Like everybody else am looking to putt som more power and sound into my car, so I have been looking at Supersprint cat-back system, it was quite a bitt expensive in my country ( $2500 ) from mitt exhost demper.
I have purchased a K&n filter but in resurts i found out that this dosent give enny more power =(

What kaind of exhaust is requmanded ? does eisenmann give more power or only sound ?
 
exhaust and air intake wouldn't give you more than 5bhp more at a most I'd say
maybe 10bhp at an absolute push...
 
Thx !

You might wonder then why I did not buy bmw z4 35is but 23i
the reason is that there are about 90,000 exstra cost (fees and tax to the government)

23i is around $ 71,000 (used) and the 35is is around 135,000 (used)

But still are there enny simple things to do that gives more power ?
 
I've no real idea on options for the e89, but check out mstyle's collection of e89 stuff here: http://www.mstyle.co.uk/acatalog/BMW_Z_Series_Z4_Z4M_E89.html
 
Thx

I find this exhost the best on the market ( estimatet on the sound )
