OK, I had a TREValation today...
I crawled under the SSE to look and measure (whatta concept).
The part # I was looking at is WAY TOO LONG.
I didn't realize the exhaust system snaked around under there to the degree it does.
What I found was an area directly behind the CAT, and one on the right side more to the rear, that would accomodate the insertion of a glasspack of shorter dimensions.
Both of these areas have what appears to be a heat shield above them.
The behind the CAT idea doesn't look too good. Plus, it'* right under my ***.
The area further back on the right side looks correct, but, the muffler can only be 18" long- MAX.
Even then, it will be right at the bend in the pipe. So be it.
The part # from Cherry Bomb is 87510, which is 2 1/4" inlet/outlet/core diameter.
When I went to the store that had the other part on hold, they also had the above part.
Comparing the two, the only difference between them was that the 2 1/2" inlet/outlet is flared up from 2 1/4". The inside looked identical. The major difference was the length.
I switched out for the shorter one and will have to talk the 'muffler guy' into squeezing it into the limited length of pipe by cutting off the ends, much as he did when installing the ANSA tips. It'll be tight and I KNOW he'* gonna roll his eyes when I show up with this unit!
Another side note is that the dual resonator tips have the exhaust flow showing up on the outside of the tips more than the inside ones. I don't know if there'* a way to redirect the flow now that they're already installed, short of zapping in a little baffle, which probably won't be practical or possible.
I checked the Thrush/DynoMax site and they don't have a unit that fits this application, even though the glasspack is of the perforated vs. louvered design.
That'* the update on the mission to use the Cherry Bomb perforated core glasspack as a resonator. Is this just totally obsessive, or what?
