No, different exhaust. Please stay tuned for details tonight (too many things, too little time). The new exhaust, the GT Lightweight is a parallel-exit style exhaust that has one of the better exhaust notes I've heard for street cars along with weight savings that are near Titanium levels. There is nothing "more advanced" with the ARC Titanium exhausts other than a very strong metal is used which results in thinner walls and less mass. I'm not saying one is better than the other, just providing additional information.
Here are two ARC sound clips:

We're working on providing a spreadsheet that overviews the features of the exhausts we sell to better aid customers in deciding what is best for them.
Some manufactures provide dB ratings (if you read, the Fujitsubo exhaust page actually has the dB ratings). However, we feel that different manufactures measure in different ways, leading to different results.
The only accurate way to get consistent data would be to test each and every exhaust, which is not possible. As a compromise, we have decided to use a subjective rating scale based on what our "tuned" ears tell us.
As a side note, we received a new shipment of the JGTC Parallel exhausts. Please phone 877-863-4520 and ask for Chris or Ryan if you'd like some more info.
Cheers,
