These exhausts replace the ones in the fenders. To be honest, they play very little role in the creation of the sound of the car. The reason for this is that the car’s original double cats break up the sound waves. Once it leave the cats, what’s left of the sound goes through the central muffler, which is nothing more than an empty decompression chamber. So once they reach these mufflers, there's no sound left. This means that even if we fitted a pipe going straight through to the tail-pipes, we would still have virtually no sound. Therefore, this version is only there should you need to fit a stainless steel muffler.
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.
On average they take about 2 hours 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. It is preferable, but not essential, to remove the rear bumper first. You will need to use a car hoist. Be prepared to buy new entry sleeves, or have some already to hand.
To ensure that our exhausts are fitted under the best conditions, a mounting kit containing: stainless steel bolts, stainless steel lock nuts and high temperature copper grease, is included with your exhaust. Please note that the entry sleeves are not included in the kit. It is essential to use OEM Porsche quality sleeves and clamps to ensure there are no air leaks. An air leak would ruin the sound. We recommend you use the copper grease on the bolt threads and in the sleeves and clamps when fitting.
