About the Afterburner Vortex
This backbox fits a standard exhaust system.
Since its launch, in late 2002, the original Afterburner quickly became regarded by many, as the performance rear silencer for the Subaru Impreza.
We have spent many months working alongside exhaust experts Hayward and Scott, developing the Afterburner product even further, and are now very pleased to be able to introduce the new Afterburner Vortex
Whilst we have kept the great Afterburner exhaust note, we have greatly improved the gas extraction capabilities of the exhaust by reducing the pipework bends to a bare minimum (see image on right), and introducing an almost unique spiralled baffle section, resulting in the gasses literally being spun out of the exhaust, drastically improving power at around 5k RPM.
This results in our most powerful exhaust ever, due to greatly improved gas extraction, alongside a Japanese street racer style angled exit from the rear of the car (we also offer the Afterburner Vortex with a straight exit from the rear of the car - see options list below).
We recommend one of our removable baffles if using this product on the road
This thing rocks like the Hendrix of exhausts! A week ago I had a shiny WRX-Sti sitting on the drive with a standard exhaust and an important decision to make. Either save my money and use the old ScoobySport backbox kicking around from my last car, or splash out on something new – an Afterburner Vortex. Now there’s no denying that the ScoobySport sounds sweet and I was dubious as to how much of an improvement I would be getting for my money, but after reading the reviews I was convinced.
Best decision I’ve made since buying the Impreza. On tickover the Vortex dishes-up the flat-four rumble much like the ScoobySport but a little louder and a touch deeper. Floor the throttle though and whereas the ScoobySport gets progessivly louder and changes tone a little, the Vortex mutates into an awesome howl like some kind of menacing Ferrari. I can’t get enough of it – I’ve got the needle bouncing off the red-line whenever possible! Before the Vortex I had a car that felt fast. Now it sounds fast too! - R.Nicholson
Have just replaced standard factory fit back box on my B4 Legacy Blitzen with AfterBurner Vortex. The sound is amazing and my mechanic says it was the best fitting system he's ever seen! I would recommend the system without reservation - D.Swift
The difference is phenomenal, Subaru should have this as standard on all Turbos - P.Meredith
What an amazing exhaust! I own a Normally aspirated GX impreza and I have STi boys asking me what I have got under the hood! J.Sheward
WRX Impreza Type UK STI 2003/4 (new style) The vortex provides quite a noticeable difference throughout the rev range and in particlar 1st and 2nd gear. The slight turbo lag in 1st gear is completely gone, probably due to reduced back pressure. Did I mention how spectacular it sounds. Believe me the sound files do NOT do it justice. Quite simply outrageous bit of kit. :-) P.Weighand.
perfect fit, perfect sound - R. Fenya
The Afterburner Vortex will blow you away with great looks, a deep flat four rumble on tickover and low revs and an awesome deep throaty roar on acceleration. But most importantly improved response through the gears...the Vortex really does do what it claims to do. Never would have believed a back box could add so much to my Scooby - J.Mynott
I have always been into Cosworths and one thing they lacked was a great sound, the Subaru gives the sound and performance. The Vortex takes the sound to a new level and is absolutely amazing, easiest system I have ever fitted as well. - C.Moss
Just fitted the Afterburner vortex rear silencer to my MY03 STi and I'm totally shocked by the transformation. What an amazing peice of kit, the car sounds fantastic and the torque appears to kick in earlier and continues pulling right through the gears. Lower the rear windows, apply a generous helping of throttle and you could be forgiven for thinking that a Jet has just switched his afterburner on right next to your ear! My standard scooby smile, just got a whole lot larger! Awesome - J.Banbury
Excellent Deep Throaty sound and great looks, You can feel the difference in response in the first 3 gears - J.Ford
One word sums this product up Awesome! - R.Thorn
very pleased with the exhaust- sounds like it should do now! feels more responsive in first three gears as well - M. Lay
