The Malian Race and TTE are 2 differents exhaust :
- "TTE" is similar to a real TTE/REMUS. German noise, not agressive to ears
- "Race" like it's nammed is for track with noise restriction
On warm idle, the "TTE" is very quiet, I could barelly hear the engine. On city at stabilised rpm, you can pass without anyone notice your car. The "Race" is exactly like motorbike engine with aftermarket "legal" exhaust > you hear the engine at idle. It feel like having an more powerfull engine. On full throttle, le "Race" is loud. Peoples can hear my MR-S from away (in meters terms). But it's not as loud as a full decat exhaust that can be heard from a mile in some case.
For quiet exhaust, I recommend you to go for the "TTE" currently "out of stock" probably because Russia/Ukraine war.
Here my Malian "Race" exhaust (4-1 PPE header and Sport Cat) :
