Custom exhaust system for Porsche 964 UK Europe

 

 Custom exhaust system for Porsche 911 in UK and Europe

 

Improved Performance

SuperChips Buckingham have completed back to back runs on their MaHa rolling road and reliably recorded 295.6bhp and 352nm. This is with a completely stock engine and a live remap. Driveability and tractability were also vastly improved over stock.

Take a look at our Dyno charts in our performance case studies blog for more results, or get in touch to discuss having your own custom Porsche racing exhaust system made.

The race manifolds/primaries are true equal length and are hand fabricated in 1.5mm thickness 304 grade stainless steel for longevity and robustness, weighing just 4.025kgs each. These compare favourably over the factories combined manifold/heat exchanger of 6kgs each!

The entire system, including all fixings and brackets weigh just 27kgs.

The system it replaces, which includes factory manifold/heat exchangers/balance pipe (14kgs) + cup pipe (4kgs), CAT bypass pipe (2kgs) and final silencer including oval exit pipe (10kgs). A combined total of 30kgs.

A completely factory stock system with CAT and primary/secondary rear silencer would be nearer 45kgs complete.

Weight savings of up to 18kgs at the rear and mostly beyond the rear axle, definitely contribute to better handling and changes of direction.

It is difficult to fabricate a race system to be quiet, but we have shown that this is possible in spite of the substantial gains made. Naturally this can be useful for track day enthusiasts. The system produces just 102db at 4-5000rpm static test, compared with the previous system which exceeded 110db under the same conditions.

A more aural character can be achieved by removing the heavy sound deadening material and removing one half on the internal baffling inside the single silencer. The system then produces a fantastic raspy howl and at just 104db. This is especially noticeable under acceleration and above 4,000 rpm.

Considerable testing in all driving conditions has confirmed the system is extremely quiet at motorway cruising speeds and there is absolutely no intrusive boom, feedback or unwanted vibration inside the car.

 

 

 

 
Construction

 


The system has been fabricated from 304 grade stainless steel and is satin finished, not highly polished. All welds are F1 inspired and gas purged for optimum flow and visual quality.

 

 

 

Each manifold in the custom exhaust system for your Porsche 911, feeds into a cylindrical heat exchanger that can either be CAT free or contain race quality 100/200 cell CATS (at additional cost).

When these heat exchangers are CAT free, internal baffling slows down the flow of hot gases to create efficient interior cabin heat.

If CATS are preferred, they are hidden inside the cylindrical heat exchangers and because of their high operating temperature, this alone produces ample heat for interior warmth.

 

The exhaust system can be fitted to all versions of the Porsche 964 from 1989 - 1993. This includes C4, C2, Targa, Cabriolet and RS in either 3.6, 3.8ltr or larger engine capacities.

964 Turbo and Dual Exit systems will come a little later once we have a customer's car to fabricate in situ, allowing us to produce jigs for a millimetre perfect fitting.
