This product is made to bolt in to your stock set up reusing your factory bolts and gaskets. If you do need replacement gaskets, they can be found here:
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 their weld. You'll know right away what true quality is and what it isn't.
Catalytic Converter Option: This determines if your downpipe will come with a catalytic converter or not. The 200 cell cat comes with an angled o2 bung so it should not set a CEL. We have a high metal 400 cell cat that will not set any CEL lights, and there is an 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. Off-road -You will need PCM programming to remove the 137-141 & 420 codes. They are not legal for use on public roads. They provide maximum HP gains and minimum weight.
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.

LNF Downpipe
Very good quality, was packaged very well, after installation it was a very noticeable difference with the 3 inch LNF catback exhaust that was installed as well. Feels like a whole new different car!
Quality craftsmanship and materials for a good price
The construction is textbook on the LNF 3" dp w/ 400-cell catalyst except the downward angle of the rear O2 sensor, but I don't see a better solution. No exhaust smell. Getting the nuts off the stock dp was difficult, but possible. Exhaust volume increased significantly with the ZZP DP and ZFR6758 with the stock cat-back.
2009 HHR SS
I got the catless off-road with the angled 02 sensor...downpipe is gorgeous installed in about an hour on lift. Pretty straight forward fitment is great....car sounds amazing now.
Awesome product
Gives the car a nice unique sound
