Jk exhaust

[southernscouse]

Got a very good deal on a ss complete exhaust for my Gipsy been running a speed shop one for several years but as I now have another engine I wanted to be able to use a full size filter
What’s people’s thoughts on the jk unit it came with a band style of support for the long silencer as I had lost mine when fitting the speedshop kit just want check I am doing the right thing. Thanks Tom

Sorry Tom, I think the JK system is a pile of cheapo junk. Poor quality, bad leaky joints, horrible to fit, cheap mild steel U clamps, carp silencer. On one I saw the baffles broke loose inside and the wadding collected at the outlet blocking the flow. Customer chucked it in the bin for a new Speedshop system and was delighted with the improvement!

Thanks for the reply Andrew the reason I want to t are off the the speedshop exhaust besides the filter problem is that is fitted with mild steel flanges which now are leaking
One thought I did have was to cut off the flanges and sleeve it with ss pipe

[southernscouse]

Should have also said that the flanges to the heads are okay it’s the ones to the silencer pipes that are rusted

I understand this is a known issue on older Speedshop exhausts, and was addressed on later version with stainless flanges. Best to check before purchase though.
