Catalytic Converter Replacement for BMW 630i (E63)

The headers (or called exhaust extractors) of the BMW 6-series (E63) straight six cylinder N52 engine comes with two catalytic converter as stock.

In most cases, the factory stock catalytic converters can last the life of the car. But things sometimes do go wrong with catalytic converters prematurely. A hard acceleration that creates sharp blow to the catalytic, e.g. floor the gas pedal, could damage the catalyst material, blocking the flow of exhaust flow and hurting engine performance. An engine that's burning excessive oil could also wear out a catalytic converter before its time. In addition, certain fuel additives can (and do) counteract and prematurely age the catalysts.

Since most of the factory fitted stock catalytic converters are made of ceramic substrate, it is brittle and might break if knocked or in the case of a car accident.

If you are experiencing a CEL (check engine light) and it shows P0420 code on the OBD-II scanner, then most probably you are having a 'Catalyst System Efficiency Below Threshold (Bank 1)' trouble or in simple engine, your Catalytic Converter is not working and need to be replaced!

So, we will remove the exhaust headers where the troubled catalytic converter is located.

This is how the exhaust outlets of the BMW N52 straight-six cylinder magnesium engine looks like, after the headers are removed (SEE BELOW).

We removed the faulty catalytic converters and replaced with a 'HIGH FLOW' cat., for better breathing and higher performance output. This HIGH FLOW cat has 200 cells and is less restrictive compared to the factory O.E. catalytic converter which normally comes in 600-700 cells per square inch.

The BMW 630i stock headers are installed back in position with the new catalytic converters. Everything is back in position and no Check Engine Light issue due to faulty catalytic converter, no P0420 code detected!

BMW M3 (E92) X-pipe Custom

Exhaust X-pipe (or called crossover pipe) and H-pipe synchronizes the balance of the exhaust pulses from each bank of cylinders, for V6 or V8 engines, based on firing order which increases velocity and scavenging from each cylinder.

There are various tests have shown that, the X-pipe improves torque and gives better horse power but reducing in-cabin exhaust noise over the other exhaust setup.

Here, we have custom crafted a set of X-pipe for the BMW M3 (E92) with full mandrel bent stainless steel and hand TIG welded.

Even though the factory fitted E92 BMW M3 centre section already came with an X-pipe, but the setup is restrictive because thre are two resonators and two catalytic converter.

The middle section of the BMW E92 M3 exhaust system is removed.

Replaced with a set of 2.5" stainless steel x-pipe exhaust section crafted by SUPERCIRCUIT Exhaust Pro Shop.

It is designed to be straight bolt-on, strictly no cutting or welding on the existing exhaust system.

BMW M3 x-pipe crafted with 2.5" mandrel bent stainless steel piping and hand TIG/Argon welded by our master craftsmen here at SUPERCIRCUIT Exhaust Pro Shop.

To purchase or for installation, please contact us or pay us a visit to our showroom in SS13 Subang Jaya Industrial Estate or the SUPERCIRCUIT authorized dealers nationwide.

Porsche Cayenne GTS X-pipe Custom

X-pipe (or called crossover pipe) and H-pipe synchronizes the balance of the exhaust pulses from each bank of cylinders, for V6 or V8 engines, based on firing order which increases velocity and scavenging from each cylinder.

There are various tests have shown that, the X-pipe outperforms H-pipe exhaust systems, especially as RPM increases, providing both better torque and power.

Here, we have custom crafted a set of X-pipe for the Porsche Cayenne GTS with full mandrel bent stainless steel and hand TIG welded. 

The factor stock H-pipe of the Porsche Cayenne vs. SUPERCIRCUIT stainless steel x-pipe on the right.

The X-shaped formation allows better exhaust gas scavenging, noise cancellation and better balance between cylinder banks. The result is a significant increase in power and torque but a reduction in in-cabin noise. Isn't it the best of both worlds?
