Hello,
Thank you for your feedback. Please note that the rear coupler is intentionally designed to be longer to accommodate a wide variety of turbo setups. As mentioned at the 3-minute mark in the installation video located directly on our product listing, this coupler is meant to be trimmed down to fit your specific application.
If you encounter any installation issues in the future, we highly recommend reaching out to the Subimods team first. We are always happy to provide troubleshooting assistance, technical guidance, or point you toward helpful resources like installation videos to make the process smoother.
Regards,
