Also running factory Classic Roadsters sidepipes behind a 351W. Nobody ragging me about quiet sidepipes, but they are rather mellow.

However some of the club guys have been telling me that factory CR pipes are fairly restrictive. 40 - 50 hp loss useing them? I can feel it when I'm in 3rd gear getting on it. Feels like it's holding back. I do have an extra set of uncoated sidepipes I could section, and put the new mufflers in.

Can you feel the power output difference with these things?
