Fabspeed Bypass pipes DO ROCK.....got my car back after 2 weeks in bodyshop with the Gemballa stuff. THEY ARE LOUD....ALMOST like a rice-car. But....its not that obvious on the interior which is good for me. I'll post pics of my car soon

Did you take any pictures of the install process or plan on doing an install write up? I'm interested in the top bolts and the tip to remove them.

It really is so simple once you get the car up on the lift. You'll see and be able to reach all the necessary bolts

We just did this on Fred's TT today. Sounded awesome!

Sharky: will it be too loud combined with the Techart sport muffler?

There are always some trade offs for the benefit of the mod. Only you can decide if it is worth it. My vote, get them

I recently chipped my CT and asked the installer to put on the cat bypass tubes too. He refused. Said that he's had clients that have lost power with them and that the CT requires a certain amount of backpressure in order to deliver full power.... Hmmm.

Anyone try the high flow cats that some vendors offer as an alternative to the bypass?
