After driving my 93 5.0l for a few months now, I've noticed a couple things. It gets terrible gas mileage (12hwy), is pretty slow, and the only noise I can hear is the intake sucking in air. I think exhaust could help me here. I should get a small boost in performance, hopefully better mileage, and will actually be able to hear my engine, which I like because I like shifting by sound, and enjoy the feedback I get from stepping on the gas.

Does this sound reasonable? Really, I am just looking for an excuse to do something to my truck!

 

go with a streight pipe, thats what I did on my truck, it sounds great, and I got a performance gain too.

 

you just cut apart the stock exhaust and put the straight pipe in there?

 

go true dual

 

duals take alot of fab work, or are very expensive to have done on these trucks, I would love to have duals, but I dont got the 400 something to get some built, but I am thinking about building some myself.

 

do a single pipe from the Y, into a Flowmaster Delta 10 with dual side exits. great rumble and sound in the cab so you can hear the shift and it performs really well.

The Delta 10 is a custom muffler and not all shops have them just fyi. thats the setup i have on my truck with the 5.8L and im running 3" pipe back and the exits are 2.5 duals before the rear tire right behind the passenger door. i can post exhaust clips if you want to hear it.

 

I've got a shop around here that will do dual exhaust for about $250, check around for prices. They don't have to fabricate much of anything. They had pipes on the shelf for my LeMans, they're just generic shapes with extra length on the ends to fit many different vehicles and they pick the ones that fit the truck the best.

 

You might have a clogged cat. If you can get away with it, eliminate the cat altogether, or use a high-flow cat with a performance muffler, like FlowMaster or Magnaflow.

A 2-into-1 single muffler works just fine on these trucks, will actually give you a bit more torque than true duals, and it's a LOT cheaper.

You can use the stock head pipes, with a 2-into-1 FlowMaster scavenging Y-pipe, 2-1/2" inlets with a 3" collector.

Use a 3" single-inlet, 2-1/2" dual-outlet muffler if you want the dual tips. You can run dumps under the truck in front of the rear axle (loudest inside), out the side in front of the passenger rear wheel (quieter inside than dumps, but still fairly loud), behind the rear wheel or the typical out the back under the bumper (quietest inside, but still loud outside).

 

I <3 my true duals with no cats. Only way to go, IMO

 

One of the local muffler shops suggested that I cut off the exhaust where the "Y" pipe joins and replace everything back with at least a 3" pipe and muffler. Your choice if you use one single 3" tailpipe or dual 2.25"-2.5" tailpipes.
