I definately recommend the single swept side setup for this application. It performs the best in low to mid range condition of the Gibson setups available. It will increase the exterior volume of the engien with only slight increase in interior noise. Most of teh time it is barely noticable inside. The dual split rear is the loudest they make and I notice very little change inside, while my friends have made multiple comments on the increases low frequency outside. This is on a 2000 Dakota R/T with the 5.9L. That set up is designed more for custom truck applications adn racing being that it provides more top end performance than the other styles.

Hope this helps some.

Ryan,
I have a 98 4.2. I am very interested in the supertruck exhaust. With my having the 6 cylinder, I can't afford to lose torque on the bottom end. What should I expect if I have this installed? I like the look of the supertruck, would it be better to have an exhaust shop custom build the exhaust to look like the supertruck but with a muffler that wouldn't decrease my low end? Thanks for your help.

Sorry, guys, but I have had severe bad luck w/ my Gibson. Check other postings bout Side Swept systems to hear my story. If you decide to go Gibson, I wish you better luck than I Had.

I think for now, I'll stick w/ Flowmaster.

I've got a question on the dual sport. I have a 98 SC 5.4 that I installed this setup on almost 2 weeks ago. I am happy with the power increase and sound at idle, but it does drone in the cab too much between 1800 and 2100 rpm. This makes 65 on the highway very loud. Any suggestions? How much difference would the single exit system make? I might consider changing to that system.

Thanks

RED Y2K SPORT....did you notice a difference when you had the Gibson Swept Side installed?

I am really looking hard at buying the Gibson swept side for my SuperCrew 4x4 and was wondering if you had any feedback for us future Gibson Swept Side buyers?

 

Yes, the Swept Side is specificaly engineered for towing, more low end torque, better performance, and mileage got a little better also. A friend of mine put one on his Super Duty V-10 and got the same results.

 

No drone here with teh Swept Side I really like it.

Let me first apologies for my tardiness..

I have been stuck on Maui and away from my computer for the last several days taking care of day job crisis.

As for the Supertruck on a 4.2, it won't really decrease towing power, or bottom end torque, which ever you prefer to call it. But it won't increase it either. It is not so much the muffler though that determines the torque increase as teh pipe outlet design. Free flowing pipes produce more top end naturally by relieving back pressure. The trick is to relieve back pressure, but maintain enough at low rpm to get an increase. This is precisely what the single side swept was designed to do. I have had great luck with it on other vehicles I have installed it on, with very little interior noise. One other draw back to dual out fre flow pipes is the more flow, the more sound. I am running the dual split rear on my 5.9L R/T and in side at 1800 - 2100 it makes a drone, but not much worse than it was stock, however I have ben told that outside, ecsepcially behind me it is very loud though very deep and throaty so people I deal with and hang out with like it. The R/T naturally had a rough grumble to it stock though. But the basic Gibson line up is Single Swept.. most torque.. least noise, Dual Sport more noise, more midrange.. Dual split.. most noise.. most top end. The Supertruck seems to land in between the dual sport, and split rear. It is naturally going to make noise thanks to short pipes and large exhaust gas volume moving through it.

I hope this didn't make things more confusing.

Thanks for the feedback RED!!

Looking forward to installing one on my 4.6L this Fall.

Enjoy!

Rcv- could you be able to compare a gibson muffler with stock pipes to a flowmaster 40 seriers Delta? Cause i got that right now and its reminicent of a ricer one the 4.2 on the outside and gives a drone on the inside. I am looking to virtually bring back the truck to the stock exhaust sound and the inside while leaving the free flowing muffler on, possibly giving a throaty sound outside, not the buzzing iim getting now.

application for application every Gibson I have dealt with has been quieter than a FlowMaster with a deeper throatier tone. They are starting to make ricer sytstems as well that are deeper sounding than the standard bumble exhaust you here. The pipes them selves will help dampen the volume slightly due to turbulence in the bends from crush bent pipes. But you may or may not notice it. The Gibsons are a mellower toned muffler though. Single outlet is your best bet for the least amount of resonance and exterior volume.

Also, we found on a Dodge Dakota that used the FlowMaster delta serious with a V6 that the larger the can itself, the better off you are at dampening the ricer sound. He ended up using a big block muffler to tone down his lil 3.9L V6 enough to give it the deeper throat he wanted and deaden the rasp.

Any other questions feel free to ask, or email me directly.

Sincerely,
