Latest update; emailed Borla and got a response back already!! Although they weren't 100% positive that the pipes were theirs, they said that CF sleeves are not available and that the pipes cannot be taken apart due to a special compund used to seal the muffler together...
Looking at their website, and comparing the internals of the car exhausts to my exhausts, they sure look the same. ( 4 individual perforated tubes stacked 2 x 2 and a larger tube around those )
I'm going to investigate any other suggestions offered up so don't stop now.
Ric - It appears from the photos that I've found thus far, the Giacamoto's have rivet's but I'm still looking.
Corse955 - After seeing the price on the Termi system I have to agree. I'm already planning on raising the back, have a Ohlins rear shock, but since I can't take it out to test on the track, I'm a bit hesitant to take it all the way up just to get ground clearance. I like your idea of taking some length out of the lateral portion of the header. I had intended to go with an ARC setup this winter but my lawn tractor died and I had to buy a new one so there went the money for that little project.
If anyone knows of a source for CF tubes I'd be interested. I figure I can cut the old CF and rivet the new CF tubes on.
