They are using photo from other car's exhaust. The midpipe is not that long. Below is our Ti-cat back and Ti-midpipe. I don't think there is any US vendor that makes a Ti-midpipe except us.

Im a fan of HKS Ti exhaust. Not the carbon wrapped though because the piping is a bit smaller. Im pretty sure its 102mm piping with a 115mm tip. The carbon wrapped Ti is 75mm piping and a 120mm tip. Both have a very deep sound and I was surprised to find not very loud.

The Greddy is all titanium from front flange to back tip including mid hanger bar. Th muffler hanger clamp and bar is SS, but system still weights in less than the JIC. By the way Tip diameter is 114 mm ~4.5 inch., I did burn up my rear valance piece, need to bend can support bars to increase tip clearance.

18 to 22 roughly for a stainless cat-back. Depends on the model, size of the piping, thickness, muffler size.

Chuck,

It looks like a design change on your cat-back system from the early prototypes. The bends look mendral bent, not like the earlier model that had welds in the bends. I like the MP too.

greddy is a 1 piece cat-back. The picture must be from another model since the Greddy I got to dyno test is a 1 piece design.

Does titannium effect the sound? I have the old greddy PE and to be honest, it sounds like s**t.

Noise Levels?

Has anyone been able to hear how loud each of these are? I'm looking into getting a new exhaust but don't really want one that will wake up the neighbourhood when I go for one of my early morning drives on the weekend.
