Ok so dilemma time, I nee to cut the noise on my DC5 a bit for my local track and evening sessions.
Current setup
Dc Sports full race system (about 2yrs old) manifold and decat in one with full cat back system (4†tip)
Readings at Brands
104db at 4K revs, 98.8db at 6K revs and 102db at 6.3K revs. So under load I was well on the limit
Looking at:
Fujitsubo RM01A (RHD Japan state as below):
Tip Diameter: 89.0mm
Pipe Diameter: 60.5mm
Fujitsubo:
- Idling Sound: 70
- Noise Near exhaust (6000rpm): 93
- 3000rpm: 83
- 5000rpm: 89
- Response 3000rpm~5000rpm: 101
Or
Kakimoto Regu.06&R (RHD Japan state as below):
- Main Pipe Diameter: 60mm
- Canister Tip Diameter: 90mm
- Canister Diameter: 130mm
- Noise Levels (Near the Exhaust): 93dB
I‘ve looked at a solid fab setup also and will call Alan later but my goals are:
No or little drone for normal motorway driving, perfect fitment to car and DC sport mani whilst being quiet yet noticeable and track friendly.
Anyone got experience of these on track who can share their knowledge and db readings as trying to void a bung t ok costs and want a nice free flowing and non restrictive setup.
Thanks
Carl
