Cam,
I had the exhaust built at Fran's shop - they did a fabulous job. The "mufflers" are actually resonators. I'll find the part numbers for them and the tips and post them here. We played with various combination of mufflers, and found that the resonators fit perfectly. I have photos of the exhaust as it came from the shop, and better shots of them mounted on my website. Slc.postach.io - take a look in the portion labeled "SLC 010..." Around Aug 13 or so. This site is my detailed notes of everything I've done on my car, so way more info than you'd probably want
