I called Stefan today and as always the conversation was great. During our conversation he mentioned a couple of things you 997 Turbo owners might be interested...

They're releasing the 997 Turbo exhaust up until the end of the year and he also mentioned something which I found odd to say the least, OEM 997 Turbo's exhaust back pressure is even higher then the 996 Turbo!!! 0.44 against 0.36Bar on the 996... go figure.

 

Looking forward to his 997 TT products!

 

What were Europipe's backpressure on their 996 pipe? 6 PSI of backpressure is significant...

 

Just throwing this out because Im no expert, but could the new turbo design cause a different reading in the backpressure? Would this higher backpressure allow for quicker spool up then when the vanes open reduce backpressure thus producing better flow to get the best of both worlds? And this might all be throwing off the direct comparisons to the 996TT?
