Added NPP Exhaust to 1LE Dyno Comparison
2013 1LE Standard then changed to NPP
Test conditions:
Six videos attempting to capture the sound differences: http://www.youtube.com/playlist?list...wwx0KROmJmXGIU Blue is Standard Exh - Red is NPP Exh Last edited by Southern Comfort; 09-27-2013 at 04:43 AM. Reason: added youtube video |

Thank you for doing this. Not having air quality hurts the analysis, and I am sure the heat and humidity of the second day had an effect, and we have no idea on barometric pressure, but I think it supports the my theory that the NPP system is worth little to nothing in terms of power. For those that like the noise, it may still be the best bang for the buck. Again thanks for the effort. Very interesting.

What I see is 10 more HP at peak revs, and a tade more tq! Even though peak numbers are the same, you can see that up top the engine is breathing and pulling a tad stronger! I would not say it does nothing for power when it clearly does... Add some mods and that top end with the NPP exhaust will start to show even more! So if you want to keep a bone stock car it's fine, but add standard boltons I would want the NPP as I think it would clearly perform better.

Ron at Vengeance pointed out the same and marked the graph accordingly. |

Only real benefit I see is looks and weight.

Could it benefit from a CAI system? Maybe if the engine breathed in better the benefit would be more manifest.

Did you get a chance to weigh it? Not sure if anyone has made a concrete difference in weight between the stock exhaust vs NPP. Just curious.

No way I could justify almost a grand for that. It may not sound as refined but changing mufflers or muffler delete seems like a better move from a financial standpoint. The twin pipes look cool. Just not 1K dollar cool.
