OK, so I call XDP and let them know who I spoke with & what they told me, which is I need to force their resonator delete onto my turbo to make it fit. If I damage my turbo in the process they are not liable for the damage when they were the ones who are telling me to force the tube on there. I refused to do so as the truck is still under warranty & I do not want to void the warranty in case it did ruin my turbo. So I ask for a refund. Again, they tell me that there might be a 5-10% restocking fee for the mistake they made. Wow, mind-blowing!!
