Catback recommendation needed

That’s interesting, My Tanabe had no fitment issues. Install was super easy.
I actually had a more difficult time installing the RB duals. However that was because my downpipe was slightly rotated at the V band causing my dual tips to look unlevel.
I will note this though, my Racing beat seems to flow more air than the Tananbe. When I switched from the Tanabe to the RB duals my car now overboosts and needs a little adjustment in the tune. I did go from a brand new Tanabe to an older Racing Beat if that makes a difference to anyone.

Thanks. I Just noticed, that the Tanabe exhaust tip isnt mounted straight on the canister. But on These Pictures, it looks like it is aligned orthogonal to the Back of the Car. Does the canister mounts diagonal? I am confused.

So far, my top 3 are:
- Tanabe medalion Touring
- Fujitsubo Legalis R
- RB dual
Hard to decide what to get. Concerning my requirements, what catback would have the best flow/Power to noise ratio?

The Revo has a pretty large canister. That is not acceptable in Germany?
Honestly I think the Fujitsubo Legalis R is the way to go if you want quiet with flow. Big muffler can, 3" piping. Bonus points on style (IMHO), and for not being a common choice.

OK, in summary, i have 4 candidates with the following Specs:
- HKS Super Turbo Muffler: 91dB Close noise / idle 76dB, 91 dB max (according to rhdjapan)
- Tanabe Medalion Touring: 93 dB max
- Fujitsubo Legalis R: 77dB idle, 97dB max (according to rhdjapan)
- RB dual tip: ? Varying Data. Some with 110db at wot
Its hard to make a decision without any flow Data.

With the car being this old you probably won't find good info on flow rates or DB ratings. Also, DB ratings can vary wildly depending on what is upstream of the cat-back, most any exhaust is relatively quiet with a stock main cat, for example. If you go with a high flow cat or mid pipe that's where the sound really comes out.
There's just general "this exhaust works well for me" or "this one seems restrictive" - you really won't be able to find hard data on how different ones flow. Especially since you're looking for a sweet spot between loud and restrictive.
