Brand | Flowmaster |
Muffler Inlet Size | 2.25 Inch |
Delta Flow. Finding an exhaust with an aggressive exhaust note that won’t blow out your eardrums can be tough. Luckily, Flowmaster has been in the business long enough to perfect their mufflers using their patented Delta Flow technology, which uses inner deflectors to generate increased scavenging inside the muffler, equating to less interior noise and an aggressive exterior sound. If this sounds good to you, then the Flowmaster 40 Series Delta Flow Offset/Same Side Out Oval Muffler could be what you’re looking for.
Universal Fit. The 40 Series Oval Muffler is constructed from durable, fully welded 16 gauge aluminized steel and has a 2.25-inch inner diameter. This muffler is excellent for the street or track and has no internal packing that blows out when muffler is first installed.
Modifications Required. This Muffler was designed to be used on mutliple applications, as it is not a direct fit replacement part. In order to install this Muffler properly on your vehicle, some modifications to the exhaust system will be required.
Warranty Information. The Flowmaster 40 Series Muffler is covered by a three-year warranty. Please check the manufacturer’s site for more details.
Application. The Flowmaster 40 Series Delta Flow Offset/Same Side Out Oval Muffler fits 1999-2025 GMC Sierra 1500 models.
