Rich, Lean, WTF
I just pulled my J-Pipe to install the shorty water box when it comes and I found this on the exhaust manifold, carbon buildup on the pipe and a grey/shiney substance on the flange. This is after about 10 hours of running with my gutted and shortened stock water box with jpipe cut 1" and flared for 1". My waterbox appeared to have been a little hot where the jpipe enters because the black rubber cover looks like it melted under the rubber clamp for about 2". Just wonder if this is something to worry about or just regular maintenance? Jpipe did not look damaged at all.

the grey shiny substance is aluminum... tahts' the bell of your exhaust manifold that couldn't take the heat. ur either lean or on the rev limiter

What Shibby said ... and contact Steve Friebe and exchange your manifold for one of his modified ones that he installs a SS bell on, or else you run the risk of overheating the flex joint in your J pipe and having that leak eventually ...
Interesting picture ... the 'bell' from the end of your manifold melted off and it seems like there was a little exhaust reversion that then deposited the superhot aluminum backwards onto the flange.

Vern... i just smoked my manifold running the rev limiter for about 20 minutes... same thing on my ski... it went backwards and embeeded itself in the same spot

if all the mods in your signature are still up to date, and 70.7 is your top speed... well that's why your speed is so slow for all those mods you have listed... you have few more mph in there once you get the rpms down... you should definitely be moving along faster with all those mods you have larry
