Re: Quietest free flowing muffer/exhaust system
I have put on both, except the MagnaFlow on an '94 5.8L van and on my brother's 5.4L Expedition, and my current V10 has Banks.
The Magnaflow was great, but I would worry about it on a V10. Banks did some serious work tuning the muffler to make the V10 sound like a big motor (It actually sounds like a Cummins under high-load, low RPM). Every other muffler I've heard on the V10 makes it sound like a loud Honda. Not like a fart can, just like somebody took a V6 Honda and turned up the volume. I wouldn't call it obnoxious, but it just doesn't sound right. That said.... I also have the PowerPack headers, and they may have played with the tube routing at the collectors to adjust the exhaust note.
