Fitted last night, so not much testing
done yet but here are my initial thoughts.
Install time of 5-10 mins max.
Throttle response is perhaps a tad better ( my main gripe with the R56 ) At below 4k revs it pretty much sounds the same. In the higher rev band, it sounds deeper, more induction roar. Traffic was busy this morning so didn't have chance to 'play' on way to work. Because of this i haven't had chance to do high rev gear changes to check for BOV noise etc. Maybe at lunchtime
Again, early days, but it does seem to rev a little more freely and idle more smoothly, but this maybe placebo
Next mods in order
Sprint Booster ( hate the non sport mode throttle, but hate the sport mode steering even more )
Alta Turbo Inlet Pipe
Alta Boost Tubes
GTT Stealth Cat
Helix Front Mount IC
After that 'i'll mostly be wanting front tyres'
