Frequently Asked Questions
Will this connect to the factory SPT midpipe?
No. Remark specifically excludes the factory SPT midpipe from this axle-back's compatibility.
Do I need to replace the midpipe too?
Not when the car has the compatible non-SPT factory midpipe. Remark also lists its matching mid-Y-pipe as a connection option. This axle-back is not interchangeable with the complete Sports Touring system.
Installation Instructions
Follow Remark's installation instructions for RO-TSVA-D4. Confirm the existing midpipe is a compatible non-SPT factory part or the matching Remark component before installation.
