Magnaride comes alive when you start dogging on the car. Put the car in sport or track mode and marvel at the performance. Even with 700+ hp in mine, i still love magnaride.
You have to decide on 3 things primarily, long term power goals, power band goals, and budget. Answer those and you will be lead to the best choice for your goals. That said...whipple for the win lol.
The mounts on the sides on the 18+ are different, it has a bracket that mounts through the bumper, the 15-17 use garbage pressure bracket the bumper clips into. Thats why the 15to17 guys have trouble with their covers coming loose and 18+ do not. My i5 autohause bumper installed without issue...
Seems to definitely be warmer than mine gets. I have the 170 degree thermostat and mine stays at 180 the entire time i am driving and has only creeped into 195 or so while in a busy drive through lol
