GL1000 Exhaust interchange

Postby mrknox » Sun Oct 11, 2009 12:00 pm



If anyone could help me it would be much appreciated. I have looked everywere for an exhaust interchange for my 1977 GL1000 with no luck. I would like to know what years will pretty much bolt on without major modifications. Your help is much appreciated. Thank you.

HI
I also have a question about GL 1000 exhaust: Can I install exhaust from GL 1100 or GL 1200 in Gl 1000 (from 1978) without any modify?

I know the 1100 and 1200 exhausts are not even interchangeable, so I kind of doubt they will fit a 1000 without modification.

The header pipes from the 1100 will fit the 1000. The ones from the 1200 might, but haven't got a set to try.
Any muffler from any bike that has a one and seven eights inch inner diameter will fit the headers. Just have to press the old mufflers off, if they are clamped on. If welded on, that is a different story and some one else will have to tell you how to do it.

I have just 36 inch long straight pipes on mine, but I like them kinda loud anyway. Doing a search for baffle inserts and you may be able to come up with quieter exhaust by adding them.

The 1200 ones definitely don't fit.

The later 1000 ones will but have a slight kick up at the silencer end, so either use the whole 78-79 system or, as has already been said, the Harley ones look good. They are very well made but real heavy.

The 1100 ones are very similar to the late 1000 and will match up to the heads. Don'r know about the silencers though.

Motad make a stainless steel system for both 1000 and 1100. Expensive!

I have changed mine from the 3 foot straight pipes to a pair of like new mufflers from a KZ440. I mounted the headers and bolted the mufflers on the mounts under the rear pegs. The mufflers are the same 1 3/4 OD as the headers. I measured from the shoulder ring on the header to the beginning of the flare on the muffler and then cut two pieces of left over pipe from my straight pipes and put that all together. Looks fairly decent and sound is not bad either. My straight pipes would not clear my vetter bags, and these will.
