Hi Jon
I had a similar problem on a Europa supplied front pipe on my Classic a few
years back. Ended up replacing the standard exhaust with a stainless unit
---From CKT Aero & Automotive Engineering. Bought second hand from an owner who
was converting his Classic front end to XS.
Regards
Pete

Subject: Europa-List: XS Exhaust System Cracks
Hi, I'm suffering from exhaust cracks - specifically in both of the rear
cylinder downpipes on the inside of the tight bend. The cracks form around
the circumference of the bend and when first discovered were approx 75%
around each rear pipe! They are very hard to spot normally as the location
is right out of line of sight and well hidden. Each one has now cracked
twice, the first occasion I found them both cracked and had them welded up,
since then I've found them individually (just found the second one gone
again).
History - Fitted secondhand Rotax 912ULS last year (replacing the existing
Subaru) with a brand new Firewall Forward kit from Europa, including of
course the brand new exhaust, this kit I had purchased 2 years prior ready
for finding a Rotax engine. The first flight of this engine and new FWF set
up was June 2011 and has done 25 hours of flying total since then. The
cracks were first spotted after 15 hours of flying.
I am 100% confident that I have fitted the exhaust (each time!) carefully
and correctly with no strain or stress on any of the components. The engine
always extremely smoothly with no vibration.
I have just e-mailed the factory about it but was just wondering if anyone
else has suffered exhaust problems like this or can maybe offer advice?
Cheers, Jon
