Our downpipes are made from stainless steel. No worries about rusting or paint flaking off. It costs 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 manufacture. 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, ask for a close up picture of their weld. You'll know right away, what true quality is and what it isn't.

The stock pipe narrows down to a 2" hole before flowing into the cat. This is very restrictive causing KR and a loss of HP. Our 2.5" stainless bolt in downpipe remove all of the stock downpipe restrictions. No more 2" inlet, no more O2 bung dimple. By doing so gains of over 15HP can be had along with a substantial drop in KR. Most users can drop a pulley size after adding our downpipe. Plus our 2.5" bolt in mates to the stock or 2.5" cat back exhaust system without any welding.
Transmission: This determines if you need a downpipe for an automatic or manual transmission.

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.

Nice quality product

I really like the quality of the 2.5" down pipe for my Chevy HHR. Would definitely buy from them again. Fast easy install and delivery. Didn't come with gaskets. Wished they would be linked with the down pipe for a more complete order.

2.5” downpipe

It is truly a unique piece to any cobalt SS, more power and a better piping of done with a 2.5” exhaust system. But overall I’m impressed with this down pipe!
