The Titanium Catback Exhaust is a high-performance exhaust system featuring dual 114.3mm titanium tips. It is designed to be compatible with the TOM'S Racing Rear Diffuser (Part Number: TMS-52159-TZN80). However, installation with the rear diffuser requires some modifications and adjustments to the vehicle's stock components.

Installation Notes for TOM'S Racing Rear Diffuser:

1. Cutting/Trimming of Stock (Black) Lower Bumper Cover Diffuser Panel: To accommodate the installation of the TOM'S Racing Rear Diffuser, the stock lower bumper cover diffuser panel needs to be cut or trimmed. This modification is necessary to ensure a proper fit and clearance for the diffuser.

2. Drilling of Pilot Holes to Underside of Factory Body Panels: During the installation of the TOM'S Racing Rear Diffuser, pilot holes must be drilled into the underside of the factory body panels. This step is crucial for securely attaching and mounting the rear diffuser.

Installation onto OEM Factory Rear Bumper (Black) Lower Bumper Cover Panel:

1. Trimming of the Exhaust Tip Outlet Cutout Shape: To fit the Titanium Catback Exhaust onto the OEM factory rear bumper's (black) lower bumper cover panel, the exhaust tip outlet cutout shape needs to be trimmed. This modification ensures that the exhaust tips align correctly with the bumper cutout.

It is essential to follow the specific installation instructions provided by the manufacturer for both the Titanium Catback Exhaust and the TOM'S Racing Rear Diffuser. Proper trimming, cutting, and drilling are necessary to ensure a secure and proper fit for these aftermarket components on the vehicle.

Please note that modifications made during the installation process should be done with care and precision to maintain the overall aesthetics and performance of the vehicle. It is recommended to seek professional installation or assistance from experienced professionals to ensure proper fitment and avoid any damages to the vehicle's components.
