GReddy 11001130 Revolution RS Universal Muffler 3.0in 160mm Round

Vehicle Fitment

Universal - not vehicle specific. The GReddy 11001130 is intended for custom single or dual muffler exhaust builds and for vehicles not covered by GReddy's vehicle-specific exhaust lineup. Installation requires welding and cutting. This muffler is not a bolt-on replacement for any specific vehicle application.

Fitment Notes

• Installation requires welding and cutting - this is a universal muffler, not a direct bolt-on part. The builder must cut and weld the exhaust piping to integrate the muffler into the existing or custom exhaust routing. Professional fabrication is required.
• Inlet and outlet are both 76mm (3.0") diameter - verify that the inlet and outlet sizes match your existing or planned 3.0" piping before ordering.
• A 38mm (1.5") piping stub is provided at the rear of the muffler body for welding. Note that this rear stub is 2.5" diameter - not 3.0" - which is an important fitment detail for builders planning to attach 3.0" rear piping or a secondary tip section. Plan accordingly when designing the rear piping connection.
• The tip is welded non-removably to the muffler outlet and is NOT compatible with optional GReddy RS tip accessories (SUS tips, Ti tips, Ti turn-down, or GPP RS silencers). Builders who want post-installation tip interchangeability should instead select the tri-bolt removable tip variant, part number 11001131.

Features

• Straight-through internal muffler design maximizes exhaust flow by eliminating the directional changes, perforated baffles, and reverse-flow chambers found in conventional OEM muffler designs - exhaust gas travels directly from the 76mm inlet to the 76mm outlet through a packed sound-absorbing core, prioritizing flow efficiency and delivering the clean, aggressive exhaust note characteristic of the Revolution RS line at 3.0" piping scale.
• 160mm (6.3") round muffler body in a compact 300mm (11.8") length - the 160mm body is sized proportionally for 3.0" inlet/outlet exhaust systems, providing greater internal volume than the 140mm body used in the 2.5" variants (11001125 and 11001126). The larger internal volume contributes to sound management at the higher flow volumes associated with 3.0" exhaust systems without requiring a longer muffler body.
• Multi-density high-temperature resistant sound suppression materials pack the straight-through core - multiple packing densities allow different exhaust frequency ranges to be managed with appropriately rated material, producing a refined and controlled sound character rather than the raw, unfiltered output of a straight pipe at the same flow diameter.
• 115mm (4.5") single-wall stainless steel tip with GReddy logo is welded non-removably to the muffler outlet - the 115mm tip diameter is larger than the 105mm tip used on the 2.5" variants, providing visual proportion appropriate to the 160mm body diameter. The tip is 120mm (4.7") in length.
• TIG-welded 304 stainless steel construction throughout - TIG welding produces cleaner, more precise welds at flanges and seams than MIG, and 304 stainless provides high-temperature corrosion resistance for long-term exhaust service across the thermal cycling ranges of both street and performance driving use.
• Suitable for custom single or dual muffler exhaust configurations at the 3.0" piping scale - two 11001130 mufflers can be used together in a true dual exhaust build, or a single unit as a replacement or upgrade muffler in a custom single-exit system.
• Limited Lifetime Warranty.

Product Description

The GReddy 11001130 is the Revolution RS 3.0" universal muffler with welded tip - the large-inlet, fixed-tip variant of GReddy's Revolution RS universal muffler lineup, designed for custom exhaust fabrication on 3.0" piping systems and for vehicles not covered by GReddy's vehicle-specific exhaust catalog. It is the 3.0" counterpart to the 2.5" welded-tip 11001125, sharing the same straight-through internal design, compact 300mm body length, and non-removable welded tip construction, but scaled up to a 160mm body diameter and 76mm inlet/outlet for compatibility with 3.0" exhaust piping.

The 160mm (6.3") round body provides greater internal muffler volume than the 140mm body used in the 2.5" variants - accommodating the higher exhaust gas flow volume of 3.0" systems while maintaining the same compact 300mm body length across the full Revolution RS universal muffler range. The straight-through core is packed with multi-density high-temperature resistant sound suppression materials that deliver GReddy's characteristic aggressive but controlled exhaust note without the unfiltered harshness of an unpacked straight pipe at the same flow diameter. The 115mm (4.5") welded stainless tip is sized proportionally to the 160mm body, providing a visually balanced exit profile at 3.0" piping scale.

One installation detail to note: the rear piping stub - the 38mm welding extension provided at the back of the muffler body - is 2.5" in diameter, not 3.0". Builders planning to attach 3.0" rear piping should account for this step-down in their fabrication plan. The welded tip is non-removable and not compatible with optional GReddy RS tip accessories. Builders who want post-installation tip interchangeability should select the removable-tip variant, part number 11001131. Installation requires welding and cutting - professional fabrication is required. TIG-welded 304 stainless steel throughout. Backed by a Limited Lifetime Warranty.
