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 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 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!
