I agree, although I have an xpipe with HFC which is essentially like test pipes with secondary cats, the sound is sublime and transforms the car into a raw racecar sound.

The best part though is there is absolutely no drone or difference in quietness when you drive normally. This is a huge benefit in comparison to every axle back which almost always gives drone and gives a boomy bass sound to the low revs.

Catless just makes so much sense, especially with HFC or secondaries as there is no smell to worry about or anything. Really a win-win with no compromises
