    Trust me if you have a Turbo Cayanne you must do this...

    to your SUV. As I posted earlier my muffler was taken off and straight pipes run from cat. I was amazed when I picked the SUV today. The sound is the best sound I have ever heard from a V8. It is deep and mellow but the weird part is that it is not loud. I was told that the turbos and big cats displace the sound. So it might not work as good or another words be too loud in the Cayenne S. At all speeds including highway there is no res or vibrations. Even the Brumos racing group who put it own were taken back of how good it sounds. So if you want the beast to come out and play but yet concerned over your neighbors you might want to try this. It will save you many dollars and time waiting on the PSE

    Re: Trust me if you have a Turbo Cayanne you must do this...

    Right, you increase sound but you change backpressure too which has a negative effect on performance at certain rev levels. I know that you might not feel it but this is what I heard from the source which plans the "real thing".
    If the world would be that simple...

    Re: Trust me if you have a Turbo Cayanne you must do this...

    You are absolutely right. There now seems to be some turbo spool lag where it was not present earlier. Not bad at all but you can tell. Great observation by the way. I wish the PSE's would have this deep V8 sound when they come out but being typical they will probably restrict sound to 3000 RPMs like the early 996 PSE's.

    Re: Trust me if you have a Turbo Cayanne you must do this...

    No no, with the swith ON/OFF, my 996 sounds like a mad barking bulldog from 0rpm all the way tp 7300rpms!!!
    This is what I love about the PSE, you don't have to climb in the revs to enjoy the noise!
    Fanch.

    Re: Trust me if you have a Turbo Cayanne you must do this...

    You should've taken it onto a dyno before and after you removed the muffler - then you would see if/were losses are...

    I guess some people don't care about power losses on a SUV. The sound is great indeed, heard a Cayenne Turbo with a prototype sport exhaust a while ago and all I can say is WOW.

    Re: Trust me if you have a Turbo Cayanne you must do this...

    Yes, you are right. As my pics show I added small tube exhaust on each pipe and still the sound is great. I did this in response to RC's message. And to be honest with you it does seem to perform better by adding backpressure back into the system. But I was always told that on turbos back pressure was not important. So either RC was right or like a placebo it feels more powerful?!
