▀▄ eas | Macht Schnell 3" Stainless N54 Catless Track Downpipes

[anthony @ eas]

With a maximum output of 306 hp from 2,979 cc the 135/335’s N54 powerplant ensures exceptional driving dynamics at all times with all the power of a much larger normal-aspiration engine. Twin turbochargers each forcing compressed air into three cylinders ensure a standard of spontaneity never seen before in a turbocharged power unit. The big advantage of these relatively small turbochargers is their low inertia, avoiding excessive “turbo gap” – the moment which usually passes by until the turbocharger builds up its boost – typical of a conventional turbocharged engine. On the road, therefore, the turbocharged power unit of N54 variant offers all the power and performance of a much larger normally-aspirated engine.

Stock downpipes cause a major restriction in exhaust flow coupled with their small 57mm (2.25″) pipe diameter and numerous crush-bends with factory pre-cats squeezed in engine compartment. This results in excessive backpressure and excessive heat, which ultimately affects overall performance at all RPM loads.

Macht Schnell’s 76.2mm (3.00″) N54 Catless Track Downpipes allow instantaneous turbo spooling and ultra-low backpressure proving significant hp/tq gains that can be felt immediately after installation.

Mandrel-bent T304 Stainless Steel tubing is used to ensure constant exhaust flow is achieved by eliminating any restrictions, resulting in maximum gains and noticeable sound during turbo spooling. TIG-welded construction and Stainless Steel V-Band/catback flanges are durable as well as pleasing to the eyes. Heavy Duty exhaust gaskets and Stainless locking fasteners complete the package.

Stainless O2 sensor bung locations are mounted in the factory locations while introducing additional stainless steel thermocouple bungs for those monitoring EGTs.

Downpipe Features:
- 76.2mm overall diameter, eliminating restrictive factory pre-cats and crush bends
- 100% T304 Stainless Steel construction, using mandrel bends
- Precision TIG welded joints
- Heavy-Duty Stainless V-Band/Exhaust flanges
- Heavy-Duty locking fasteners and exhaust gaskets included

Just curious, do you need catted dp's to prevent CEL's or codes, I mean unless you have a BT tool?

I really dont wanna give my dealer reason to void my warranty if ever comes the time for warranty service but these are so damn sexy looking..they offer these ceramic coated too right?

Yes, if you don't run with cats, you'll get the Catalytic Converter deficiency error code. Though the dealer will notice the error light, most dealers (including the ones I go to), just ignore it.

The dealer I go to, I just say to my Rep, "I know why the service engine light is up, don't need to worry about it, nothings wrong with the car, just ignore it as it has nothing to do with any service updates since it's not related to actual engine work (aka oil changes, filter changes)." After you say that, my rep doesn't care.

I've been running catless for over a year, and with all my times I had to go to the dealership, none of them have ever complained about warranty issues etc. I think you'll be fine on this one, so far I haven't heard of any issues from any of our great customers.

how about BSM Cel fix?

I think the BSM CEL fix is for the most part generic so I wouldn't see any issues with running that just to get the CEL light away. There have been a few other things to get rid of the CEL light as well if you do some more research on it.

Obviously the first would be to just ignore it, or put some tape over it lol, but most guys want to get a permanent fix.

I ordered these from Jurrian and they were a breeze to install. Perfect fitment. I installed in about 3.5 hours in my garage using jack stands.
