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.

ZZP “stage 1”

Ordered the catless downpipe, along side with the ZZP cold air intake. It completely transforms how the car sounds and feels. Exhaust consists of stock resonator and a cut off muffler, it is loud on acceleration and quite under regular driving. Very very happy with the quality and ease oh the parts.

AMAZING!

I'm VERY happy with my new LNF CATTED downpipe. I have an 09 with a catless one and the difference in performance is nothing I can tell. The positive side to a catted one is no nasty smell all the time. Thanks ZZP for another fantastic downpipe!

Catless downpipe

Thought it was gonna be too loud but i bit the bullet anyway. It sounds great all the way around. It does get a little louder on start up but once the car is warmed up its barely noticeable.
