Active Autowerke is proud to announce the release of our Signature F8X M3/M4 Exhaust System.
This system is the result of countless hours of R&D to obtain the perfect combination of performance and sound. Constructed of 100% 304 TIG welded stainless steel, we have created a modular exhaust system that will provide enough flow to support power levels way above the stock S55.
The stock S55 midpipe is a dual pipe system from each turbo that leads to the rear muffler. The resulting sound is far from pleasant, and without any real scavenging effect the turbo lag is fairly pronounced. By converting to a single 3.5" pipe directly after the downpipes, our system promotes exhaust scavenging along with higher exhaust velocity to produce a quicker spool, more power, and a much smoother exhaust note.
We believe that we’ve built the best performing exhaust on the market. With the reduced back pressure and large single-pipe design you can expect exhaust velocity to remain as high as possible throughout the entire system. Our design is also capable of handling much higher power levels than stock. It’s over engineered to have no issues handling the increased exhaust volume from extensive modifications including turbo upgrades. All Active Autowerke exhausts are designed and manufactured for performance, and our S55 exhaust is no different. Instead of copying the OEM exhaust, we started with a blank canvas in order to create a system as close to perfect as possible.

Almost a perfect fit for 2002 Avalon
The only difference from the old starter to this one is the old hardware had notches for the electrical connection and the old starter had a longer terminal post so I couldn’t swap the hardware successfully.
Instead of returning it because I don’t want to walk to work again I decided to grind a notch on the new starter.
Lucky for me it worked and I don’t show up with my uniform sweaty in a retail job anymore

Invonveniencia de reconstruir piezas como arranque, alternador.
Instalé este arranque en mi Camry 2002. Traerlo por Amazon a Caracas me costo la pieza y gastos de envío $112. Hace 8 meses se reconstruyó el arranque original con un costo de $180. Se dañó y decidí comprar uno en Amazon. Fue la mejor decisión.

Perfect OEM swap
Size: (Pack of 1)
Perfect OEM swap for an Acura RDX. It's cheap and less than 5 minutes to install. It fits snugly, and it'll keep your car running the way it should.
