Exhaust (Un)Install

[yegg]

OK,

I started replacing my headers last night. I stopped because too many beers later I said the hell with it. I did get my old exhaust system removed. Now tonight I get to put it back together. But I have a few questions.

Starting setup: Stock headers with 3800 miles on them and CFR slip ons with 2900 miles on them.
1. Why the hell was it so easy to take off the left slip on and the right one made me teach neighbors new word combinations?
2. Can someone please take a picture of the socket they use for the front cylinder bottom flange nut? I have a hinged driver attachment but that was of no use at all.
3. Before installing the heat shields, do I need to thoroughly wipe down the bare head pipes like I do on the heat shields prior to starting the bike?
4. And just to double check, do the studs for the flange nuts get thread locking compound or anti seize compound?

Thanks.

Anti seize on exhaust hardware, a good isopropyl (alcohol ) cleaning on tins and other pipes to remove any residual grease before heating up the exhaust.

Ok, any tips for a slip on that won't slip on? One went on easy and the other I am still fighting with. As it is, I can barely get it on a 1/8" and I have at least an inch to go. The guy just won't budge.

The ends of the exhaust can slotted 180 degress out, for compression. Is it possible to spread them apart slightly

A little penetrating oil on the end of the header pipe allows muffler to slide on easy. Also open the ends of the slip on slightly with vise grips.

I use a 1/2" crow's foot wrench to remove and torque the front lower exhaust nut. As for the slip fit connections, I use antiseize on the interior and exterior of the pipes. This will help them go together and come apart more easily.

I used a tail pipe expander to spread the pipe on my Supertrapp muffler.
Opened it up maybe 1/32, it fell on.

Clamp tightened everything back up.

I used a tail pipe expander to spread the pipe on my Supertrapp muffler.

This is how to do it. Also, the head pipe may be out of round. Squeeze it back round at the opening with a big pair of channel lock pliers. Protect the pipe with something so you don't gouge it.

Ok, got the right muffler on. Ok, I lied. My friend did. Turns out I was way too timid. But, I did try an expander first. And I tried some lubricant too. He came over, tried it on the old header and it went on no problem. He had me hold the bike as he really leaned into it with a bit of wiggling too and it just popped on. Buttoning things up now. Hoping to beat the rain so I can fire it up and hear it. I wanted to post here first as everyone has been so helpful.

Remember, you have to get that muffler back off to change the rear tire.

Guess I need to start working out again.

I installed some chrome acorn nuts on top of the header flange bolts once I installed the header. They look good and once torqued down (same spec as header flange bolts), I don't have to worry about the header bolts coming off. I thought I had read here to never use any compound (anti- seize, Lok-Tite, etc.) on the header flange bolts so I didn't. Also, I added a bit of Permatex Anti-Seize when I installed my Rinehart slip-ons- should make it easier to remove when/if I have to in the future.
