Wooooooowwwwww Simply WOOOOOOOOW
. That power output with just downpipe is amazing. I can say that Vishnu definitely know what they are doing. Only wish if they started making parts for our BMW market earlier. I believe n54 guys would love to run Vishnu downpipe if they had one knowing how much R&D and time they spent on developing a quality and functional products.
I have had used two other tunes before on my n54 and i couldn't be happier with the Procede.
Vishnu FTW and keep up the good work.
