This fits on all Cobalt/Ion/G5/HHR/Pursuit models with the 2.0L supercharged, 2.2, & 2.4L naturally aspirated cars. Will not fit '08+ turbocharged models.

Includes:

    • Stainless flex
    • Stainless flanges
    • Stainless Spun metal cat (if selected)
    • Stainless piping

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, and the choice to come with or without a catalytic converter. 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.

How to order your downpipe:

Transmission: This determines if you need a downpipe for an automatic or manual transmission.
Catalytic Converter Option: This determines if your downpipe will come with a catalytic converter or not. We have a high metal 400 cell cat that will not set any CEL lights, and we have a California specific cat that comes with a Certification paper. There is the Off-road option which does not come with a cat, but it is NOT legal for street use. The Off-road option comes with an o2 bung for your rear o2 sensor.

Cat Coupon

ZZPerformance will give out a $50 coupon code for returning your stock downpipe to ZZP for catalytic converter recycling. You don't even have to pay for return shipping! Simply email a picture of your cat to Henry@ZZPerformance.com and if it is OEM we will email you a UPS prepaid return label. Then put your old downpipe (or just the cat) in the package that the new one came in and drop it off at any UPS shipper (excluding the catback box due to being oversized). Then we'll email you a coupon code good for $50 off of your next ZZP purchase! Returned units can be cut up but the OEM converter must be intact. Already bought our downpipe? We'll still offer the $50 coupon code but you'll have to pay for the return shipping.

Note: We can only issue prepaid shipping labels to people in the lower 48 states, this excludes Canada, Hawaii, and Alaska.

High Quality

Does what it's supposed to do. Welds are extremely well done, bolts right up to oem manifold or shorty headers like I have on my 07 cobalt.

Definitely a noticeable difference in throttle response I also bought the 2.5in catback and the strut brace zzp parts are worth every penny if you have to change a part on your cobalt or hhr replace it with zzp parts instead of oem
