e90 m3 type mufflers for e34

[E34TURBO]

hey guys . firstly to introduce myself im from india and i have a e34 520i and iam getting a 525i engine transplanted into it with a turbo along . the exhaust would be a straight pipe exhaust and i wanted a muffler which is like in the e90 m3's i.e in which the distance between the two tips is lesser than the normal cars ,is there any muffler like that available or would i have to get the exhaust split into two .
cheers
