The COBB 3 Inch Stainless Steel Cat-back Exhaust uses a unique straight-through muffler section rather than common chambered designs, which minimizes tubing bends, reduces back-pressure and keeps sound output below SAE standards. The outstanding craftsmanship and attention to detail are evident in every aspect of this cat-back. 

Exhaust gasses are guided through 3 inch diameter tubing into the center inlet of the fully 24 inch wide muffler section. Internal to the muffler, the exhaust gasses pass through a reversed Y merge, efficiently splitting the exhaust into separate muffling chambers on each side of the canister. 2.5-inch outlets emerge symmetrically from each side of the canister and direct the exhaust out the rear through quad polished exhaust tips. 304 stainless steel is used throughout the exhaust construction. All components are meticulously TIG welded for outstanding appearance and strength. Four custom exhaust tips fill the factory bumper cut-outs perfectly, protruding just enough to show off the COBB logos etched into the top of each polished tip.

Cobb perfection

Just what I wanted, more rumble for my sti, but not too much. Fitment was on point as expected. I bought 3" 2 hole exhaust gaskets to use, the one from cobb looked a little questionable. Also do not forget your stock downpipe to aftermarket exhaust adaptor and a new donut gasket while you're at it. Nobody like a leaking exhaust.

We appreciate the tip about using 3' 2 hole exhaust gaskets and the reminder about the downpipe adaptor and donut gasket. We want to make sure our customers have the best experience with our products. Thanks again for choosing Subimods!
