Lovely, Lovely Titanium!
The Invidia R400 Gemini Full Titanium Cat-back creates the exact exhaust note you’d expect from any Subaru, especially an STI! I believe this is the exhaust that Subaru should’ve made from factory, something that makes the amazingly beautiful and unique boxer exhaust note, instead of the quite and disappointing exhaust note that they make from factory…
If you are expecting loud and aggressive from this exhaust, you may be wanting to look into a different one with less resonators. This exhaust isn’t per-say loud, especially compared to my previous exhaust but it does have a wonderful low and throaty sound to it, something you’d expect of a boxer engine (the interior/cabin note also is amazing and deep.) However, I am also running the completely stock down-pipe, up-pipe, and exhaust manifold, all of which contain catalytic converters so obviously the exhaust is going to be fairly quiet. If you are running a higher flowing header pipe or down-pipe (or both) it will most definitely become much louder. I will at some point be getting a different header pipe to increase performance and have the exhaust make a louder note.
Absolutely amazing exhaust!
