Default Score!

Quartzsite score!! Been looking for an exhaust system for the 87. Not sure how many more times it'll take welding. Walking around the swapmeet I found a guy with 3 complete systems. Two 09 and later, and an O2 sensor 08 and under with aftermarket mufflers. Bought the early system with all the heat shields and band clamps, for a decent price. Gotta get some gaskets and get it changed now.

Update: By p/n these came off an 06-08 CVO Ultra. The mufflers are stock HD with cats. Not sure how long the cats are, but they are right at the inlet, so easy to remove.

Not sure what they'll do to my tune? Probably WAY MORE restriction than the original aftermarket turn outs that were on it, and the original HD touring mufflers that are presently on it. I know it's running a little rich with these.

Nice Score.. I would leave them the way they are and do a ride and check new plugs before hacking..

In my research it showed that an 06 came with a 110" motor so it's very possible that that setup will be fine for your 96"er..

Ya think? I'm afraid that the cats will clog with a carb. I guess I can get them on and see how she runs.

These CVO mufflers are frickin HEAVY! Everything looks almost new.

I ordered the O2 plugs and some gaskets. Gunna change them as soon as the parts come in.
