I recenlty had a Dynomax Superflow (part 17740) muffler installed on my 01 Pathfinder. I have done research on the web and this muffler offers an increase in exhaust flow with limited increase in noise. The stock muffler went from 2 - 2 inch input to 1 - 2.5 inch ouput. The Dynomax has 2 - 2.25 inch input and a whopping 3 inch output. I chose to continue with the 3 inch tail pipe with no resonator.
The results is a mellow deep rumble during acceleration. While cruising on a steady speed, the exhaust is barely noticable. I had done no pre-modification quantiative measures, time acceleration, etc. However, the truck seems more responsive.
Here are a few pics?
Here you can see the monster exhaust. No fancy tip yet, so it almost appears stock. Also, notice the Air Lift bags in my coil springs. I add a few pounds of air to them when I tow my boat to level the load.
Why would you dub this "Dynomax Project"? It's not like it's never been done before. I guess you don't live in the Bay Area, California, eh? Most every vehicle out there has a 3" exhaust and a Dynomax or Magnaflow or Raptor muffler setup with dual exhaust. Needless to say, I'm not that impressed even if you are. This is somewhat akin to buying a bag of jellybeans and holding them over the head of a rich kid with a bag in his back pocket. Hehehe.

I think it looks great. Dynomax Super Turbos are one of the best values on the market. You can get them through Jegs.com for less than 50 bucks usually and their flow rates are among the best out there. I'd love to see an independent test with flow rates of different brand mufflers for the same application and see which flows the best. Marketing don't mean nothing...let's see some numbers! But anyway, congratulations on the new exhaust. If you put a higher-flow intake system on, you will capitalize on the potential gains of your new muffler.

Well, I can "dub" the thread whatevery I choose. The title is not relative. I'm not trying to impress anyone, but share my mods with others. I have found Performance mods for 01+ Pathfinders are hard to find.
However, thanks for your response.
jadcock:
Thanks for the positive reply. I researched the web for the best muffler for the buck and thought this Dynomax model was ideal. I have been reseaching modifying the intake as you mentioned. I have not seen a CAI make for my model PF. I also have been reading about the 2 stage foam replacement filters, which drop into the stock filter box, but have not seen any solid info as to how effective they are.
Maybe 88pathoffroad can enlighten us.

Generally speaking, installing a higher-flowing muffler will benefit almost any motor vehicle, so that kind of mod on your Pathfinder is neither unheard of or hard to find. It's a generic power-adding mod that works for everybody.
Finding these took me about five minutes. Maybe you just need to look harder or use a different search engine.

I never said my mod was a one of a kind. This muffler was not made for the Pathfinder. It is actually for a V8 Camaro, but turning it around allows it to fit. I have not seen a performance muffler MADE TO FIT my Pathfinder after extensive searching, but it doesn't mean they don't exist.
This says 02-03, mines an 01, it would probably fit. I'm trying to avoid the one size fits all products. I have read where people tried some of these and had trouble fitting their sensors to the intake tube.

I have seen these, as stated in my last post, and asked if anyone had experience this the foam filters. Reviewing the ad again does not answer that question.

I can choose any means I like to research modifications. Somtimes I ask on open forums, like this one, for first experience with products or to share my own findings, however mundane they may be to you.
Thanks for your help, assuming that's your motive.

and returned it. It doesn't have a connection for one of my vacuum hoses, and I didn't want to jam it in the filter like they wanted me to. But if you have a drill, it should be easy to make one. It is a nice tube though.
The K&N should have the best gains, but I'd rather have a nice looking intake and give up .5 hp if at all.
That cold air box looks great. I wouldn't put a cone in my engine compartment without a good means to separate the intake air from hot underhood air and water. That box looks like a good piece. Most everyone who puts a "CAI" on the car are really just clamping a cone on the end of the intake tube, and all that is is a "HAI" (Hot Air Intake).

I have the SLR A.R.E. intake and it HAS shown a 9HP to the wheels increase over my baseline.
It is underhood and at the fresh air intake. Now, I know the physics and basics also, yet as I use the truck to get wet and run in dirt, putting the full CAI would just add to routing the water up and dirt into the Cone.
With using the stock air tube located behind and below the drivers light and
having the cone at 3" from the tube outlet under the hood, I get the benefit of both cold air and safe running.

How difficult is it to install the Air Lift bags? Can you adjust the pressure of the Air Lift from the inside? While driving?
2FastDre.
There is a Air Lift model, which comes with a onboard compressor to adjust rear end while driving. I did not get that model. I only add air when towing to level the load and keep the rear from dipping. It's a simple setup and has lasted over 3 years so far. I had to drop the rear axle and remove the coil springs to install the bags. Also, had to drill a small hole in the bottom spring holder to accomodate the air tubes. It took me half a day, would have been faster if I had a floor jack.
Nice pics. I am interested in putting a Dynomax on my HB. It is good to see you are happy with yours. It's a shame you got flamed when you were trying to let us see your progress. Don't let that stop ya from posting pics on your CAI. Keep it Up.
