It fits flush in the right side wheel well. It comes with a Rockford P1 subwoofer appropriately chosen for the box's cubic volume and a Rockford Prime 250 watt RMS...
I just beat a DCT Golf R down in Mexico from a 20, 30 and 40 roll. He is making around the same power as me.
Fast shifts at 8k rpm, no lockout, no aftermarket shifter. It can be done. I don't recommend ramming it in to gear, give it firm pressure at the gate and it falls right in to gear...
I will be keeping my S550 for 3 more years to pay it off and then give it to my son. I had plans for boost but after seeing the new C8 Corvette, I could care less about this car. The C8 is in my near future.
Not who you asked but the '18 manifold and e85 completely woke my car up. The car pulls like a raped ape up to 8k and I put a lot of cars on stock 15-17 GTs. Mods are 18 manifold,injectors, jlt intake, cat deletes/exhaust.
Lund refused to grey these sensors for me when I asked which was fairly recently. I know you said you had them do it but maybe they aren't anymore? YMMV.

Yes, I tried every single thing that has ever been prescribed by people that have got their sensors to show ready. Absolutely nothing worked for me and I had to of put around 3k miles on my car while trying various things.
It seems to be very hit or miss on who's car can get the sensors green...
It's called making "friends." Friends that take small donations to ensure your car meets state requirements :)
That is the only way my car would pass tuned, even when I had factory cats in place.
The paint chips if you so much as even look at it the wrong way. Mine also had two bubbles on the trunk that the dealer was somehow able to hide when I looked at the car.
Also, while I was shopping for mine a few years back, I looked at a total of 8 S550's from different dealerships. Out of the...
