Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars. Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves. Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction). By replacing the factory downpipe/catalytic converter with our Competition Series 4" Catless Downpipe, more power is unleashed! You will feel the difference instantly.

Our Competition Series Catless Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in house fabricators and built in the USA. The factory turbocharger turbine housing utilizes a V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensor is positioned at the factory location. Since the outlet of the turbocharger is 3.5" and the factory exhaust system is 2.5", the factory downpipes reduces size using short transitions from 3.5" before the catalytic convert and 2.5" afterwards. Due to space needed for the cataylic converter, the factory downpipes reduce in size using very short transitions. Since our catless downpipes delete the cataylic converter, we have more space. Thus, we use very long transitions. These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller. This results in less exhaust turbulence and backpressure which again improves throttle response and increase turbocharger spool times (less turbocharger lag).



Our downpipes are designed to fit perfectly with either the factory exhaust system or your aftermarket exhaust system. There are no compatibility issues whatsover. The downpipes will come by default in Brushed Finish. We also offer a Polished Finish as an option.

OPTIONS

Ceramic Thermal Coating - The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out. This keeps underhood temperatures lower and less heat absortion by nearby parts/surfaces. Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure. The ceramic coating also adds additonal corrosion resistance. We utilize the best ceramic coating possible. Our thermal coating can resist up to 2000F of heat. It is available in black only (all the other colors cannot withstand heat that high).

Additional O2 Sensor Bung - An additional O2 sensor bung can be added so that you can easily add a wideband o2 sensor and gauges so that you can monitor air/fuel ratios. The additional O2 sensor bung will come pre-installed with a plug so that you do not need to run the o2 sensor right away.

Optional EGT (Exhaust Gas Temperature) Bung - An additional 1/8" NPT bung can be added so that you can easily add a EGT sensor and gauge. The optional EGT sensor bung will come pre-installed with a plug so that you do not need to run the EGT sensor right away.

awesome!

Those Look Good. Would These Fit The F10 535 Also?

[Underated]

Cant wait!

...Consider it sold! Top of my xmas list for sure. Thanks guys I can't wait to see some dyno numbers on it!

[justinnum1]

best this would sound redonkulous with mperformance exhuast

[PeterM]

Great looking downpipes

[1.fresh.f30.335]

Do we have any sound clips or dyno numbers yet? I'm going to install it with a stock exhaust so I am interested to see what kind of noise difference I am looking at (hopefully a fair amount)

[TreDirtyFive]

wow, those look like vintage steampunk robot leg parts! bravo to be one of the first on the market with these. dynos next please!!

In General, when you install a DP with a stock system, you'll "hear" the turbo spool more, and it'll spool faster...rarely do you hear a noticeable increase in the sound...and if you do, it usually comes as a cabin drone, which isn't positive. Now, I'm making general statements, unsure WRT to this system...

I know what your saying, I've done a few set ups before and figured this car needs more turbo, more backfire but not too much more under driving, just a little deeper tone in my opinion. I think the dp would accomplish most of that, hopefully I don't get too much droning though, I haven't given that too much thought.

Can we get a sound clip? Also, the black heat coating... How well does it work and does it work to maintain stock heat levels or reduce heat levels when compared to stock? Or just reduce heat compared to non coated dp.

will this fit xdrive?

[lazycat]

I just had these installed, and i've never been more satisfied at a aftermarket part than at this downpipe. Amazing product! Completely transformed my car!

We've never tested these on an x-drive yet. However, we are currently looking for a tester so if you're interested give us a call at (626) 814-3403

I have x-drive and just installed my Catless dp. Was a little tight under there but i am loving it!! sounds amazing

Does it fix on RHD F30 335i? After install this DP, will the 02sensor will trigger the engine light? And price please.
