I'm planning on purchasing a pair of RRP 2.5" electric cutouts with down tips. Does anyone know where the best location to install the valves? I'm looking for a "f1 style" sound when I hit the switch. I've seen videos of straight pipe M3 that sounds really good and other sounds too raspy. However I did run my car for a day without mufflers and the Z4M is different even though they both have the same motor (different pipe design).

I'm thinking either before my mufflers or between the headers and secondary cats. What do ya'll think?


Thanks, Kream
