The ITG is without doubt louder than the Twintake IMO. Ive had the ITG personally and ive heard the twintake on a few cars. I also had the APRs Golf R which runs this VWR intake and in all honesty i didnt realise there was an intake fitted until i had a look. No big whooshes or darth vader noises etc. Im not sure how much of the engine noise is attributed to the intake or the exhaust but i was pretty impressed by its quieter operation.
....The VWR intake being much quieter than my Twintake would be a disappointment and deal breaker in my case.
The choice of an aftermarket air intake tends to be based on the following considerations (not in order of importance):-
- Performance
- Standard of manufacture
- Ease of maintenance
- Sound
- Appearance aka 'Eye-Candy'
- Price
Enjoying sound is an important consideration for many drivers, just as it is when choosing an exhaust system.
