Looking for a new exhaust system for M3, I would need your guys' advice.
I'm looking at Meisterschaft GT2, Gintani sport, kreissieg, innotech,
I'm looking for a loudest and best sound level, power gain makes no difference to me, not quite into Kreissieg because of the price, just checked innotech and found out it was a valvetronic one just like the Kreissieg
However, whether valvetronic or not is fine for me, I just want the best and loudest sound available, probably with muffler only.
any other suggestions are also welcome, Thanks!
