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 $250 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.

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!

Way Better then stock!!

Would have been a peice of cake if all of my bolts that connect the downpipe to the catback were completely rusted so I had to cut and drill them out after that went in in 10 minutes if that love the turbo sound!! I have stock catback with muffler delete and it sounds great!!! Fits perfect and sounds great plus got $150 in store credit for stock downpipe!! Thanks zzp for awsome products and customer support!!!
