Make sure you wear a proper breathing mask when doing it. Some really nasty chemicals sitting in cat's. You'll need to remove the drivers side driveshaft to get it out. It won't pop like a TAPE ecu but it may pop every now and again.
You really want to cut it open with a grinder, then get it welded shut again.

The above is literally taking the car to about 3,000 RPM's then letting off the throttle (overrun). That's what a TAPE ECU does. :thumbs:
None of the other ECU's do that, it's basically like the Golf R's with DSG etc, it dumps a bit of unburnt fuel into the exhaust and causes it to pop. Obviously it makes your car less economical, you can stop it from popping, which I do near police. :wink:
