I'm having some major issues fitting the cutout w/ mpp2 solenoid before the cat in the exhaust area under the car. It's a real pain in the ass. Ironically, there is a perfect place to put the cutout AFTER the main cat. My precats are gutted already, and I plan on buying a test pipe, so is this worth it? I'd basically be eliminating a bunch of pipe and the mufflers. Please provide any feedback, positive/negative.
