Definitely not A. Be interested to see what you think between B & C under load on the road.
I'm going to have decat secondary with standard silenced X pipe then Larini valved rears but not sure if the silenced x pipe will cause a slight imbalance or restriction.
Interestingly I suspect the decision will not be based on what it’s like under load... the H pipe and decat pipes sounds awesome when driving hard, especially at high revs in 2nd or 3rd. However, at other speeds it’s a little bit drony and makes the car sound (at least to me) like an American muscle car...
All three of the clips are in sports mode, so valves open...Out of interest; are the stock back boxes with valves open or closed above...?
I go with B. Let's not forget the fabulous on road performance improvement the decat race pipes provide. The standard front pipes are so restrictive. B & C lets it breathe.
The video will presumably be normalising sounds levels so hard to tell which is louder relatively speaking, but I'd go for tone-less-drone any day.
Did you try X with the rest standard?
