Hi, all!

Can anyone give me the pros and cons
of single vs. dual Gibson cat back exhausts?
I know I want one. Just not sure which.

Thanks!

Hey Nukeboot,

I have a related question. I, too, have been trying to get info on Gibson exhaust systems.
My question is, will the Gibson Dual Sport system go on without relocating the spare or modifying hangers?

I have a 2000 x-cab, 4WD, ORP, with P265x70R17 wheels and tires. The spare is the same size.

Has anyone installed the Dual Sport system on a similar truck? Any prob's? The retailers all say no problem, but I would like to hear from a few people who have actually done the installation.

 

i've already order my Gibson Dual Sport, and I'm just waiting for delivery..

hopefully in the next week or so..

I'll let you know how the installation goes..

MODS TO COME:

• Gibson Dual Sport Truck Exhaust
• A.R.E. LSII Hard Tonneau Cover

 

go to http://www.gibsonperformance.com

They will have all the info on each one. Basically, the SS is quiet, but more torque. DS is louder, but you will lose some low end torque.

Hope that helps.

MitchF150....Where on the Gibson web site does it state there is a loss of torque with the Dual Sport Truck exhaust? Maybe my reading skills are diminishing because the only statements I find from Gibson are boasting both horsepower and torque increases.

Sorry about that Zach. I must be the one whos reading skills and memory cells are diminishing. I could have sworn that I read that on their site..... I did so much "research" on the subject a month ago, that I'm really confused now.... I also read "hundreds" of posts on the subject and that must have been where I heard about the lose of low end torque for the duals. You get the increase in HP and torque with all the duals when the revs on the engine are in the upper end.

I personally was only interested in the low end increase because I don't need to break any speed records. I just want to tow and haul stuff... Needed it quiet in the cab too... but wanted just a tad more rumble...

If anyone else out there can "refreash" my memory on where I might have gotten this info, that would be great. I'm pretty sure that only the low end torque is effected (affected??) by the duals (< 2000 rpm's). Over that, I'm sure the duals gain it all back and then some, plus sound better too.

Nukeboot, Gibson has four different catback systems. The Sweptside, Dual Sport, Split Rear, and the Supertruck. The Sweptside and Dual Sport are the only ones recommended for towing, because they both exit out the side, behind the rear left tire. The Split Rear and Supertruck are not recommended because of the unpleasant resonance. The Dual Sport is the only one that is a SI/DO from Gibson that is recommended for towing. I just thought I would let you know

So, now the question is refined...

What are the pros and cons of the
Side Swept vs. the Dual Sports?

 

Yeah.... The reason I went with the SS was because of their claim for the "Increase in performance and towing power." Didn't even consider the Dual Sport Truck, because of this whole "loss of low end with any dual system". I'm not quoting anything, that's just the general impression I got from Gibson and the majority of posts.

Looking closer at Gibson's site now, the DS has the same claim as the SS, it's just not in BOLD type and not linked to the performance chart....... I don't remember seeing that before, but probably because I wasn't looking either...... I don't know. I got what I got and I'm still happy with it. Maybe next time....

Thanks, nukeboot for saying "Regardless of the loss of low end torque (which I also
saw somewhere on their site)". Makes me believe I really didn't imagine the whole thing...

Now we're heading for home.

I just noticed another difference between
the SS and the DS. The Intallation Skill
Level on the SS is "Beginner" (me, also
once known as "fumbles") and the level on
the DS is "Intermediate".

Methinks the winner is the SS.

 

er, installation that is...

 

I've got other posts regarding the actual install. Basically, I started to do it myself, but didn't have the proper tools and lost my interest in doing it real fast and had a muffler shop do it. You will need a sawsall at the minimum to get the old system off. Then a welder would be nice to have too. Those clamps are pretty ugly on the tail pipe. Actually, the adapter that came with the kit to put in the 3" inlet side of the muffler to connect to the stock 2.5" pipe, was too big. No clamp in the world would have been able to get it tight. So I would have had to take it in to get welded anyway.

Good luck.

Hmmmm. Welding near gas tanks under
my truck? Sounds like emergency room
stuff to me. Might just have to call
my mechanic for a price.

 

nukeboot,

Just take a piece of plywood and place it between where you are welding and your gas tank and you will be just fine. Don't pay someone to do your welding if you can do it yourself. I have welded mine after off-roading withough any problems, and all I used was card board once.

 

Found this on the Gibson web site. Regardless of the loss of low end torque (which I also
saw somewhere on their site), I plan to
tow a boat AND I have a cap so the Side
Swept single it is!

Why are the SPLIT REAR and SUPER TRUCK systems Not Recommended for Towing?

SPLIT REAR • Carbon Monoxide danger with any REAR EXIT system. Dangerous and deadly exhaust fumes, including carbon monoxide gas may be drawn into the rear compartment of Sport Utility vehicles, vans, or pickups with camper shells.

SPLIT REAR and SUPER TRUCK • During heavy duty towing both systems produce a resonance in the cab. Additionally, the Split Rear exhaust is directed at the tow trailer, and you may find exhuast soot on the towed trailer.
