I know someone must have dynoed one by now. I'm assuming since I haven't seen the sheet posted that it must have lost power...

If they at least maintain stock power while lightening the car up a little, I would consider one...

 

I'll dyno soon.

 

I would e surprised if it did not gain a few HP. The same cannister on the WRX system added about 12 HP and the same cannister on the GSR setup added 7 HP. It seems to be a very free flowing muffler.

 

SpeedxxxRacer let us know when you do!

 

Reverend, the invidia exhaust was dynoed at SP engineering. The dyno was set up by the guys from Invidia on a stock s2000. And you can definitly expect more gains on s2000 with more aftermarket mods. Here's the link to the Dyno.

Companies that show these dyno plots REALLY need to describe their testing procedures. It looks like they did at least 10 pulls, and could have pulled the worst and best ones to show the +3.7 HP "increase". At my last dyno session, my results showed more "increase" than that as the oil warmed up.

 

Says they used dyno run 6 for the baseline and 10 for the exhaust, so yeah - there were other runs that we're not seeing . . .

But they are only 1 hour apart, which is good for reliability.

Gernby - what were you doing dynoing on cold oil???

 

I was primarily referring to the Redline MT-90 in the tranny. I wouldn't be surprised if there was a 5 HP difference between cold and hot tranny oil.
