Agency Power Valvetronic cat-back

Once again, iPhone quality but this is a pretty good rendition of true engine/exhaust noise with the system.

Weather permitting, I will be taking out the goPro cam tomorrow...

Thanks for sharing! It would be great if someone would make a tutorial on how to get Race Start to work as well!

CELLryuu

oh, nice.

how much traction control do you feel was being used from 0-30?

You can see power being cut during the first few seconds of the launch.

If the power is cut what is the point of Race Start

Sounds great, was that with valves open or closed?

The purpose of RS is to allow you to start from a stop at a higher rpm in an auto clutch (dual or multi) tranny car which mimics what can be achieve in manuals. Thus allowing faster acceleration times.

Just like my Trans Brake on my Z..

Valves open...

Only time I run them closed is if 5-0 is nearby...or if I feel like respecting my neighbhors

I'm sorry, not understanding the question..

If you're asking if I could feel the car doing it's thing to minimize wheel slip, I would say that it did so until about 25-30 mph as you indicated.

Otherwise, not sure how to answer...

Step 0: Turn ESP to sport mode
Step 1: push the brake pedal pretty close to the floor
Step 2: turn the transmission setting button to RS
Step 3: Pull right paddle shift lever
Step 4: Push throttle pedal ALL the way to the floor within 2 seconds of receiving "racestart available message"
Step 5: Release brake pedal within 7 seconds of having the gas pedal depressed and engine pinging off of 4,000 RPM..

Step 6: enjoy, rinse and repeat!

Getting optimal traction off the line - sometimes the quickest way to get things done is the least aggressive!
