H-Body Downpipe

SKU: ZZ-BONDP3-X

$169.99 Sale price

Catalytic Converter Option
Regular price $169.99

ZZPerformance now carries a full length downpipe for the Bonneville, Park Avenue, Riviera & Olds 88 LSS.

The OEM Bonneville downpipe is about 12" long and bolts to the front of the cat with 4 bolts. The factory cat-back exhaust includes the cat on the H-Body car. This is a weld or clamp in downpipe and ends right before the factory resonator.
This downpipe can be ordered with or without a cat and is one piece.   

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.

To take advantage send to:

ZZPerformance
Attn: Cat Credit (Order #)
2450 28th ST SW
Wyoming MI 49519

For everyone: Include your original order # and email address to send the coupon code. Write down your return tracking number for your records!

Worked great

I opted for the down pipe with the cat. Everything fit great. I was pretty surprised actual. Very well built. I also bought the clamp with it and it made it an easy install.

Work of art

Installed this on my 96 Bonneville. Had to change my exhaust manifold to a 97+ for it to connect properly. After that short ordeal, it fit right up with my stock exhaust and 02 sensor fit right into place. This piece is built like a work of art and flows and sounds great. Highly recommended purchase for your 3800.

Modification required

Rear o2 **** not equipped on the pipe as pictured. Pipe reducer on the end not compatible with existing exhaust. 4" needed to be removed to allow for fitment to existing exhaust size as well as o2 **** location. Was able to make it work with minor modification but may be difficult for someone without fabrication equipment.
