The MST Turbo Muffler Delete replaces a component of the intake pipe designed to quiet down the noise of the engine on boost at the expense of performance. By replacing this muffler with a straight-through pipe, you get enhanced induction noise and reduced boost lag.Increases induction noiseReduces boost lagIncreases powerStandard OEM components are designed with a slit in the muffler pipe to disperse the air and silence the noise from the turbo. A side effect of this design is the hole creates turbulent air in the pipe which can also decrease engine power and increase turbo lag which is not a problem for a non-motor performance enthusiast. For the motoring enthusiast, however, this is a pointless trade-off. Losing power and noise is the worst of both worlds.The clever design of the MST Turbo Muffler Delete counteracts this, ensuring the muffler pipe is made from one piece of solid aluminium and completely sealed; increasing airflow by decreasing the turbulent air created by the hole.
