I have to agree loud straight pipes belong on a river rig. If you want a clean good looking truck it needs good deep sounding exhaust. But this is my opinion and that means nothing to a handful around the world.

that's 6 Inchs of pipe. 3 inch is really only good for a si/so one these trucks. Genrally 2.5 inch is recommend for a si/so or si/do. 2.25 inch is perfect for true dual being that your actually lossing back pressure going true dials cause they flow so much better. If you are going for strictly sound then what the hell go 3 inch true dual, but your perforce is gonna suffer.

He we go again.....this problem would be easily solved if some one would come out with a H and X hybrid pipe some thing like this ( |X| ). Anyways I truthfully don't know what one is better, I frequently read exhaust threads and my opinion changes all the time. To many "dyno sheets" on this thread contradict each other. But that's for a whole nother thread I'm pretty sure the OP isn't gonna go true duals

With good mufflers IMO 3" is perfect. Back pressure is a totally not need for performance. Look up back pressure myth on this site and read what they say. Back pressure helps low end the more pressure the better the low end will be. The more free flowing and the better the top end will be. And the better it will sound. Win win in my book but it's all a personal preference.

3 inch true duals is way to much In my opinion. I have read the myth thread many times and I personally have my own therorys (probably completly wrong but o well). Anyways why would you want a better top end, its a truck how much time do you spend in your high end? Most guys want a strong low end for towing and daily driving. If we where talking about muscle cars this would be a completly different story being that they spend more time In the top end.

A true Dual exhaust actually reduces back pressure. That's why most guys go with a 2.25 in pipe (2.5 is stock) to get some off that back pressure back. I wouldn't worry to much about back pressure kit you are just doing a muffler swap. just stay with 2.5 inch pipe, that will make it easier anyways. Any "perforce" (flowmaster 40s, magnaflows, borlas, ext) will normally reduce back pressure, but its not enough to worry about, it might actualitily be helpful.

Don't put the flowmaster on!!! Unless you like the head piecing drone that comes with it. I did I straight swap with a magnaflow maganapack, it has a nice deep rubble at idle, it sounds loud and strong with acceleration, and you cant even tell its there when cruising. There's no headaces with straits through mufflers, unlike chambered ones like flowmasters. Straight throughs sound smoother to me also, most of the flowmasters I have heard sound hollow. Do some research on you tube and look at 18 or 14 inch magnaflow mufflers, the 4x14 magnapack, the xr1, or dynomax bullets. Everyone is gonna tell you to stay away from the magnapack, xr1, and bullets cause they will say its to loud bit most of those people have high flow cats. If you keep your stock cats and go with any of the mufflers its not gonna be to loud. I have stock cats and just cut out the stock muffler and put a magnapack in its place and used the same tail pipe, but if you into the no tailpipe look then just put a dump after the muffler.
