The best exhaust bolt on your your dollar!
The VAC by Fabspeed resonated rear X-Pipe offers improved exhaust gas flow for your engine, crossing over at an ideal location with the correct divergence-angle to offer gains over what is already a fairly well made OEM system. The lack of restriction combined with the tuned angle dramatically improves scavenging during the combustion process and offers a very large gain for what is a seemingly simple exhaust component. 49 state emissions legal performance!
Its skills like this that make Fabspeed our choice partner when it comes to offering solutions that improve what is already a skillfully engineered automobile.
Fitment is spot-on and fits tightly to the body without reducing ground clearance. The entire system is made from 304 stainless steel, and is 100% computer-bent for accuracy on every system. Welds are precise and will not crack, warp, or fatigue. The Secondary Catalytic Converters are eliminated with this X-pipe, replaced by resonators so sound levels are kept in check yet restriction is reduced. Because these cats are not monitored by the emissions system, this exhaust is 49 state emissions legal*
Our (resonated) X-Pipes sound very sporty and more aggressive, plus they match well with most systems for customers who like a powerful sound at wide open throttle.
They are louder than the restrictive OEM secondary pipe, but are resonated to eliminate any drone or harsh frequency's many straight pipes suffer from.
A very good match for the OEM rear mufflers or VAC by Fabspeed rear section system. Can be used by themselves or with any other rear exhausts as well. Sound is clean and exotic vs. the OEM pipe and if you have a rear system that is already loud for your taste, we recommend our resonated X-pipe as a perfect match.
The beauty of this upgrade is the fact that power gains are realized throughout the power band from a very low 2300RPMs and up, with ZERO lost of power at any other point.
No less than 5WHP is had with peak gains toward the 6000+RPM band of +15WHP / 10 W/ft-lbs of torque (yes measured at the wheels). This is a great gain for a bolt on with such an advanced car along with no ECU tuning!
When used along with a high flow rear exhaust, gains over (30Ft/Lbs at the wheels can be had! Click for Video). ECU tuning can further improve power but is not required.
Our X-Pipe works as a replacement for stock, and when used along with our Fabspeed Cat bypass, or Fabspeed High Flow cat section; it doesn't require you to cut your primary pipes like competitors products. We use this same resonated X-pipe on our daily driven world record holding E92 M3 with a VF supercharger, so we can show that it holds up, doesn't impede clearance, sounds wonderful and makes terrific power. All systems are made on State-Of-The art CNC bending equipment and are each Quality Controlled by Fabspeeds staff before shipping.
-All: E90, E92, E93 - M3 2007-on
-The factory center section is primary cats w/ x pipe attached, it is one piece. Replacement of the factory X pipe with any other aftermarket unit requires 2 simple cuts of the OE system. Clamps are included and can be used to go back to 100% stock X pipe if so desired at any time.
-Fabspeed's excellent sound and performance
-Improve up to 30BHP with this bolt on exhaust upgrade
-Entirety made from 304 Stainless Steel, C.N.C. mandrel bent tubing for maximum performance and durability.
-Terrific flow for both naturally aspirated or boosted M3s

Release horsepower and torque, eliminate unpleasant frequencies (rasp) from your BMW, while also maintaining high flow cats and gaining a powerful sound! Save an additional $250 by buying together as a complete center section!
Our 100% stainless steel High Flow Cat Section for your E9X M3 has been called "The Best!" and our X-pipe the same... This package not only adds serious dyno-proven power, but does so while keeping your M3 49-state catalyst equipped* and sounding super mean!
Often times, removal of the Catalytic Converters located in the factory location causes emissions test failure, and fitting most aftermarket high flow cats not only reduces flow close to that of the restrictive factory units, but may also fail to adequately satisfy the factory Oxygen sensors long enough to keep catalyst inefficiency codes at bay. This is real frustration on a high end street car like your M3!

Each tip is individually length-adjustable, allowing you to arrange them in a staggered length, the same length, and even adjust for things like add-on rear bumper carbon diffusers... or to adjust for the slight difference between the coupe / convertible and 4dr rear bumper skin; perfect!

...what a SOUND it is... Sound in all capitals, but not because its overtly loud... its the amazing blend of V8 muscle with European howl that raises the hair on your neck. We feel without bias that this is the best sounding E9x M3 exhaust system ever; thats why we decided to partner with Fabspeed when we first heard the initial system.
You have never heard an E9x M3 sound so amazing, exquisite and exotic. After 10+ months on our development M3, not only is it a heart stopping sound for customers, but we never grow tired of it and even argue who will get to drive it for the weekend!
You will love the snarling, rich, aggressive tone like no-other under wide open throttle, and the smooth and subtle nearly OEM-like volume level during cruse. Surely, this is an amazing achievement in exhaust design and the best of both worlds- like a volume knob attached to the accelerator all without electronic gimmicks or vacuumed controlled bypasses. This is the experience Fabspeed brings to the table.... and maybe best of all? This systems offers all of the above, yet does not drone!
Unlike many systems for the E9x M3- even when used with an X-pipe and high flow section one, Fabspeed's Maxflo muffler technology lets you drive this system for hours and hours of time in total comfort.
Power & Flow:
Finally, no exhaust would be worthy of your M3 without power gains. No smoke and mirrors: tested on our development car that was an otherwise stock M3; fitted only with complete Fabspeed header back exhaust consisting of High Flow 200-Cell Sport Cats, Resonated X-Pipe and Maxflow rear muffler section and air filters.
Tested on a very accurate dyno with no ECU tuning, gains of up to 25-WHP can be had with cats and resonators! (ECU tuning is crucial on the E9x M3 to build power from the exhaust because the ECU constantly wants to adapt back to a stock-like power level). If you eliminate the cats, but keep the resonators and have the ECU tuned for your setup, we have had customers report gains of nearly 40HP and a dramatic difference you can feel from the drivers seat.
Flow is exceptional: good enough for our world record "fastest E9x 3 series" to run a 10.69 quarter mile in 2011 and produce over 620HP! We street drive this same exhaust daily and it is 100% enjoyable and livable in every day real world conditions.
