ZZPerformance now carries a full length downpipe for the Bonneville, LeSabre, Park Avenue, Riviera & Olds 88 LSS.

The OEM Bonneville downpipe is about 12" long and bolts to the front of the cat with 4 bolts. The factory cat-back exhaust includes the cat on the H-Body car. This is a weld or clamp in downpipe and ends right before the factory resonator.

Our high flow catalytic converters are EPA certified. If your state requires CARB compliance, these do not meet that CARB standard. Please contact customerservice@zzperformance.com if you have any questions.

We are currently offering $75 to $100 (depending on year) in store credit to purchase your stock catalytic converter back from you. If you're interested, take a photo of your stock downpipe and email it to Henry@zzperformance.com. We will provide prepaid shipping labels for domestic (U.S.) shipments.
