Hello to you all. This seems to be my first post here. Recently I had my 997.1 Carrera S tuned. I installed X51 powerkit apart from the OEM sports exhaust due to the fact that it doesn't provide any hp gains. So I decided to go for an aftermarket complete sports exhaust system for beter performance. In more detail I added aftermarket headers, 200cpi race cats, mufflers and I combined those with X51 powerkit. On the dyno I got almost 410hp on the flywheel. No CEL lights, no problems at all. Tje car runs as if it is a factory job. I am really satisfied with the performance I got out of this whole kit, but I am dissapointed by the way the car sounds. It has become really noisy. The noise in the cabin when traveling is really really tiring and I have to say I begun to feel like installing a new exhaust. I contacted my tuner for that issue and he said it's hard to combine engine sound and performance at the same time according to people's needs and preferences. I don't really know what to do.... Some advice would be really apreciated. Also any of you had the same problem?

 

What aftermarket exhaust did you install?

 

I tuned my car @ Kraus-Systems. I live in Greece, but I had to send it over to Germany for the installation of the powerkit. This is a very good tuner, very professional, but the only disadvantage is that my car sounds like an airplane to the runway! Not to mention that accelaration through a tunnel in the motorway can make you deaf and can easily scare everyone arround...!!
I am looking forward to your thoughts. Also I don't know if there are any silencers I can install...
