IPD plenum and GT3 throttle body

[NickG]

I did put the IDP plenum and GT3 throttle body up grade on my 981. I noticed a slight increase but because these cars are so long legged in the gearing, its not an "in-your-face" improvement. Would have been interesting to put on a dyno for pre/post readings to see if match what IPD says.

The several comments on exhaust and manifolds. If you track your car, just be careful you don't spend all that money and then find yourself being black flagged at the race track because you are over their Deci bell sound limits. Particularly on front straights where you might hug a concrete wall and sound reverberates!
