Being installed by AOB as I type this message. I was a bit shocked when the service guy said it would be about $750. I would expect the test pipe install is super easy, the car is already up, just take off the cats and bolt on the pipes. 15-30 minutes? My question is, how long does it take to do the springs? I'm fairly confident JV will see the work order and make it right, but just in case, I'd like supporting data from others that have had this work done. Thanks.
