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.

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.

High quality and amazing sound

I finally had my LNF catted dp installed along with factory resonator and custom straight piping. Fitment was spot on. Quality of the dp is amazing. Very nice looking welding and finish. The sounds is Perfect! Very deep tone with little to no rasp. Loud when you get on the throttle and quiet when you need to be. Slight drone on highway with my set up but nothing super annoying. I am very satisfied with my build here. Thank you zzp!

Dual exhaust

So I bought a downpipe with no cat and angled oxygen sensor and it works perfect and looks great. Then for my California smog I bought the downpipe with cat and it passed with flying colors. So now I have an extra downpipe. But well worth it because any cat pipe here in California is $900 so the $270 I spent to pass smog was worth it....

Great part at a great price as always ZZP

Perfect figment as with every ZZP part. Catted pipe works with b1s2 O2 sensor just fine, no p0420 codes or other issues. Perfect, thanks ZZP
