Ok, I put on my jba headers and I like them. Not spectacular gains, but some and a 1-2 mpg gain. Now, for the next part and my apologies because I'm sure many questions like this have been asked before. I want an exhaust for my dakota with a dual outlet look. I'd REALLY like a dual outlet so I need good suggestions here. I don not know of any cat-backs that'll clear my 4x4 yet. My dakota's a 4x4 4.7 5 speed club cab with 3.55 lsd. I want as little resonance as possible inside the cab with a slight to modest gain outside. I really do not want to lose any performance and would really like to gain some from a cat-back or custom setup and would like it to clear the spare tire (full size 16 inch). Do you know of any cat-backs out there to meet my needs (or as close to it as possible) or should I go with a custom job from a muffler shop? If you recommend the custom setup what would your recommend?....1 or 2 Mufflers and type, tubing size, etc. Sorry for being long winded and thanks in advance

I started a topic based on this a few days ago..
look at gibson or flowmaster 50 series...
gibson is more expensive but stainless steel,
and flowmaster is cheaper.. but made from
normal steel.
gibson has dual split rear or single side out,
unfortunatly, you must remove the spare for
dual out.
as for flowmaster, you would want to get the
SUV series 50.

I ended having a custom setup done so I could keep the spare in its current location.

See guys I have the MBRP dual rear split and the spare tire still fits and gibson is not stainless,MBRP is more expensive but it is true stainless steal but I went for the aluminized system,MBRP is not cheap but I compared them all with my eyes and it was the most well made,perfect mandrel bends,nice welds,nice heavy guage metal and it fits perfect,its gota count for something,you get what you pay for also gibson,mopar and K&N exhaust is all the same

Thanks guys for the advice. Art, how would you compare the interior noise level when having a conversation or listen to music at a normal level? Also, how much did it cost and where did you get it from? Thanks

They have a website its www.mbrp.com it cost me 700 canadian,I can take some pics and show ya when I get a chance,I got mine at a local performance shop that had all the systems so it was nice to compare the quality,if you dont tow or need a bumper they have this sweet lookin cuda style rear split,I got the under the bumper one need to tow once in awhile,noise wise it was real shocking when I first hooked it up :)its a nice low rumble at idle and screams when you get on it,when your cruisin you can hear it but its just right in my opinion,later

It is a dual offset muffler. 2 1/2 in and out (according to Flowmaster tech I talked to the other day) However if you buy their Cat back kit, which you can get from Summit for $199 it comes with a dual offset SUV 50 series muffler 2 1/2 in and 3 out. Bolt in install that you can do yourself. All mandrel bent pipe too. They claim a 10% hp increase.

hey art I would like to see pics of your exhaust and see how the shop did your dual shotgun exhaust while keeping the spare. Pls post pics of the underside of the truck showing the pipes and spare if you can thanx. Well I guess this goes for anyone else that has a similar setup with spare still in. I am running Magnaflo which is a great muffler. Anyone know of the dates that DC began to put three cats in the truck?

I have a 50 series Delta Flow (not the 50 series SUV one) Flowmaster single in dual out and kept my spare. Had it custom done. $234 tax tag and title. Not loud in the cab at all but really nice outside. Sings good when getting on the gas.
DC started with the 3 cats in the 2000 trucks. I only have 1 but know lots of guys with 2000's that have 3.

mbbank, I thought I would just correct your above post.
Gibson is more expensive and is aluminized steel. They do have an even more expensive system that is stainless steel.
Flowmaster is not normal steel. It is aluminized steel just like the Gibson. They don't offer a stainless steel version. If you live where they use a lot of salt on the roads stainless steel will be worth it. I live in Texas and there is NO salt on the roads. I have never seen a good aluminized exhaust sytem rust in Texas.
You are correct on Gibson offering split rear and having to remove the spare tire.
I don't know about the MBRP system but on Gibson and Flowmaster you will see a larger gain with a single 3" pipe.
The Flowmaster cat back for the 4.7 is a Force II. It uses a normal 50 series muffler. It is not as loud as a 40 series and it sounds great. The main difference between the normal 50 series and the SUV 50 series is case size. If you want a quieter 50 series get a delta flow.

According to Flowmaster the Cat back for the 4.7 Dakota is an SUV 50 series muffler. I was told this on Friday when I called them. The catback kit is #17278. The muffler in the kit is a modified version of #52558 The modification being a 3" out instead of 2 1/2.

Yes, Tommithy you are right. I looked at it again and it is a tad larger than my normal 50 series on my Jeep. Thanks for the correction. I will say that if you are considering the Flowmaster cat back, go for it. I love mine. I am thinking about replacing the 50 series muffler with a 40 series but that will be later in the future.

I have a 50 Series Delta Flow and Viper has a 40 Series Delta. The 40 isnt any louder than the 50 it just has a throatier sound. The 50 is a bit deeper and more mellow. Just got a 40 on our Durango. Same thing. All the Delta Flow does is cut down on the interior resonance. Still the same sound outside.
