Hi everyone,

I have a E46 M3 Smg11, I have just orded the supersprint cat replacement pipe, and the silencer replacement pipe, has anyone done this yet?I have left the standard backbox on as I like the tinny noise, do you think by replaceing these pipes it will get louder?

I also want to chip the ecu, has anyone done this to thier cars and if so what chip did they use?

Thanks.

M3,

while this is an M3 forum..and johan does have alot of info to provide, i would suggest checking out www.m3forum.net

your pipes will make the Raspy Tin noise louder....also many people have chipped their cars. Most use the Shark Injector or eurobahn's software

Hi,

Since we have covered this topic many times in this forum I would strongly suggest that you use the search menu option (It's very useful).
