Kline Innovation 991 turbo exhaust

PORSCHE 991 TURBO  Exhaust
 
The seventh incarnation of the 911, the 991 turbo has taken some strikingly beautiful evolutionary steps. A wider wheel base, and improved axel to engine geometry significantly improve the weight distribution and cornering stability. additional composites and aluminium to further reduce weight, even the exhaust has been somewhat improved over the 997. So how much could we really improve over the factory exhaust? Quite simply remarkably.
 
Performance
Available with decat pipes for optimum performance and sound, or with 100 or 200 cell HJS HDPE catalysts. The largest gain with decats is 38hp and 55nm. 100 cell and 200 cell catalysts produce 20hp, and 16hp respectively.
