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.

Our downpipes come with a high flow catalytic converter that is 48 state legal. Our catalytic converters will not pass California or New York state emissions. Please contact customerservice@zzperformance.com if you have any questions.

We are currently offering $200 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.

Replacement for factory part

Replaced failed factory part with this and save a ton of money. Works great, had a CEL on for a day that went away after evap and o2 monitors reset.

Nice piece

This went on a '09 HHR SS manual. It was installed with ZZP's complete 3" pipes and muffler (resonator delete). I can't comment on the downpipe alone, but the system as a whole is great so far.

Phenomenal downpipe

This downpipe was easy to install and is phenomenal. I don't feel any additional power, but now my Cobalt has some more thunder in the higher rpms. Really makes it sound like a turbo 4. I highly suggest this upgrade!
