hi, I found a set of 2:2 supertrapp megaphone series for sale for an '84-'86 FXRS, that is the sales pitch. No product nr. given.

Would these fit my 1993 FXRS(SP)?

When I use the supertrap product finder, the search returns the same supertrapp productnumbers when entering model year (for your Harley) 1986 as when you enter model year 1993.

Unfortunately, I'n neither a HD-guru, nor a Supertrapp-guru,

can anyone shrd some light?

***correction***
pn = 4MSS-71340, can someone still shed some light?

Our current units, P/N 828-71335, fit '84-94 FXR's. The units in question were should work through to '94.

So the 4MSS-71340 unit should work? (just making sure you're talking about the same unit :-) -the only thing I'm concerned about if it fits the exhaust opening on the cilinders of the '93)

The head ports shouldn't be an issue...if there were an issue it would be with support mounting/brackets.

Good to hear :-)

Received the pipes today.

Is there any detailed manual available on how to mount this thing?
The I had hoped the manual had more (assembly) pictures.

I haven't got the stock exhaust to begin with, so following the (ultra) short 'manual' is confusing (plus I'm not a 100% familiar with the english mechanical terms).
I really feel like a noob here. Though I'm not unfamliliar with biks, my HD & Supertrapp knowledge is seriously lacking.

It looks like the support mountings on the pipes coming from the header converge around the clutch-cover (as if I should secure these by running my clutch cable through?)
