Interested in any advice around replacement of at least the rear muffler on my 1982 GTV 2.0.  I need to change this to pass registration. When registered, the car will not be a daily drive. A number of people have suggested I look at a stainless steel custom build as the Alfa original $300 ex E.States will corrode quickly.
So, suggestions and experiences from those who have been down this path before are appreciated. I am aware of positive feedback for a place in Belmont from a forum post back in 2012 for a GTV6.
Thanks

Any *competent* exhaust shop should be able to do it. You don't really need stainless back there - a decent mild steel muffler wlll last a long time. Its a bit tight between the tank and the spare wheel well and the exhaust moves a bit with engine torque - don't put anything too big/wide in there - imho (I like some noise) a small hotdog is fine.

Is it just the muffler that is stuffed? The trickiest bit is the section of pipe that goes through the dedion triangle over the driveshaft passing near the brake calliper. Get this wrong and it will hit *something* under some conditions. This is where you need some competence from the exhaust shop... Note that buying a factory pipe doesn't actually ensure a perfect fit here (especially if the rest of the exhaust isn't all perfect/original but even then... A good shop can do better than factory.

Also - the exhaust on these cars needs to be dropped as part of regular (ish) tailshaft coupling (donut) maintenance. Do *not* let the shop weld up joints as a quick leak repair! Ideally get them to fit a proper flanged joint or flared for a v-band clamp at the front of the section I just mentioned to make removal and replacement easier.

I flaffed around with building an exhaust for my 83 GTV 2.0 for quite a while but could never stop it either touching the ground over any imperfections or touching the underside of the car or worse still, falling apart! I discovered the rear muffler rubber hanger was broken and couldn't find a replacement at Cilerberti's so tried a muffler shop around the corner. I showed him the broken rubber and he knew immediately that it was from an Alfa! So I decided to let him have a go with my whole exhaust.

Long story shorter, somehow he managed to give me a great sounding exhaust that never hits the car and has remarkable ground clearance. He also made it with a flange connection to assist with dis-assembly. After about 5 years the exhaust is still in great shape with no rust or signs of degradation and the price was very reasonable.

Don't suppose you have a note of the system parts or photos you can share?

Sadly no photos of the system off the car but I will get underneath the car in the next day or two and take a few snaps. I remember one of the mufflers is a lukey but don't remember the other. He also put a little hotdog in when he rebuilt my shambled attempt.
