Things that work for the hemi will work for the v-6 as well. Just to a lesser amount. It is still an air pump, just like the hemi. More air in, more air out, more hp.

 

Thanks. I read something about the V6 needing more backpressure than the V8 (no idea if this is true). Is it possible that a high performance cat back--likely designed for the Hemi--reduce performance for the V6?

 

You really don't *need* back pressure, exhaust scavenging on the other hand is way way more important. Exhaust scavenging creates a bit of a suck that pulls the rest of the exhaust gasses out of the cylinder. That's what you want.

 

I'd love to get a better exhaust system for my V6, performance addition or not.. Mine has the singular tailpipe.. so I'd have to consider the cost of replacing the rear panel in addition to the exhaust system makeover..

 

Yeah, the dual exhaust should be standard!

 

I installed the Mopar CAI am am very satisfied with product. Great sound, especially when you punch it. The sound is subtle at lower RPMs, but growls when you step on it. But more importantly for me, is the mpg increase. 1-1.5 increase. About a 5-7% increase in mpg.

 

Great to hear about the mopar CAI. Have you made any other mods?

I just read diablo hasn't cracked the 2015 PCM yet... That was going to be my next question, lol. I guess CAI and exhaust it is.

 

Magnaflow makes a V6 system
Corsa and Borla will have to be modded
Personally I dont believe the Corsa has enough back pressure for the V6, they do need a little BP to build tq

Thanks Steve, will look into the Magnaflow. You think that's my best bet?

 

What do you think of this video of a Gibson axle back on a V6 durango:

IMO, sounds better than the Flowmaster cat back for a fraction of the cost!

 

My upgrade adventure is off to a great start. Reached out to my local dealer, provided them with the Mopar CAI part #, and asked how much installation would be. Their response back to me was... we're not sure what a CAI is, can you provide us with more info?

 

This is for the mopar cai. Btw, I've never had a single cai that I was uncomfortable installing. They're pretty simple with basic hand tools.

I did just a K&N filter because, I didn't know what I really wanted at the time and that alone was an improvement. I think I would do the Airaid to take advantage of the air duct under the hood

Well, you've clearly never met me, lol. I don't even own a wrench. I like the Mopar one because I understand it's pretty much maintenance free.

Just order it online and install it yourself

I have learned a lot about engines, catalyitic converters, resonators, etc., but I would never attempt to do anything automotive related. Plus, I really don't even have 90 minutes to spare with 3 children under 4 years old!

You should have just bought the Hemi... Lol, kidding. Doubt you've heard that before . I'm glad to see a topic all about the V6. I'd like to do a dual exhaust still. Put mods on the backburner for now, but a CAI is definitely next for me

I did think about it, but didn't pull the trigger for several reasons.
- R/Ts with a middle bench are hard to find up here in Canada and a bench was a must.
- Our gas is expensive (when I was looking it was around $1.2/litre, or $4.5+ a gallon).
- Our vehicles and taxes are higher in general. A fully loaded R/T would probably come in at around $65k.

I'm very happy with the V6. If I can spend under $1,500 to get a Mopar CAI, performance exhaust, and Diablo (when they break the 2015 PCM) and add about 20-40hp to bring it up to 325-345hp I'd be very happy!

Dealer got back to me, $130 to install.

 

Check out carid.com i got my wheels from there. Chraper than buying them where im from in canada. Next purchase will be cai, full exhaust n chip for the V6 engine. Will be more than $1500 but i should get some decent hp gains

 

I wouldn't call myself super handy, but I did the mirror tap without issue and I plan on installing mine myself. Ordered it last night on Amazon.

 

month old thread.. bringing it back to life...

to the OP.. did you decide on CAI yet?

I went with AFE and the Pro Dry filter and absolutely love it! HUGE improvement in sound from stock intake system and i fell it has a little more power (or maybe it just SOUNDS like it!! LOL)

but the pro dry filter never needs oil.. just a simply rinse and dry filter..

Ok.. looks great... and question:

Is the existing air intake tube just hollow? Even where the formed plastic is in molded boxes along the tube? Is there some purpose to that at all?

And since there's no hood scoop to pull air in from, is it still just pulling all its air from the vent in the grille?

The box where the filter is is open on top.. does that meet with the hood when its closed or is it drawing in hot air from the engine compartment?

Sorry to be so questiony.. learning..

 

Nice Clean fit
STEVE

 

Great stuff, caskey_b.

No, I have not installed the CAI yet. We had our third child and our dog passed away so it's been a bit hectic! I'm at 4,200km now so I'm going to have the dealer install the CAI when I take the D in for its 5,000km service. Should be within the month!

 

Does anyone think buying a V6 is just that? What do you need more performance for? Have you used the performance you have? Are you racing people off the line? It's a GIANT SUV.

You want performance?! Get the V8...Hemi baby!....CAI and cat back systems will give you marginal improvements. Like less than 10 HP. And real Cold Air Intakes, employ real cold air...Not an open filter in the engine compartment. More of a "ram air" system that has air coming from outside the engine compartment. I would encourage you to look up the difference.

me? I though I kinda explained that in post #25?

 

Being a v6 owner myself. Im of the opinion that i bought a v6 because i wasnt going to take advantage of the v8 and also gas prices where higher a year ago.
The v8 in my opinion was going to get me in trouble down the road.
With the Pentastar i have enough ponies and if i want to get a different sound then i add the cai, if i want more i just add the exhaust. And if i want to get more hp then i add a tuner.
Some may say its ridiculous to add a cai, exhaust and tuner to the Pentastar. But i say to each his own.
I had an 03 liberty renegade with the 3.7 v6 and i always felt it had potential the only problem was that i did not know where to start.
With my durango this time i am educating myself little by little. Eventhough i know that i will not be able to kick a hemis butt. At least i will try to give it a run for its money.

Also dont forget to add the family decal on your rear window to truly unlock the force inside the v6.:razz:

 

I've read posts from Pentastar LX owners that the Diablo tuner works well with some real gains.
That is most likely the best bang for your buck mod available.

These guys seems to have a pretty good rep and are up in your neck of the woods.

 

I just stumbled upon these guys, and did a search on the forum to see if anyone had any reviews. The idea of buying a DiabloSport InTune and getting a custom tune for the 3.6 sounds interesting. Anyone try this?

 

Alright, so I have a bit of a problem.

There's no way for me to get my hands on the Mopar CAI for less than $650 (plus $130 for installation). Dodge Canada will not budge on the price and I can't find a US store that will ship it to me for less than $60. In addition to the $60 shipping fee, I'd have to pay around $75 for the import duty.

A local shop here can do the K&N CAI for $340. Plus I can get a Gibson Axle Back system for $600. That's $940 for a CAI and an axle back vs. $650 for just the Mopar CAI. Or another way to look at it is I can get the K&N Filter plus an AIRAID throttle body spacer (does this thing do anything?) for less than the Mopar CAI.

Thoughts?

By the way, here's a Gibson axle back on V6:

 

Also: I can get an AIRAID CAI for same price. Should I get AIRAID or K&N? I prefer the looks of the AIRAID

 

Man that is steep for a CAI. Not sure if I ordered the damn thing and then shipped up to you if there would really be much of a savings? As far as K&N, someone else posted it was too loud for their taste. I think the Airraid and Mopar are pretty similar. As far at the Throttle bottle spacer, I read they were garbage.

 

I am very happy with my R/T exhaust on my 11 crew v6. I did a write up on it for all the single-pipe-to-dual-pipe conversions with part numbers and sound clips:

http://www.dodgedurango.net/forums/...e-durango-how-tos/18489-upgrading-single-v6-exhaust-r-t-duals-part-numbers.html

Also, for intake, I will have to get the Mopar kit, only because in CA it is the only one that is CARB legal, and I don't want to have to hassle with changing it out and storing the stock for emissions testing.

As for why I got the v6 and not the v8, it is because an equally equipped v8 in my area of CA was carrying a ~8-9k premium. I would have liked to have a v8 and would have paid a 2k premium, but the v6 is plenty of engine and I refuse to support dealer gouging.

I upgraded my exhaust for sound (any performance was just and added bonus), and will be adding CAI for the mpgs and every little bit helps (only getting ~13-14mpg with 95% city driving, again any performance is just an added bonus). A tuner (probably wont be) but might be added at a much later time for the same reason as the CAI
