Our camera is terrible, and the sounds you were hearing were the microphone blowing out at random times. It took several extra runs to capture the sound all the way to redline, as the camera would automatically shut itself off from the loud noise.

Still can't get enough of that Porsche

Saw this on the blog this morning - great article.

Very nice!

Jack28 · 02-19-2009, 07:57 PM

Nice...

Freaken sweet!!

scotsman · 02-19-2009, 09:29 PM

how much different do you think the numbers would be for the sport vs race?

IND-Distribution · 02-20-2009, 01:03 PM

I wish we'd gotten the chance to dyno the Sport system this time around, but unfortunately Fall Line is very busy, and we'll have to do this another time.

Eisenmann's flow testing showed that the Race system improved flow by 32%, while the Sport system improved flow by 25%. Given that, I think it's safe to assume a 10-12hp gain with the Sport, but I'd like to test the system before giving any definite numbers.

I just rode with one of my friends here who has an Eisenmann Sport installed, I forgot how much I missed the Sport sound!

Just got my Race installed yesterday. Why wouldn't my come with the pipes to the cats like the pics here?

The Eisenmann system has a special relief to clear this convertible brace. The piping that the relief is cut into does not actually flow exhaust gasses from one canister to the other, but instead used to change the resonances within the canisters themselves, so a relief for the brace was possible.

Thanks for clarifying that Ilia

The pipes are not released for sale yet and were just developed. Look to be avail in 4 weeks or so.

Eisenmann Europe does not see the pipes as needed as we do in NA so it has been more of an addtion to the line for NA customers.

I think IND is looking to package it in the future with the pipes.

IND?

Exactly right! Are you sure you're not employed by IND? I haven't seen you around the office lately.

Jimmer · 02-20-2009, 05:30 PM

Would there be any benefit to not using the stock pipes and changing to these when available? Would it change the sound at all (either outside or inside car)?

DevJ · 02-20-2009, 05:41 PM

No benefit besides not hacking off stock pipes

It will not sound different but its nice to have connecting pipes!

to Eisenmann for producing them!

sparkyg · 02-21-2009, 12:39 PM

Maybe a tiny improvement in pressure loss but prob splitting hairs. It is more for a nice complete exhaust kit and very high quality, perhaps better than stock

Ryan@IND · 02-23-2009, 11:41 PM

As I told you guys already.... this is amazing!

MTrizzy · 02-24-2009, 05:46 PM
