You can get a better muffler that isn't loud if that is what's keeping you!

Like which one? I haven't seen a muffler that will produce noticable HP gains without increasing the noise level. Since having the sport model, i see that there are also 2 small resonated mufflers just b4 the tips as well.

Best bang for the buck on our exhausts seems to be replacing the Y-pipe and muffler. You could dump the exhaust if you like, but then there will be those two cutouts in your factory bumper where the tips were.
What is a good Y-pipe and where can I look at it online?

Magnuson does have one, but it's pricey. This truck has one: http://www.truckinweb.com/features/1...ram/index.html
