De Cat Mid Pipe

Post by RobVZ3 »

Hi All

Basicly im looking to buy a de cat mid pipe for the Z3.
This would be with a standard exhaust.
Has anyone else done this, if so..

Does it sound nice? I want some more sound but not horribly over raspy as im aware a de cat mid can potentially do this.
Is it louder? I dont want unbareably loud however as with the roof down it will be annoying as hell!
Any noticeable power diferences?

Cheers for the help guys!

I've heard an ///M with decat pipes and a sports exhaust, it was louder.

You could always swop over pipes for the MoT :wink:

I have a decat pipe on my 1.9
There is an irritating noise between 3000 and 4000 rpm. Probably some sort of resonator would kill it...
Apart from that it is fine..
