I thought the FRPP sounded like sh_t. I was surprised that the MAC sounded as deep as it did--for me it was that or the Bassani. I was glad I watched the video before paying attention to the key of which is which--I think I was more objective that way. I have a Bassani exhaust that I have grown to like, but it can get old as it is a bit too loud (god did I really say that? Geez, I am getting old...).
Honestly? The silver Cobra sounded the best at idle and part throttle. The black Cobra sounded best at moderate to WOT. The orange Cobra sounded like ass the whole time.
Your not alone dude. I tell everyone wanting a loud ear drum busting noise to go Bassani! It took me a while to get used to it also. I will say I get a non stop rush of people asking me about my exhaust system. Thats probaly the only reason I haven't traded it off for something a little quiter.
