I'm running a Vetterman 4 into 4 exhaust on my 7's XP IO-360. I get quite high CHTs because I think the four pipes fill up too much space in the cowl's exit. Anyone out there run the same system?
I've got the 4-pipe and I've thought the same thing. Although I can't say for sure that's the issue because there's probably more work I can do to seal up the baffles.
I'm usually bouncing off 380 or so, and on hot days my climb is limited to 110mph.

Have you always run the 4 pipe on this airplane? There's a member here who switched from the Vet crossover to the 4 pipe and saw no change in CHT. Perhaps he'll chime in, but I suspect the "blocked exit" is a bit of an OWT.
