This is a piece of 3" stainless tubing that is expanded to slip fit over another piece of 3" tubing. It is meant for someone that has a 3" downpipe that reduces down to 2.5" for the stock catback but wants to run a 3" catback. Cut a few inches off your 2.5" exit downpipe, slip this over the end, either weld it or use one of our stainless band clamps. It comes with a bracket for the factory exhaust hangers and an o2 bung.
You all know this part isn’t necessary, it could have been avoided with a full-size pipe and a universal ****** system. HOWEVER... like all the other stuff, it looks pretty good, and had it been sent with a clamp, installation would have been really easy as well. Rate 7 outta something, idk, it works.
Overall I think the company is great. Fast shipping, great prices, quality, and friendly customer service.
It works very well with the 3" SS 400 cell cat and 3" SS downpipe .
Over the past two years, I have been modifying my '99 Grand Prix GT with many ZZP parts, all of which have been of excellent quality. Now I am putting some finishing touches to this on going project, a ZZP cat back exhaust! Nice!
