Product Details
This Borla Transverse Flow Notched Muffler features a 100% welded construction using T-304 austenitic stainless steel, which means it's built to resist rust and hold up over time. Originally designed for GM F-Body Camaros and Firebirds, this muffler's transverse flow design allows for a compact setup, often mounted parallel to the rear axle. Its universal nature means it can be adapted for custom exhaust systems on a variety of vehicles, offering flexibility in placement and sound tuning.
The muffler has a single 2.5-inch offset inlet and dual 2.5-inch offset outlets, with one outlet on the same end as the inlet and the other on the opposite end. This configuration, along with its reversible design, gives you options when planning your custom exhaust. The notched necks are specifically made for clamp-on installation using 1-inch wide band clamps, though the clamps themselves are not included. Inside, high-temperature continuous-filament fiber acoustic material helps manage sound, aiming for improved performance without excessive noise.
Because this is a universal part, you'll want to confirm its dimensions and outlet configuration will work with your specific vehicle's exhaust layout. The natural mill finish can be polished or brushed before installation to match your desired look.
