hey there. i've a full Supersprint exhaust with cat made for the E30 318is. But it has no sound, only the engine. I want to have some decent low sound, but i decided not to take out the cat, coz it's originally maded, and it will only crap this nice exhaust.
So i'm looking for some sport air filters (K&N, Green,....), and here is the deal.
To go with a filter in to the original airbox (http://www.knfilters.com/search/product.aspx?Prod=33-2059 - this is made for the IS)
Or to check something universal like this (http://www.knfilters.com/universal/universal.htm).
I think the uni is not the best way, so if there is a good quality open air filter made for the 318IS, just show me.
