is there any advantages or disadvantages to having my duals both come out in front of rear pass side tire? now they are coming angled out back, might go with a new look eventually. will the exhaust do anything to my polished rims? change sound any?. thanks
yes it will change the sound, no it wont hurt your rims, the only advantage/disadvantage is change of sound, different look, and dissadvantage is you might hurt them faster, i.e dirt, rocks, and tar

True duals? If so, the only disadvantage I can think of is the amount of bends involved in routing two pipes to in front of the same tire. Lots of bends is is not a good thing for flow. Using all mandrel bends helps, but it also gets spendy and complicated.
Why not y-pipe it down to a single 2.5 inch pipe? Unless you have a stroked 5.4 and/or forced induction, a 2.5 single should work well.

Y pipes are a bad idea, they take your power away

True. The best thing to do with a Y pipe exhaust is have a new Y pipe mandrel bent real fine to elliminate the restriction, and have it go into a 3" intermediate pipe, then into a 3" muffler with dual 2.5" outlets. Keeps everything balanced well and helps scavenging.
Unless you have forced induction or a built engine, 2.5" true duals are not going to net you more low end torque than a y-pipe will. There is a reason all fullsize trucks come from the factory with a y-pipe design....
To the OP: no advantages/disadvantages as far as performance. Just pick the look you like best and go with it.
lol.

Not ALL fullsize trucks, my buddy's GMC came stock with no Y pipe, just a single muffler, dual in, single out... But that's a GMC and what do they know anyway!
On the dyno @ Troyer's, the highest power came from a y-pipe with a si/so muffler and he recommends that system for a N/A truck without major modification.
In cold weather, the exhaust will mess up your wheels. The 97 F150s had the exhaust coming out in front of the wheels and in cold weather climates they ruined the wheels. There was a silent recall on the wheels because it was only a problem in the colder areas. I live in Minnesota and had a 97 that Ford replaced the wheel and relocated the exhaust pipe because of the issue.
Thats not at all true. A y-pipe, when properly designed, is a very good thing. Ever heard of 4-2-1 headers? Ever seen the results they produce? All they are is a header some y-pipes. The same thing applies to going from the headers/manifolds into a y pipe then into a single exhaust tail pipe. If everything is properly sized and properly engineered a y-pipe equiped exhaust system will be far superior. Exhaust is all about scavenging and thats what y-pipes are all about.

A dual in single out muffler is a y-pipe....it just happens to have a muffler in it.
To the GMC exhaust comments, if your guys are speaking of a 2500HD, 2000 - 2006 those trucks exhaust factory are 3" duals with hi flow like cats all OEM, and the whole system is 3" duals, the muffler is a 24" dual in/out then Y jointed running a 3.5" tailpipe. Why I am not sure but they are programmed factory like that and perform quite well. My Silverado 2500HD still got up & went with the stock exhaust, not so much after I did the true dual Super 44s though
Advantages are you can hear the exhaust better in the cab, even with a relatively quiet muffler, the disadvantages are the tips do take more abuse, mine cause a black haze on the lower rockers and that it is louder in the cab. I have had 6 different exhaust setups now, and the sideswept is my favorite sounding and looking, sidepipes for life And a y-pipe is the most effective exhaust on a small block that is lightly modified, but the factory Ford y-pipe is necked down ALOT, mine on my 98 measured less than 1 3/4" inside diameter. Run 2.5" duals, I have pictures of mine if you want to see, there is no need for mandrel bent either, the short run of pipe does not need mandrel bent, there won't be any performance gain for the extra $$$ you will have to spend.
