We own a '22 460 and a '24 550, there is no comparison when it comes to HP/torque. The 550 kills it is most every way. We shall see how it does on long term reliability......
Just FYI, if the cop is working radar/laser like we are taught, he won't have the radar on all the time. You are supposed to see the speeding car, estimate their speed in your head and confirm with the device. So by the time your detector goes off, he already has your speed recorded. Also...
Other than the little bit of rub in reverse, I'm loving AT4Ws on mine. My average MPG has dropped from 16.4 to 16.1 for city driving, but ride quality with the tires and Wescott kit still seems great to me.
I got an estimate to have the Magnaflow kit installed by Tandem Offroad here in Fort Worth. They want less than $400 for the install. Now I just need to here from some more 550 owners who have already done it.
