This pair of intermediate pipes replaces the secondary catalysers. They can be fitted alongside a PSE or our mufflers (with or without valves). In reality, fitting the intermediate pipes will optimise the sound capacity of your mufflers, giving a better performance than fitting the mufflers alone.
These pre-mufflers fit the Panamera.
The Lambda probes used by the car's engine management system are located before and after the primary catalysers. Therefore, the replacement of these secondary catalysts by pipes will have no impact on the engine management.
Our exhausts all fit onto the original interfaces. By this we mean their entry, their outlet and their size are the same as those of the original part. They can therefore be fitted in replacement of the original parts without requiring any modification.
These intermediate pipes fit between the primary catalysers and the mufflers and can be found beneath the front seats.
On average the take about 30 minutes to fit, including the time it takes to remove the original exhaust. It will be faster if the exhaust you're removing is in good condition, just as it may take longer if the reverse is true. We recommend that you use a lubricant on the 3 bolts on either side at the top end, then leave the car to cool before removing the original exhaust.
You will need a car hoist for the job.
Remember that the bolts must always be tightened progressively across the whole set of bolts.... Make sure that the muffler is correctly positionned before fixing into place.
To ensure that our exhausts are fitted under the best conditions, a mounting kit containing: gaskets, stainless steel bolts, stainless steel lock nuts and high temperature copper grease, is included with your exhaust.
