Hey everyone, have a quasi-update...so no luck so far with a few setups we've tried making...and the time invested so far is quite a lot...it's been a frustrating project to end up with a lot of scrap tubing in the junk pile lol. Just figured i'd check in and let everyone know this isn't dead yet...but it's not really any further along other than knowing what doesn't work so far.

You can still get CR750 replica exhausts from me via www.moonpie.co.uk if you want - they work out a bit more than the target $1000 but they are awesome kit....just in case you want to ease the pain a bit ;D

Well it was an interesting read getting my desires up for a good 4/4 exhaust but left me hanging....... Did you get it figured out Colin?

$2,500 shipped is a starting point, I guess!  Surely someone around here could produce it for less then that.

I remembered this thread: http://forums.sohc4.net/index.php/topic,89562.msg1003943.html#msg1003943
But the OP never seemed to complete his pipes and hasn't been around here for a few years.

I tried bending some thin wall tube with my hossfeld bender. No go, it needs the inside mandrel. It will bend up a funny car chassis though.
