I've read all of the posts in this forum on exhaust modifications. I'm leaving headers out of this discussion (for the moment). It seems most are really wanting more sound out of their 968 with the HOPE they can have a little extra power across the RPM range without a sacrifice somewhere. The conclusion seems to me, no matter how odd the OEM exhaust configuration appears, Porsche perfected it so well that any different setup has resulted in a sacrifice somewhere in the RMP range.
According to the discussions, it seems the RS Barn Catback was the only system that came close to delivering. But, RS Barn is gone now. Billy Boat seems to be the second favorite. However, the BB website claims increases over stock HP numbers but the Dyno numbers presented are obviously not from a 968. I personally spoke with Mr. Boat a few weeks ago and he was unaware of the numbers on his website and said he had no idea where they came from and that if there ever were any supporting Dyno information for his 968 catback, it had long been lost.
What all of these aftermarket systems do seem to provide is a change in sound and a weight reduction if you can live with the possible performance shortcomings.
So, back to the perfection of the original configuration. Cargraphic makes a system which maintains Porsche's original configuration, delivers more sound (two versions), saves weight and, like the others, claims HP and TQ gains. The system was developed and homologated for the N-GT racing class. There is hardly any mention of this Cargraphic system on this forum and I'm wondering why. Perhaps it is the cost? It is expensive, but given it is the only system that starts with the original design Porsche seemingly perfected for the 968, just maybe it delivers on something the others have fallen short on?
Does anyone have any personal experience with the Cargraphic catback? What am I missing here (cost aside)?
The system is "modular" so you can get everything from the headers back (or just catback), or just certain pieces as direct bolt-on for OEM pieces. Here is the link:
