Single or Dual Exhaust??

[Rob Slade]

I am wanting to upgrade my stock exhaust. I have taken my spare tire from the underside of the truck and moved it up to my safari rack. This should give me room for a dual exhaust without a lot of trouble. I was just wondering everyone's thoughts on the advantages/disadvantages of a single vs. dual exhaust setup. Would the dual give me more horsepower, etc? Or would the single exhaust be enough. Please let me know of your experiences with either and which you guys think is the best. Thanks for the help.

to get the right back pressure from a dual system u would have to run super small piping of u run regular piping u will loose back pressure equaling torque loss i run a single and noticed at least 10 hp and maybe 15lb

Just run a dual out muffler like a Maxflow or Dynamax (spelling?). I went to a local high performance exhaust shop that specializes in custom exhausts. They put on a dual out with 2.25-inch pipes and 3-inch chrome tips and performance was actually improved. A certain level of backpressure is necessary for our motors to operate ate peak performance but stock, there is more backpressure then necessary. Go for it but ask the pros about what would be the best muffler to use. And when I say pros, I don’t me the guys at your local muffler shop. They know stock. Find a place that specializes in custom and/or high performance exhaust systems and get it done right.

rob, i noticed on your signature that you are from wake forest. we should get together sometime and go wheelin. i know some places to go here in raleigh, are there any good spots over there in wake forest?? you can email me about it, my adress is jjmattox@mindspring.com

You will probably be better off using a nice single cat back system with 2.5" piping.

I really don't understand why people think this. The size of the pipe and number of pipes you use can be irrelevant. Notice I said CAN. The fact of the matter is most of the backpressure (after the cat) should be controlled by the muffler. That's why I recommend going to a pro shop. If your cat and muffler produce the correct backpressure for what your using your vehicle for, the tail pipes serve little purpose other then looks and sound. Of course if you use a wide-open muffler, smaller pipes may be required. If you want dual exhaust, get dual exhaust. Just have it done correctly. There is no one way to do it. There is however a right and wrong way.

The PRO muffler shop that built my custom cat back advised me to0 go single exhaust and to use 2 .5 " piping.

I also checked with several other shops before having mine done' they all sa9id the same thing.

I am very happy with my system. There was an immediate seat of the britches power increase and a definate boost in gas mileage. Just what I wanted/

Definately, there are more ways than one with exhause systems.

Hey, I don't mean to imply that dual is better then single. Just if they are done correctly, it shouldn’t matter if you run dual or single. Rob appears to be interested in duels. I'm simply trying to guide him in this endeavor. Like I said before, seek the advice of professionals. If you have it done correctly, there is no performance advantages to doing it one way or the other. It is less expensive to go single out though. No custom bending required.

 

[aldive]

My single was completely custom bent.

Aldive, I think what Cameron meant was that a single out exhaust setup doesn't require any "engineering" to run the tailpipe. You do have a "custom" tube that wasn't in a kit, but all the pipe bender had to do was use the old tailpipe as a template for the new one. The driver-side tailpipe in a dual setup would be much harder to route and would take a lot longer to fab. Just wanted to clarify what I think Cam meant.

So in all, spending that extra $$$ money you will get the extra pipe on the driver side? Well but i looks good though
However, mechanically speaking, you can get the same performance using single exhaust by replacing the muffler, and/or pipe?

Thanks.

Pretty much yeah, you are paying for the look of dual exhaust. Thats how Shawn Gibson (from Gibson exaust) explained it to me when I asked why they don't offer dual systems. He said that you can get just as good if not better performance from a single, at less cost. Gibson is a performance company, not a show&shine company, so they don't see the need to sell duals fpr the X.

Now, if you really want the duel look for less $, you could go to a junkyard and find a driverside exit pipe, cut off about 3 feet of it so it ends behind the driverside tire, and buy some hangers. Then you have dual exaust look for $10 over single exaust's cost. Of course in the winter it will be pretty obvious...

LOL... hehehhe
