These mufflers only fit the:
> 997 3.8L (switch controlled)
The principle of an exhaust with valves is that you have a choice between a discreet sound and a very sporty sound at the flick of a switch. With the valves closed, the sound is a little more present than the original, and with valves open you have a very sporty sound. Unlike the OEM exhaust with valves, our system does not cut out between 45 and 75 kms/h. If you marry them up with our 200 cell sport cats, you'll be close to having the sound of a racing car. All the accessories are included (wiring harness and air kit).
Our range also includes the following mufflers:
> A Classic sport version - (Reference : SCA 997 3 2)
> An Ultima Recital sport version - (Reference : SCA 997 3 2 +) Best seller
> A sport version with valves (remote controlled) - Reference : SCA --7 3.8L 3 2 VT)
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.
These mufflers fit straight onto the catalytic converters.
On average it takes about 8 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. There is no need to remove the rear bumper. However you will need a car hoist for the job.
Once the exhaust is correctly positioned, the bolts must be tightened progressively across the entire set of bolts. When tightening the bolts on the sleeves at the cat end, be sure to respect the recommended tightening torque of 46Nm. If the exhaust fitting is insufficiently or overly tightened you could end up with an air leak, which would ruin the sound of the exhaust.
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. The sleeves for fitting the cats to the mufflers are not included. We would recommend that you use sleeves designed for the 996 as they are more resistant. We recommend that you use the copper grease on the bolt threads and on the sleeves when fitting.
