My custom made stainless exhaust manifolds for the M70 V12

One reason why i wanted to get these one-off exhaust manifolds made is because i needed them and also, they’re a must-have!. It’s a needed part purely because the stock ones just won’t clear the Right hand drive steering shaft.
It’s a tough job trying to make these stainless steel manifolds. lotsa clearance issues especially where the flange will bolt the downpipes and the downpipes themselves. Pre-emptive thinking and precise measurements were made so the downpipes could go through in between starter and front subframe and lower arms.
Manifolds done. Now, it’s the exhaust that needs some serious thinking. The fuel tank is a turn off. A big tank right at the bottom of the spare wheel well just right for single muffler. I don’t have time to wait for more fabrication which i’d love to for a twin muffler rear exhaust. For that, i have to remove the sprare wheel well, and then either elevate the fuel tank or make one within the spare wheel well itself and scrap the stock fuel tank.
What i’ve decided for now is that i’ll just use my current AC Schnitzer exhaust while replacing the existing pipes meant for a 2.5 with bigger ones to make it breath better. I’ve always loved the sound it makes and i think it will sound awesome with the V12 going through it.
The future will see a full titanium exhaust exiting twin rear mufflers!
