GT Black series exhaust
Curious opinions on what you went with, and how difficult install was.
Not looking to change tune or anything else but exhaust.
Thanks in advance!

Looking for any recommendations (such as catless downpipes if suggested by someone who has done them), and trying to get an idea what is required to install.
Option 1: CUT existing pipes and install - in their shop they charge approx 3 hrs labor. Of course downside is can't ever 'cleanly' return to OEM.
Option 2: MUCH more complicated install - in their shop they charge approx 30 hrs labor - have to move a lot of things around (lift engine, drop transaxle....)
Much cleaner install as nothing cut, and thus could return to OEM one day if wished, but clearly much more complicated, and I assume some risk involved?

These pictures should give you a better sense of why its so compliated and time consuming;

Much easier install, but theoretically difficult to return one's car to stock (if ever wanted), without welding pipes back together or using some sort of clamp/fitting to reconnect cut pipes.
Not sure where the pipe is recommended to be cut - if it's somewhere readily visible, or underneath a panel or something.
eurocharged charged me for 6 hours labor
i went with catless downpipes so wanted to save factory cats if i ever sold the car the new guy will have the option to go back.
Without CATs, don't you get a check engine light?
From what I was told, unless you cut the existing pipes, it's a huge job to remove the factory exhaust in order to swap it out.
Move Transaxle and oil lines, lift engine etc...

This exhaust was done in Germany by OPUS.
They are a very good company but logisticcs make it very difficult for them to do business in the US.
This was a tune and exhaust upgrade.
