That sounds amazing! Very similar to many turbocharged V8 race cars.
Its funny to keep reading about people complaining how quite/weak sounding the X///M engine is with the stock exhaust... Little do they realize cause is the factory catalyst. Once removed the true sound of the V8 TT w/ 600+hp comes to life. I can't wait to put my downpipes on in a few weeks. |

I will see what I can do, maybe get my wife to video me cerraring down the road like a toss to record my exhausts sound NOT!! all jokes aside I will do some regular driving speeds so you can hear idle and low revs It's actually sounds quieter at low rpm with the akra fitted than before with SS DPs and the OEM bitch can. The sound was very farty like since the engine was breathing more air down the OEM rear section and it sounded a little wierd to say the least. Now at idle and low rpm, it's sounds like there are 670 Horses biting each others asses to kick out. On pull away it settles the irritaiing flapping sound I got before (a bit like putting some cardboard in your wheel spokes as a kid to pretend you were on a Harley) and now it's sounds like a proper V8 TT On flat out it sounds a little raspy and high pitched like a Ferris CS stradale. (I had one, so sorry of analogy is a bad one) Stay tuned, shoot me a pm if anyone needs any assistance on this as the whole project was a first since there were no real write up on the SS DPs before I bought mine, plus the ESS 100 RON tune and finally the 5 month wait for the Akra. |

This is ESS dyno of 95 RON tune and SS Cat-less DPs
I have the 100 RON tune plus the Akrapovic Evolution Hammann makes 670 HP what they got that I don't? Maybe AJ can chime in here? Last edited by Bob MG; 04-20-2011 at 10:38 AM.. |

Check out the differences on the dyno above. First one is with stock cats and 95 RON fuel tune Second one is for catless 95 RON tune (NOTICE HOW THE CAT-LESS HEADERS ALLOW THE POWER TO GAIN AS MUCH ON THE TOP AS THE MID RANGE FROM STOCK, WHILE THE TUNE WITH OEM HEADERS LOSES THE POWER GAIN RATIO ON HIGHER RPM RANGE) I haven't dynoed but mine has the Akrapovic rear section which is good for another 10 hp and 15 torque, plus I have tune for 100 RON which I'm sure is good for anther 10 -15 hp also and a shit house full of torque ESS has tunes for both options as well as different fuel used I have 2 tunes from ESS: 1. catless 95 RON 2. catless 100 RON fuel |

So they use the turbo upgrade to get to 670hp, would explain why the kit is so bloody expensive. But on that note i would have thought that their kit would have made more, isn't your car making close to or 670hp without the turbo upgrade.
The car is 408kw stock and only 493kw with the Hamman kit, so thats a 85kw gain for $16,000 |
