I wasn't planning to buy the complete F.I. catback and then delete the muffler. That's why I've recently inquired @Tony/Dan for them to ship me the TDX with deleted mufflers already, i.e. much lower costs, too. But still waiting for their reply.
If they cant do that I go with AAM shorties and search for separate suitable 2.5" midpipe/downpipe.
As for the noise level of this combo, it wont come near any headache threshold as far I've heard
here ;-)
In fact just the right tune to go with a Z. But on top of all, my TT will quieten down more compared to the NA in that video clip
