GS550 Header pipes on a GS550E?

[Ironhead]

Hi folks,
Can anyone tell me whether 81 GS550 pipes will fit on a 80 GS550E?
I've done a thread search but not found any definitive answers.
Thanks

The header pipes will bolt up to the engine fine but the rear muffler mounts changed in 1981; on early bikes the mounts are on the bottom of the mufflers but in 1981 Suzuki changed the mounts to bolt on the top of the mufflers.

You can go to the fishe and look up the differences for yourself... http://www.alpha-sports.com/suzuki_parts.htm

It may be possible to modify your frame to accommodated the new style mufflers, but the frame loop at the back will have to be cut and new mounts fabricated.

Fantastic,thank you.To be honest i'm not bothered about the mufflers as they're going on a custom frame and will be modified accordingly.
