So I got tired of cleaning off my rear brake arm and bought the Ryca exhaust adapter to see if I can get my Dyna muff to blow soot elsewhere.

When I receievd it I was a bit disappointed in the fact that the chrome plate was not the greatest (obvious where they hadn't buffed it out at the seam).

I contacted Ryca and they were kind enough to either replace it, refund me or take 25 bux off the price. I choose the last option figuring I can cover it with a heat shield and be done.

I removed the existing muffler and header and cut down the header the required amount to slide the adapter on but now it appears as though I need to bump the inside diameter of the muffler (btw, I have a couple different types) to allow it to slide over the adapter...it just needs a little bump out to slide over the adapter...

Even then the rear muffler bracket seems slightly off...just bend it to suit the new angle?

What have others done to accomplish this?
Sand the inside of the muffler to clear (Like maybe a flap wheel)?
Take it to a muffler shop and have them do it (at what cost?).
I've even thought I might get one of those loaner pipe expanders at the local AutoZone to see if that would work but they have pretty mixed reviews.

Any input is welcome...thx

If the muffler is used.....look and see if the slots are parallel - sometimes a previous clamping episode has squeezed the slots together.  You can open the slots back up a bit by inserting a screwdriver and prying/twisting.

Thanks for the input. I used the flapper wheel and also bent the tabs out a smidge...gently tapped the adapter into the muffler and then slathered the header end with exhaust sealant...no leaks!

Previously I had a DynaPower muffler on there and then went to a regular old Dyna takeoff.

I don't think any amount of wiggling the header/muffler/brake arm would have cleared before...my brake arm was always black until I cleaned it...then it would get black...then I'd clean it...you get the idea

I did notice that once the header end was cut down then the amount of play you can get w/o using the adapter allowed you to get a bit more wiggle room for adjusting the direction of the exhaust plume. I had the whole header loosened previously (w/o the adapter) but no amount of tinkering would get it to clear completely.

Thanks again for the advice!
