Looking for Exhaust Options for XS 400RJ Seca 1982

[flutterball]

Need to get a new exhaust for my 1983 XS400RJ Seca, old one is all rusted through.

So far I have found this one : Mac 2-1 Part #004-1103 and it states it will fit the XJ-400 Seca and Maxim, will it also fit on my XS400RJ? It can be found on this page http://nichecyclesupply.com/ProductDesc.aspx?code=804-1103&type=0&eq=&key=it

Know the 1982 Seca xs400 is very different then the 1980 XS400, completely different engine, but what about the 1982 XS400RJ vs the 1982 XJ400 Seca? Would the exhaust header fit?

Any help would be appreciated, since once bought it cannot be returned.

Thanks In Advance.

how bad are they? if it's just the muff's that are rotted cut them off and weld up some new one's .mine where rotted and the down pipe's where all rusty and dinged up/cracked from the oil level peep sight and back so i cut them down and weled up some new pipe .

Thanks DTMF for the reply, was thinking of doing just that, but since I don't have a welder and needed extensions, plus the the pipes bent and then two new mufflers to weld on, it likely ended up being cheaper and less hassle just ordering the 2in1 MAC shown above (got a good price on it with free shipping), Know your making changes with your XS400R so will post some pictures of the changes/mods I've done on mine over the years soon (I've owned it for the past 20+ years),
