I did just the two long perforated pipes, and the car sounds really nice, you can hear a bit when cruising, and when you step on it, it sounds sweet.... Very loud!
Based on this, I wouldn't replace all pipes, just the two long baffles! my 2 cents! |

Is it safe to say test-pipes + ACM exhaust mod for a daily driver might be a little much? I like loud cars, but a E90 M3 shouldn't sound like a nascar IMO. All the sound clips sound raspy, but it seems like the motor isn't warmed up. I want the performance of test pipes, with the sound of the ACM exhaust (only). Guess you can't have your cake and eat it too.

I don't see where the rasp comes in if everything is stock and just doing the ACM mod. The rasp comes from removing resonators... The ACM mod is not raspy by itself compared to if you did the mod and resonator less. But people have differently tolerances to what is raspy and what isn't.

Agreed.
I was referring to adding test pipes. ACM by itself should sound perfect (no rasp). I had a WS6 with cutouts a long time ago (similar to straight pipes) no rasp at all. Quote:

I've replaced two perforated pipes with solid, removed centre cat/resonator with solid pipe.
It's mega loud and fairly raspy above 3000rpm. I mean VERY loud. But I think I like it. From way too quiet oem to maybe a bit too much? I don't know, I keep smiling. |

So IMHO, Test pipes + OEM exhaust mod = no Test pipes + other exhaust (I think I'm going to go with Megan exhaust) = yes. But I'm happy with the way my exhaust sounds, so I'm in no rush to chop everything off and start over.

sorry to open an old forum, but I was wondering what you did with the pipe that goes through the center of the mufflers. |

The middle pipes remain untouched with the straight thru (outter) method. There is also the version that just the center pipes are modified, which is a bit quieter.
