing Cats. Pretty happy with them, they sounds as good as catless. The CE light that never came on with catless [odd, I know] came on, so I used extenders on the 2nd O2 sensor, and that solved it immediately, so now I'm back to being legal.
Also got my H&R Sport Springs installed, which lowers the car back to OEM height but slightly lower.

so....the AR Design downpipes with integrated Magnaflow HiFlo Cats kept giving me a P0175 Bank 2 System Rich code. Tried everything, including $400 on a set of brand new Bosch OEM O2 sensors. We figured it's because they moved the location of the downstream 02 sensor 5" out of position, which causes the sensor to send a "lean signal" to the fuel mix sensor, which tells the DME to add fuel when it should not be.
I went back to Catless Downpipes, and welded in some EPA compliant GSport Racing Converters to the mid-pipes to control the smell and smoke. The code went away when I did this.
Xtreme Powerhouse was really great about this and gave me a full refund on the downpipes.
