The Y-design that you see in the ad is a revised rear design. The SCA exhaust does not come with the forward "Y-pipe". You'll have to purchase the SHOshop unit if you want one. I have the SCA exhaust, as well as the SHOshop y-pipe with the hi-flow cat (older design, which isn't "modular"). I had to tone the rasp down that was created with the Y-pipe by putting in a glasspack muffler to act as a resonator. I love the way it sounds now!
