Who makes the best downpipe?

[matt5112]

Right now its $100 coupon...

I was just there and it was $50 to send the cat in, unless they have it somewhere else. Either way, I really don't need anything else from ZZP. I need to get cash back in my account

EDIT: Copied straight from ZZP

For a limited time ZZPerformance will be giving out $50 coupon codes for returning your stock downpipe to ZZP for catalytic converter recycling. You don't even have to pay for return shipping! Simply select "prepaid return label" from the drop down and we'll send you a return shipping label with your purchase. Then put your old downpipe (or just the cat) in the package that the new one comes in and drop it off at any UPS shipper(excluding the catback box due to being oversized). 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.
