I have posted an update since this post and i am convinced its the backbox causing the vibration so i am booked in next week to have it removed and sleeve tested to see if this stops the vibrations.( I used an app on my phone to test the decibels outside and they were 68-70 and about 65 in the cabin on cruising and part throttle)Yeah I feel the same when I start it definitely vibrates my front door from the street. It definitely is the 3" piping that makes it a little much and I feel like I get a bit of a throttle lag with it. However I have read on this forum people say 27won has the loudest exhaust when you compare the popular ones (greddy, 27won, borla). Let me know how the 27won compares when you get it as I was originally debating between the two myself but went with greddy due to the price and popularity. The sound rating on the greddy is just 90db which is just up 6 from stock. I guess everyone has different options on what's loud or not. I think in the meantime I may put some soundproofing in the area where the spare is housed and see if that helps. Good luck!
If this fails then i will try a smaller thin resonator to replace the big box type, this should hopefully work! I got the greddy cheap so dont mind spending money on it to create my perfect set up
I will re post once tests have been carried out.
