Whats the most quiet setup de-catted? Im looking for more power but not the noise that goes with it. A case of custom system with huge centre silencer?
I have the japspeed 421 decat with spoon bpipe and standard backbox.
It isnt that loud, it is a bit raspy though but when in vtec the engine noise takes over.
Since i added the cams and 70mm throttle body and remapped again, the exhaust in idle just burbles away sounds nice.
Can try get a video for you tomorrow if you want.
