What’s your opinion

I just bought a 2015 SHO, I leased a 2014 so it’s been a while but this one seems faster. The dealer didn’t know anything but it had a rumble to it so sound like exhaust work. It has a K&N intake pipe and you can really hear the turbos and the **** out. Anyone know what might of been done and how I can tell ?

Nothing out there has beaten me 2018 bmw 750i, 6cyl turbo charger. Challenger scatback I just pull hard from them. I have tried those gps apps that tell ur performance. It’s all over the place but I mostly get 4.3-4.8 0-60 and 12.3-12.1. I’m putting coil overs in and upgrading the brakes. Downpipe and exhaust and stage 2 tuning.
