I love the sound of an air-cooled engine but like a lot of Porsche owners you just can't help but wanting a little more - a little louder, a little deeper, a little raspier. So I did a little research, which lead to Gert Carnewal, based in Belgium, mainly because of his competitive pricing for Porsche parts. And instead of looking into an expensive full system replacement I went for a set of RSR Mufflers on an exchange programme, which basically means you can swap your existing mufflers for another set (used of course) that have been opened up, modified and then welded up again, resulting in a new and improved sound. You pay 800 Euros for the mufflers and get 400 Euros back when you return yours. A cost effective mod. And then there's an additional labour charge to have them fitted, unless of course you can do them yourself. Here's Mike as Northway just about to tackle mine today...
Step 1. Remove tips - typically the old clamp bolts need cutting as they tend to rust - it's a good job that Gert supplies some new nuts and bolts. Clamps and sleeves should be okay.

Step 2. Remove tips and straps.
Step 3. Fit new straps and fixings.
Step 4. Swap over the heat shields if they're good otherwise take the opportunity to replace them.
Step 5. Put back as you took off. 2nd tip back on so ready to fire her up...
Step 6. Send Gert your old mufflers and he'll modify them for the next customer.
Step 7. Enjoy the little louder, little deeper, little raspier sound of your air-cooled 911.
