Features:  100% Stainless Steel 2.5" Mandrel Bent Piping Chrome Rolled 3.5" tip Deep Tone This should be called something like cat and back because this "catback" exhaust includes the secondary cat section as well. 100% stainless construction, and is one more quality ZZPerformance manufactured products. Very, very good sound and very minimal drone. This will bolt up to your stock or ZZP mid pipe. For maximum gains and to completely replace your stock exhaust from the turbo back, we recommend adding the ZZP o2 housing and midpipe package. How to order your catback exhaust: Model Option: This determines what Sonic you have. Sedan means you have a trunk, Hatchback means you have a rear hatch instead, now the "RS" means you have a factory body kit that requires a specific tip. We only offer an "RS" specific model for the hatchback Sonic and there is no "muffler delete" option. We currently do not offer an "RS" model for the Sedan. Muffler Option: This determine what kind of catback rear section your catback will come with."With ZZP Muffler" Comes with our ZZP stainless muffler and a 3.5" chrome rolled tip. "Muffler Delete" Comes with a straight pipe in place of the muffler and the same 3.5" tip mentioned above. We HIGHLY recommend ordering your catback with the muffler option.The 1.4L turbo Sonic comes without a resonator because the turbo keeps the exhaust tone mellow. Fits 2012-Current models.
