offer expires early March


The Revolution RS for the second generation Scion tC features large diameter 2.5” mandrel-bent piping which extends all the way to the front of the vehicle’s main catalytic-converter for maximum flow. Dyno testing shows gains throughout the usable power band. The aggressively angled compact Revolution RS muffler is aided by an extra-large oval front resonator to help control sound quality. Like all GReddy Revolution RS systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.


  2011-15 Scion tC (AGT20)
  Part number: 10118103 




The Supreme SP for the 9th generation, (FB) Civic Si features our signature GReddy layout, styling and sound, with new revised piping diameter. It is designed to be compatible with both Si models; coupe and sedan (using the optional 11050108 adapter.) The straight-through resonator and specially-made oval muffler with off-set extended tip allows the system to follow the Civics’ bodies lines and help reduce drone and high pitch frequencies. It also provides good power gains throughout the usable power band. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.

  2012-16 Honda Civic Si (FB) Coupe
  Part number: 10158209, for Sedan also use #11050108





The Revolution RS for the Lexus IS300 unleashes great power gains, with excellent sound properties, through a high performance cat-back layout. Sound levels at idle and cursing are surprisingly low, while at WOT (wide open throttle) the inline 6 cylinder sound of the IS300 is dramatically enhanced. The large 3” diameter also makes it ideal for additional upgrades and/or boost. Like all GReddy Revolution RS systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty..
