February 13, 201510 yr After a 3inch track day exhaust that passes noise test 103db but still needs to sound good got a nurspec r and just too much for track must be 3 inch
February 13, 201510 yr Drive by or static limit ? Www.cobrasport.co.uk one idea. I have the turbo back sports cat trackday friendly system. static is 96db not sure what it is when driving by though. Other people say it's sounds good ! It's got a twin resonated centre
February 13, 201510 yr Author Yer static bud i know someone said the miltek with one resonated section passed static i had a toyo sports on before was loud and still passed at cadwell
February 14, 201510 yr Author Middle already resonated on nurspec need a new exhasut system as the nurspec is sold ay gambit
February 14, 201510 yr I'll message fonzey for you tomorrow see whay he did. If anything I remember he had to short shift because it was too loud [emoji35] not sure if he had swapped his yet though mate I know he had to goto the states on work shortly after not been back long.
February 14, 201510 yr Author Well im digging out blind for a milltek 3inch ah well i will have to keep looking
February 14, 201510 yr Cobra sport do a track day friendly exhaust system [emoji6] I bought a sports cat off them a few yrs back good fitment and quality for the price
February 14, 201510 yr Nur spec = possibly the loudest exhaust known to man !But the nicest [emoji106]
February 14, 201510 yr Stuck the bung in my exhaust when I had a long journey to do last year . It Sounded too quiet and lost 0.4 bar of boost due to the restriction ...... First lay by I saw I put it back in the boot where all bungs belong [emoji4]
February 14, 201510 yr Author Yer i do have bung but as savage said restricts the system i regret selling my hks silent hipower last year now
February 14, 201510 yr i use this item : ;) apexi active tail silencer when the engine exceed 3500rpm , the spring inside it opens and the exhaust back open / empty sorry for my bad english :(
February 14, 201510 yr Author Thats pretty good bang. But id sooner find a milltek or similar thanks for help though guys

February 14, 201510 yr Not a problem mate !Removed! hectic day so far looking forward to getting some vodka down this exceptionally dry neck later [emoji9]
February 15, 201510 yr The two "go-to" choices are: Revolution 3" System: http://www.revolution247.com/catalogue/shop-by-category-exhausts-revolution-exhausts Or The Cobra Sports Trackday system: http://www.cobrasport.com/index.php/cobra-sport-exhaust-products/subaru/impreza/subaru-impreza-wrx-sti-17/subaru-impreza-turbo-track-day-turbo-back-system-with-de-cat.html I've been taking my prodrive backbox in the boot, so if I get flagged - it's two bolts to swap out to that (its very quiet). Thinking of bumping up to the Revolution system though later in the year.
February 16, 201510 yr Might have seen it http://www.scoobynet.com/full-cars-breaking-for-spares-438/1019844-big-spec-bugeye-prodrive-sti-breaking-2-1-build-sc40billet-alctec-whiteline-bcs-more.html cobra track friendly full 3inch turbo back system with full de catted down pipe/centre section and back box sounds great without being to loud passes most track day noise tests with any suppressors needed etc does have small dent in pipe doesn't affect system or anything but it is there £250
February 17, 201510 yr Author Yer seen it pete its not my cuppa that one but the cobra kne is mega quite i been told
