During my recent beach trip I had the opportunity to hear a M3 with M Performance exhaust and it sounded very good. It had a very nice rumble to it with a sweet nite to it while not being too obnoxious.
While I loved it, I am looking for something a bit more aggressive. For those of you that have heard various exhausts including the M Performance... What systems are quieter than the M Performance so I can go ahead and eliminate those from my long list of choices.
Honestly I like the Gitani the best because sounds absolutely raw and mean, but I am afraid that it might just be a bit too much. What would be in between the M Performance and Gitani that would be awesome sounding with a deep rumble with zero rasp. I can live with a little but drone and I will be getting a full system and not just the cat/axel back.
Any thoughts and advice would be greatly appreciated!!!
