This pre-muffler fits the :
> 911 2.7L
> 911 3.0L
> 911 3.2L
For these cars the pre-muffler is the most technical element in the exhaust line. All 5 of our pre-mufflers resolve the defects present in the original part, notably the loss of pressure in the gas flow which disrupts the back pressure. Our exhausts enable the engine to release its rated engine power thanks to the linear compression of the exhaust gasses.
This sport version of the pre-muffler provides an improved gas flow. Its sound level is similar to the original which means you can replace the original part without increasing the sound level.
We also offer the following pre-mufflers :
> A standard 400 cell catalized version - (Reference : SCA 911 2 1 CAT)
> A 100 cell sport catalized version - (Reference : SCA 911 2 2 CAT)
> A sport version - with a Riva type sport sound - (Reference : SCA 911 2 2 RIVA)
> A racing version - super sound - (Reference : SCA 911 2 3)
Our exhausts all have the original interfaces, this means that their entries, exits and their overall dimensions comply with the original part. They can therefore be fitted as a direct replacement of the original part without requiring any modification.
This pre-muffler fits between the headers and the mufflers.
On average, this exhaust can be fitted within 1,5 hours, including the dismounting of the original exhaust. Fitting time will be faster if the exhaust you're dismounting is in good condition, just as it may take longer if the reverse is true.
It is preferable but not essential to use a car hoist.
Dismounting the original exhaust can be tedious and require specific tools, for example a small grinder to remove the bolts at the pre-muffler in-pipe. To facilitate the dismounting we recommend you remove the rear left wheel and shock absorber.
You should always tighten the bolts progressively across the whole set of bolts. Make sure that the muffler is correctly positionned before fixing into place.
For our exhausts to be fitted in ideal conditions, their price includes a mounting kit which contains: gaskets, stainless steel bolts, stainless steel lock nuts and high temperature copper grease.
