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 part without requiring any modification. The straps for fitting these cats are included.
These cats fit under the car between the headers and the rear muffler. We recommend you start by disconnecting the plugs of the Lambda probes, then remove them when the cats are dismantled. It isn't easy to retrieve the Lambda probes so be prepared to buy new ones or have some already to hand. It is often necessary to cut the sleeves at the cat outlet with a grinder so be prepared to replace these too with OEM Porsche sleeves.
On average, it should take about 2 hours to fit them including the time taken to dismount 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.
You will need a car hoist for the job.
Remember that the bolts must always be tightened progressively across the entire set of bolts.
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, as well as the 2 straps, is included with your exhaust.
