BMW Performance Headers & Downpipes for BMW 3 Series E90 (2006-2011)

Clear BMW chassisChange Your Vehicle

Headers are a bolt-on component that will make a huge improvement in how your BMW performs. As a replacement for your factory BMW exhaust manifold, our BMW headers provide a more direct path for exhaust gasses leaving your engine. Headers prevent your BMW's exhaust pulses from 'fighting' one another as they leave the head. The end result is that BMW headers give you more power and torque, and you'll love the high-winding top end push that a free-breathing engine exhibits. BMW headers are a must-have if you're doing any engine modifications on your vehicle. Along with a cold air intake, BMW headers provide the free-flowing exhaust necessary to get the most power out of your motor.

Adding headers and removing catalytic converters from the exhaust is one of the top things to do to make more power. The factory put the cats in the stock exhaust manifold which restricts exhaust flow. But any race or track car will want to run without cats to gain the most power and torque. We used these on our in-house 325i project car on our way to 272hp. These Supersprint stainless headers are a true tubular, equal length design that bolt up for an immediate power gain. With no cats and a race exhaust you can expect to gain 15-20hp over the stock exhaust setup. Power gains with a cat section depend on the type of cat.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Section 1 / Catalytic Converter Options
You have a few different options for the exhaust immediately after the headers (known as 'section 1'):

 

Stock Section 1 Cats*Sport Cats*Straight Pipes**

* - you will need to have the rear O2 sensors extended to the new location of the cats. Special software or stand-alone engine management may be required to prevent fault codes and other conditions.
** - any cat-less section is sold expressly for race or on-track use only. Special software or stand-alone engine management may be required to prevent fault codes and other conditions.

American Racing Headers is a performance exhaust manufacturer that specializes in high flow header systems. They have made a huge name for themselves since their creation in 2005 in the domestic world and are venturing into the Euro scene, now offering premium exhausts for BMW. Made 100% in the USA, located in Deer Park, New York, of 304 stainless steel and hand welded to ensure the best fitment possible, these headers and exhaust systems are perfect for high performance and long term durability. Within just a few years, the were noticed by the "Big-Three" auto giants in the US and were soon the Tier-One supplier of racing headers for the Ford Cobra Jet Mustang, General Motor's Copo Camaro, Chrysler's Drag Pack Challenger, and the Dodge ACR-X Viper.

Sound Example from American Racing Headers:

As shown above, their E9X Header to Axle exhaust system's are perfect for giving your vehicle both a much more aggressive sound when paired with stock or aftermarket exhausts and unleashing the potential power of your 4.0L S65 V8.

The first parts down the line are their signature high flow headers! Using header primaries that are larger than stock and merge collectors that are in-house designed to improve flow as much as possible using a vortex scavenging design, these headers allow a significant improvement in total exhaust flow resulting in higher torque and horsepower numbers throughout the RPM band. The primary tubes come in 2 sizes: 1-5/8" diameter or 1-3/4" diameter. 1-5/8" primaries offer a moderate improvement over stock allowing for less restriction directly at the head and down to the collector. This size will better benefit vehicles that are mostly stock and with a tune and performance intake. 1-3/4" primaries offer a more sizable improvement, allowing for vehicles built much more aggressively to benefit greatly. Vehicles with performance cams, higher performance tunes, and other heavy modifications will be able to efficiently expel exhaust gases thanks to the lower restriction and will be able to see much higher numbers on a dyno and feel a difference on the street or strip. 

After passing through the manifold, the exhaust gases come to the second component of this performance system, the 3" X-pipe that is available with or without catalytic converters. X-pipes are great for two reasons: More even exhaust flow throughout the power band, thus improving engine efficiency, and an steadier exhaust note that gives off a super-car feel instead of the traditional pulsating that gives your car an old muscle car sound. This helps express the natural sound of the exhaust both at idle and under heavy acceleration. Catalytic converters are the next option to choose from. Building a car for the track only? Cat-less is the answer. Looking to drive your vehicle both on and off the track? The 200-cell high flow catalytic converters keep you both road legal and they are virtually restriction free for continued high flow exhaust. In addition, the x-pipe is built with O2 bungs installed, ready for your sensors to be reinstalled.

Last in line is the center section with two 3" exhaust pipes available with or without resonators. Some people prefer to eliminate the resonators to get the most aggressive growl out of their exhaust as possible, and others like to keep these in place to help eliminate high RPM drone that can become slightly irritating when driving long distances. More of a personal preference, this just allows for even further exhaust customization.

Product Features:

  • 100% Made in the USA - Never Outsourced
  • Made entirely of 304 stainless steel 
  • 3/8" thick laser-cut flanges for a warp-free seal
  • 1-5/8" or 1-3/4" exhaust header primaries for higher flow
  • Hand-ported TIG welded inlets
  • Optimized primary tube routing for superior fit and performance
  • Merge collectors complete with internal welded scavenger spikes
  • Catted systems feature 200 cell metallic substrate catalytic converters for extreme durability
  • High flow x-pipe for exhaust flow balance and smoothness.
  • Dual stainless 3" center-section pipes available with or without resonators
  • Hardware for assembly included

If you decide to purchase the catless system: This part alters or deletes the emissions equipment on your car. Removing the primary cats will result in a check engine light and faults for the missing cats. Special software or modules will be required to prevent the codes but this setup will not be street legal. This was designed for race and track use only. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.

BMW N52 E90/E92 328i Exhaust Headers Tubular Stainless Exhaust Manifold 06-11, LHD only

This exhaust manifold fits the E82, E90, E91, E92, E91 chassis BMWs with the 2.5 or 3.0 litre, 6-cylinder engine. We think these might also fit the 323i but we are not 100% sure.

Dual 3-into-1 design for optimum street performance.

Estimated power gains from 10 – 30 BHP depending on other supporting mods.

Comes with the gaskets and everything you can see in the pictures.

The whole manifold has been TIG welded so the chances of this ever failing are virtually zero.

We know this manifold fits EULEFT HAND DRIVE vehicles, they can be fitted to right hand drive vehicles with modifications that will require welding. The whole manifold has been TIG welded so the chances of this ever failing are virtually zero.

Please ask before purchasing if you intend to buy for a RHD vehicle so we can advise on the changes.

Pretext- Car: 2011 Bmw 328I x with N51 engine. (3 stage manifold built in.)

I have two possible set ups I'm considering...

First: AFE twisted steel headers with a Bmw perf exhaust.
Total cost: (including labor for exhaust) $2600 M/L. (ballpark estimate)
(A 50/50 of performance and sound)

OR

Second: AA Headers, AA Tune, Stock Exhaust.
Total Cost: $1760 (More bang for your buck)

I've heard the AA headers with the BMW perf exhaust and personally Its just not what I'm looking for. For that reason, I would keep the stock exhaust for set up no. 2. Plus, i would prefer to keep the cats on due to emissions, but I wouldn't lose any sleep over it if I dumped them with the AA headers. (I'm no tree hugger, but i do believe we should all do our part in keeping our carbon footprint to a minimum.)

I'm really torn between the two. A lot of people have a similar set up, but have removed either the primary or the secondary cats.

Need your opinions!!
