R35 GTR Full 3.5" stainless steel exhaust system - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

ACspeedtech · 31st July 2012, 11:43 AM

Due to current interest, I thought I'd show a few recent views of our full 3.5" stainless system available for the R35 GTR.
The ACspeedtech 3.5" full exhaust comprises of Front Y-Pipe De-Cat, Mid-Pipe and Rear Silencer Section.

Noise Output for this full system is 97dB at 4,500 rpm Static Test. The note is a rounded tone, yet is crisp under load. Many variations of silencing were tested before this was decided upon, keeping the drone under control was a priority and giving a volume that is acceptable for daily driving and extended touring also. Both of these requirements have certainly been achieved any we are proud to offer this drone-free and liveable with custom premium quality system.

Full T304 Stainless Steel Construction and features V-Band Clamps to join the separate exhaust sections together ensuring the best possible fitment and sealing between the exhaust sections.

Large 3.5" / 90mm Bore Pipework for maximum unrestricted exhaust gas flow to support 850hp, an option to move up to 4" pipework is available for 1000hp applications, please contact for details. Also available is an option for even more silencing for an even lower db output, again, please contact for details.

Mandrel Bends formed to provide the smoothest gas flow exit, superior to many existing designs.

Our Y-Pipe in twin 3" merges beautifully with Mandrel Bends into 3.5" Centre, providing the smoothest gas flow.

This exhaust is used throughout out tuning packages but is available on its own at a RRP of £1500 (currently a limited VAT free offer!) If anyone has any queries, please don't hesitate to contact us.

UPDATE: We have now tweaked the design of the rear silencers to remove even more cabin noise, still with the same signature noise and tone outside of the car and under throttle, yet a few db quieter at idle and cruise for a more enjoyable driving experience.

We are well aware that a loud and poorly silenced system will sound great... initially. Yet can be tiring to own, especially on journeys. The key is to design the system to give the noise and tone of the GTR that we all love, yet keeping the cabin noise to a minimum and removing the drone that even a simple y-pipe can bring.

Added a few pics to the trader section:

The cost for the full system is currently £1600 (correct 10/10/12) although we can happily make a special offer to members!
