Back Box 118D

[BenG3284]

I've got a 118D Msport and i'm after making it louder, with current situations I can't afford a full exhaust system and I am wondering if I got a performance back box if it will make a difference?

Hi Ben....welcome to the Forum

An aftermarket back box would enhance the sound and slightly increase performance with gas flow.

Have you got a particular make in mind?

Cheers

I'm looking at any reasonable priced, would love to splash out on a full exhaust system but looking at reviews and prices miltek are way up there and I simply can't justify that money.

Any recommendations will be grateful

Cheers
