Which exhaust is the quietest while being the most efficient?
I want to upgrade, but do not want more noise.
I was thinking a custom exhaust with a big truck muffler, 5" in and 5" out about 54" long and 9" diameter.
Not sure the noise reduction would be as good a factory, but the flow is way better.
Thanks

Magnaflow seems to offer the quietest solution. The Walker BTM that I have is one of the noiser ones, but it really isn't that bad. Personally, I'd go with the Banks system. $660 for 4" from the turbo to tailpipe. I haven't done it yet, but that's the next mod.

OnEdit: I forgot to mention that it's a completely stainless system.
Deib,
I had the Walker BTM. It lowered my egt about 50* - 75* when I had otherwise stock exhaust. But it had a flutter I could hear in my echo. I got the Jardine 4" with a 3 1/2" down pipe and the Magnaflow. I love it's low mellow tone, nice rumble, not too noisy.
