Thinking to get exhaust with valve like IPE, etc
Hey guys, I am new to M3. Does any aftermarket system adds hp or tq? It seems like it's all for sound. How about IPE or akrapovic? Will I loose torque if I open the valves? Can't find any dyno for it.
Thank you

i got the MRF full system mrfpower.com i gained roughly 28-30hp gains and the car sounds insane. It produces the most HP gains that i have seen so far. there are other systems with gains as well. Browse the exhaust section on the forum and you will find some great info. GL with your search!

I have the full IPE and love it.
I haven't put the car on a dyno yet just need to get a pulley and tune before I do....
