After months of testing, Injen Technologies develops the all new SES1899TT, the axle back exhaust system for your 2008+ Evolution X that delivers the perfect tone at wide open throttle. Engineered with pride in the US, tuned and proven on the track, this system was designed to perform and look like a classic time piece. With Injen’s signature series embossed logo shinning across the length of the muffler, your competition will be hypnotized by the explosive power resonating out of the perfectly match titanium tips.
