I have 2019 hatchback and i just bought this used 2JR mid pipe and greddy turndown catback setup. I’ve been having real difficulties when fitting it up to my hatchback . 1. The donut flange off the catback is too small for the diameter of the mid pipe and is causing a small exhaust leak. 2. The oem spring bolts also aren’t able to sit even on the mid pipe because they sit to close to the welds 3. Not sure if it has to do with the hangers but the center of the vehicle has some heavy rattle coming from the exhaust. 4. The box hanger on the muffler does not bolt up to the oem bolt holes, so you have to add a bracket to offset the hanger to have it bolt up. If anyone has come across these issues please let me know what you did to solve them.
