AVO CatBack Exhaust WRX
The AVO cat-back exhaust system for the WRX is constructed from 3" stainless steel, and designed to bolt up to the stock locations/flanges. The high-flow design is rated of 86 dB, making it a good choice for noise conscious performance-oriented customers. Comes with a 3 1/4" rolled tip.
The stock exhaust system leaves a lot to be desired in terms of flow and audible excitement. After experiencing AVO exhaust, you will know exactly what it is that you have been missing! AVO exhaust system helps your turbo spool up sooner by increasing flow, improving throttle response and power across the board. Sound is just loud enough for driving excitement, without being intrusive for daily commutes. SPO's "most subtle full performance system."
