I believe it's there 2.5" inch up pipe and silencer. More effective in higher horse applications than stock turbo. They have the prices listed on their online catalogue
These are definately the kind of quality you should expect! Amazing looking welds! The time that goes into making exhaust this pretty well worth the money.
I like the 3" I think I make a 3" for my sled now. The 2.5 seems small. . . HAHA.
