311 Bravo exhaust setup
 

Did the 311 have a standard Bravo exhaust setup or was the exhaust used custom made? I am trying to ind headers and want to be sure that I need a bravo tailpipe. Can anyone that has changed the exhaust on a 311 with Bravos help?

311 is NOT standard Bravo Setup ......m

Was it a custom made setup and what will I need to replace the existing exhaust?

Did you talk to the header manufacturer? They will tell you the measurements you need to build your headers to fit to your specs.
I ordered a new set of Stainless Marine exhaust this year for my trs setup, and they fit perfect. Get accurate measurements... BC
By the way, nice 311

I did talk to CMI and I need to take a bunch of measurements and send them in to them, they do not know what I need until I send in the measurement sheet.

Just a guess - Std Bravo +3" extra height.

Can the exhaust exit holes in the transom be moved to accomodate a std. bravo setup? What's the reason for the extra 3"? Just for the Silent Thunder platform?
