Bought a 07 tt this summer and it sure don't sound like it has 500hp.
I find the turbo spool sound of the bypass or decat systems. But at the same time I dd the car so at 6am I'd rather not wake up the neighbours. Which has led me to consider innotech and frequency intelligent. I don't want to tune the car, do O2 simulators work on are cars? My other option was awe catted system just dont think I'll have the wail I'm looking while under high boost.
advice much appreciated. Live in Canada so emissions not a concern

If you are referring to the O2 bung extensions, they do work in most cases. There are some good ones and some really cheap ones..Usually may not need any with a tune..only needed when you change/remove Cat and leave ECU stock. You just need two for the POST CAT O2 sensors.

Here is a link to some of the good ones: LINK HERE

Hope that helps...And other may have additional comments?
