916 spider 3l12v
Dear fellow alfisti, I am looking for new downpipes for my 12 valve 3 litre spider. Since I have to change them might as well try equal length. 24 valve is easy but are there any off the shelf options for the 12 valve? Or is custom built the only alternative? Probably has been discussed before but could not find definitive answers. Any comments will be appreciated. Thanks!
