New Exhaust help
With much effort, I finally removed the stock exhaust system from my 2010 FatBoy. When installing a 2:1 aftermarket system (in general) is there a helpful tip (besides Scotch) in making installation easier?
For example, is it better to try to line up the front or rear pipe first into the cylinders? Both at the same time? So far, both pipes are over the studs, but I am having difficulty in getting the flanges far enough over the studs to bolt them securely, and there seems to be a gap behind the flange. I have only mounted on nut loosely on one flange, and I am resisting the urge to start banging away.
Incidentally, my brand new HD service manual omitted several steps of the system removal, and references the wrong page to see specifics on the oxygen sensors! Please help! Thanks!!!

the flanges will not sit flush with the head, so don't try to torque them down until they do, otherwise you'll be asking how to extract a broken stud next. follow the manual when you are tightening the nuts, and don't overtorque. ( i like to use anti-seize on the threads, but some folks will tell you not to ). make sure everything is started before you tighten anything down, that'll give you the play necessary to make minute adjustments before you snug everything up. just take it slow and easy, don't try to overthink it, and before you know it you will be done.
just resist the urge to fire it up until after you've cleaned your pipes, otherwise, the oil and grease from your hands will get burnt into the chrome.
and after you've ridden a couple hundred miles, check them exhaust nuts again, they have a tendency to loosen up.....

+1 on Skratch...
I just finished my 2 into 1 installation in the Heritage Softail Classic.
What a pain in the a$$ for what should have been a simple installation. I had removed the stock system before so those issue you found in the manual were not a problem for me cause I had them before.
My new exhaust was 5/16ths of an inch to long. WTF SupperTrapp???
A half hour with a cutting tool and now it fits.
Front and rear exhaust ports wiggled into place and I torqued each flange nut evenly, crossed my fingers and not leaks.

I would/should think most all new pipes have installation directions...
I would follow read through them first before starting,, maybe several times..
I've only done my slip-ons and they were a breeze.. didn't mess with the headers.
So install papers and a shop manual should get U through this one.

Rant! --- Sorry
The directions were great, the reality was not. The parts made the directions impossible.
Yes yes yes this is something anyone with basic skills should have been able to accomplish.
My 2 into 2 SuperTrapp is perfect now that I cut 3/8 of an inch off of the header so that the muffler would slip on far enough. (WTF SUPERTRAPP still waiting for a call back for their customer service department).
You must have the resources at hand, or available, to successfully compete the project.
Look folks these bikes are basically very powerful lawn mower engines in a fat heavy stable frame. So why can't the the motor company and 3rd party suppliers make parts that just fit and can be installed by people with basic mechanical skills? Oh I know why our designers are lazy ****'s and our products are supported by incompetents.
This stuff should just bolt together.
