I have a 2000 Mazda B2500 with 160,000 miles on it. I bought it with 9000 miles on it from the origional owner. It is a great truck. My wife commutes 55 miles each way to work with it. Before that it was my daily driver in northern Virginia rush hour traffic. Now,I use it to run around town and it hauls scrap for me on the weekends. The one thing I have noticed, my truck seems to have less umph. I need to replace the exhaust again real soon. I was looking at an aftermarket exhaust and maybe an air intake mod of some sort. I have found a nice exhaust system with 2.5 inlet pipe into the muffler, and a 2.25 mandrel bent tailpipe coming out-should breathe a heck of alot better. I am undecided at this time on an air intake setup. My question is this; will an exhaust and air intake mod require reprograming, or cause trouble codes ? My truck uses a mass airflow sensor, so I am hoping neither . Thanks.

Let's bump it and see if anyone wants to comment or not.

Personally I wouldn't expect much oomph from a 4 banger.

 

thanks for the bump. I have replaced the exhaust with a stock setup since the origional post. And I am not expecting my Mazda to run like my big block mud truck, just a little better. I have vehicles at work that are five years newer with less miles, but basically the same vehicle. After driving them and getting into mine, there is a big difference I can feel in power. My truck is a dog off the line. I would like to be able to pull into traffic with confidence that I won't get rear ended or ran over. A little passing ability would be nice for some of the two lane roads I travel. Thanks

you also got to look at it this way... 160k is a few miles for a engine, im guessing you took care of it and what not. but the motor could just be getting tired and needs some rest or a rebuild

 

yeah its had plenty of basic maintenance and care. It runs great and is very reliable. I guess maybe I should leave well enough alone. I just can't help to wonder how it would run with an aftermarket air filter and or air intake setup and a little better flowing exhaust. I guess for now I will be happy with what I got and save the tricks and mods for my mud truck.

Maybe the cat is getting plugged up and constricts the flow out at high rates.

 

i would start with new plugs and wires. even if wires appear ok insulation can detiorate and moisture can get inside them as well, plus they are subject to so much heat and abuse. an exhaust doesnt sound like a bad idea. i have been tinkering around the idea just so i can be able to hear the darn thing while i'm shifting because its so quiet. but yes i must add i dont think youll get much from a 4 banger either. at times i feel my 6 cylinder is too slow.

 

you have put 150k miles on the truck. You probably have owned it for 10 years......Now you want to "hotrod" the truck.......let me explain to you what is happening here....you are having a midlife crisis......... buy a "vette"

 

midlife crisis

 

you hit the nail on the head Powersmoked. But a Vette? Common man this is a Ford site ! I was thinking more along the lines of a Ford Raptor !

Rich

 

That will work!

 

cmon and everybody stop playing and tell me you would honestly a bad little stingray with a manual trans, strong motor, and set of pipes with fuzzy dice on the mirror that you would kick it out of bed or kick it out of your garage for that matter.

oh and the way i see it, a ranger is a little economical pickup that gets decent fuel economy while capable of hauling home a refrigerator or new tv. thats it! to build something as heavy as a pickup truck while it still being efficient are a big challenge. then ontop of that, to make it capable of getting out of its own way and still be within those parameters and last more than 100,000 miles without needing to be rebuilt is close to impossible. oh and then there is cost....
