At first glance, you may be thinking, “wait a minute, ARH is making Euro car headers now?” Our answer is pretty simple, YES. In fact ARH already offers header systems E90/92 M3’s and Mercedes’ coupe’s and sedan’s powered by their 6.3L V8. What happens when American Racing Headers creates the first rotational firing, 6 into 1 long tube header system for the E46 S54 powered M3? Well, it’s definitely going to ruffle some feathers to say the least. Obviously we showed up a bit late to the game and that’s no secret. Wifly-city idu-2850ug-10g. You’ll play as one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. Left 4 dead 2-black box. This co-operative action horror FPS takes you and your friends through the cities, swamps and cemeteries of the Deep South, from Savannah to New Orleans across five expansive campaigns. But does that stop us from showing up fashionably late? Not a chance. Seventeen years after the car’s initial release, and every top shelf exhaust system manufacturer having had a stab at designing, re-designing, and improving upon BMW’s initial design, we took our collective expertise and from a clean sheet of paper changed the game in one swift move. Never before has a system been designed like this one, and we’re not just saying that because we’re ARH. We engineered and produced a system that takes S54 performance to another level. E46 M3 (S54) Complete Header Install Kit. S50 Euro/S54/M54 EGR Plate. BimmerWorld E46 M3 Exhaust by MagnaFlow - Rear. Using the highest quality materials, from the flange, tubing, merge collector, and optional catalytic converter, these are not your run of the mill - mass produced pieces. Through our immense efforts we’re reshaping the expectations of our customers and showing the market how headers are supposed to be done. Let’s elaborate a bit more on what makes this system stand out. What Makes This Header So Special? First off, the only thing at ARH from China is the occasional take-out food. This system is entirely 100% American made using 304 Stainless Steel. No outsourcing, unlike nearly all of our competition. E46 M3 ForumsLet’s start at the most important part, our 6 into 1 merge collector where all the magic happens. The collector features our merge spike welded inside for a smooth transition and excellent scavenging capability. It chokes down to 3” to increase velocity, and expands gradually to the 3.5” transition but it’s imperative to take a hard look at the engines parameters (engine size, usable rpm range, cylinder head design, vehicle weight to name a few) and choose a tube size and length that provides the least amount of compromise on a wider range of applications. At the end of the day, all engines are air pumps. Their main purpose is to draw as much air into the cylinder head as possible, make the biggest bang, and get it out and down the exhaust efficiently so that it can move the car down the road. E46 M3 Best HeadersWhen we approached this system, we wanted to use a rotational firing merge collector concept. We optimized the airflow by taking the naturally occurring exhaust pulses and arranging the primaries entering the collector so that these pulses create a spinning effect as they enter. This scavenges the air from the primaries and keeps the exhaust pulses traveling at optimum velocity.
