+1 for the Kline innovations exhaust...
I had an Inconel system fitted on my Turbo S recently , bought direct from Felix at Kline, great guy to deal with ....
So , I had the usual reservations about fitting an aftermarket exhaust, even after having mine delivered , I had it on my garage bench for a few weeks deliberating whether it would be a good idea or not.
It looked so good sitting there it was a great conversation piece and was almost an artwork ..!!
....but I trolled the internet & You tube ( E sysman's GT2 RS conversion was played over and over again, to listen to the kline on his !!, I recommend watching that just to appreciate his commitment to his vision) listening to as many Kline systems as possible, the Porsche sound with Kline is still the best imho.....
So , on it was fitted and .........I can thoroughly recommend this exhaust as it transforms the usually muted sound from the Turbo stock exhaust ( although it could be made to howl a wee bit in ' Sport mode' at high revs)
There is no perceptible difference at low speeds, a sound that is comparable to an angry dinosaur when on boost and on the over run , it pops and bangs like a good un......
on my way home after the exhaust was installed , I had the initial feeling that it was delivering a flatter torque ' curve' as it felt like the power delivery was more linear than previously experienced ... I still think that is the case , but only a dyno would truly tell but I will not subject my car to that ...
I love this exhaust, and it must be one of the best mods that can possibly be done to a 997 turbo to improve the sound.
