H-Body Downpipe


18 reviews

This product is currently out of stock.

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.

Hbody downpipe

Gave my bonneville ssei a very nice deep exhaust note. I would buy it all over again. Only complaint is its throwing a catalytic converter code so my check engine light is on.

Quality work

I have seen some other reviews about not having an O2 ****, mine did come with it. And the car sounds so much better. It was an easy install, and also has much better flow. Love the zzp team and products

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.
