Show original supplier description
The ZZP 3" Regal Catback Exhaust is a premium, single 3-inch cat-back system engineered for durability and performance. Constructed entirely from stainless steel, this exhaust is built to last indefinitely. The 3-inch piping offers improved exhaust flow compared to stock systems. Special notes for installation: This is a true 3-inch cat-back system and will not directly bolt up to the factory 2 3/8" outlet downpipe. A 3" exit flange downpipe is required for proper fitment. ZZPerformance offers a compatible downpipe that bolts directly to this cat-back. Ensure you select the 3" exit flange downpipe when ordering. Important compatibility information: This cat-back exhaust will NOT fit if you are purchasing the ZZP stage 2 kit, as that kit includes a downpipe designed for the stock exhaust. This cat-back requires a separate 3" exit downpipe. If you have questions regarding fitment or compatibility, please contact customservice@zzperformance.com. Fits: 1997-2004 Buick Regal 3.8L.
