Thinking about dual exhausts, 02 Trep ES 3.5l. Tips?

Hi everyone, new here on the forums. I'm currently running a 2002 Dodge Intrepid ES 3.5l and I'm thinking about replacing the single exhaust with a dual set up. My goal here is largely to improve the sound of that great V6 engine, something to make it a little bassier, rumblier, and more aggressive, and to make the startup sound a bit less, well, anemic.

Any performance gains would also be nice, although reading through others' posts suggests that there isn't much to be gained. I'm still a bit iffy as to what degree running duals on the Intrepid would work to reduce backpressure, improve fuel economy, increase HP, or anything like that. At any rate, I'm not expecting much.

Now I'm afraid I must confess my noobishness, because I'm not entirely certain what components go into running a dual exhaust. I wouldn't install it myself, would probably have a local muffler shop take care of it, but I assume I could probably save some money sourcing the components myself. If you guys could help me put together a list of components, I would greatly appreciate it. So far, I've found what looks to be a decent tubing kit on eBay. 2.5" diameter and Mandrel bends. Does this look like a good place to start?

(Sorry, can't posts URL's yet. What I've found is the TrueBendz tubing kit for 98-04 Intrepids. Google search 1st result for "98-04 DODGE INTREPID DUAL EXHAUST TUBING KIT")

I've gathered that I'll also need mufflers and tips. Any recommendations?

Thanks in advance for any help and advice. Love the community so far, you guys are doing some amazing stuff with these wonderful cars.

I have the stainless single to dual kit from TruBendz on my car and it sounds and looks great. It can easily be installed or you can have someone do it for you. A local guy charged me $50 to install mine.

Personally, I think the dual outlets are over-blown. My exhaust sounds just fine with a single out, it's all a matter of what muffler you use and what resonator arrangement you have. I've got a FlowMaster 40 and deleted the rear resonator. No muss, no fuss that way.

I did some other stuff up front for a little extra HP but it's not for everybody.

I did a custom axleback single on my 02 R/T, taking out 2 of the 3 mufflers and adding an 18" glasspack. I love the sound, nice throaty tone that's not too loud. It's enough to make people look as you accelerate and hear easily from the inside, but muffled enough so it's not completely ridiculous. If you're looking for a deep, aggressive tone, glasspacks are the way to go

As for the performance part of your setup, think of it this way: Anything you put in the way of the exhaust gases leaving your vehicle cause back-pressure and force your engine to work harder. Mufflers, catalytic converters, bends in the piping (even mandrel bends), rusted piping, incorrect diameter piping (too narrow/too wide), all these things restrict the gasses from leaving your car efficiently. You are required by law to have catalytic converters, and it is a good idea to have a muffler or two cause you can get pulled over and ticketed if a cop thinks your car is too loud (totally subjective). The straighter and smoother the system, the better. But you can find performance cats and mufflers everywhere that will pass emissions and also increase HP from stock. Popular brands are Magnaflow, Borla, Dynomax, Flowmaster... (just to name a few)

I had the trubendz single exhaust (flowmaster), sounds nice. i went up to a flowmaster 80 with dual outlets, not much of a sound difference but i love the look of the dual outlets.

Im thinking with the Magnaflow. But it could always change. And i like the look of dual pipes, was a truck guy my whole life. This is almost that system. What i like is that its not super ricey.
