Hi
Im doing that conversion now and wondering if m52b28 exhaust pipes will fit my s54? Found a reall good deal on one so willing to buy if that should fit. Thanks!
S54 ports are round with 3 bolts; M52 ports are oval with 4 bolts. Headers are also different lengths. The rest of the M52 exhaust is 50mm while S54 is 60mm and the sections do not interchange.
If this is holding you up, this swap will be challenging for you.
