More info

Our downpipes are made from stainless steel. No worries about rusting or paint flaking off. The cost is a little more but we feel it's worth it. All welding is done to the strictest of standards and bears a professional finish. Weld quality is higher than any other downpipe manufacturer. We promise our welds to be 100% leak free. Even the flanges are stainless, which isn't something most companies can say. When shopping around, ask if the downpipe is 100% stainless, and ask for a close up shot of the weld. You'll know right away what true quality is and what it isn't.

We are currently offering $75 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.
