I'm getting very bad mileage on my 2001 cherokee and am trying to replace the air intake, exhaust and oil. I can't find an exaust kit for the 2001 model other than the Gipson for $300, I really want to put a flowmaster 70 sieries but I can't find any pipe kits.
Does anyone have any suggestions on anything that will get me better gas mileage?

Hi , I have a 97 , 5.2 v8, , so this may not apply exactly. I had 110,000 miles on it and I was running somwhat rough and showed it had an o2 sensor engine light problem. I replaced both o2 sensors with little improvment. What the problem was, the catylatic converter was pluged up, as well as the muffler. I replaced the converter with a performance Flow Thru type , and I bought a Thrush flow thru , street legal muffler, which has a 2 1/2 in outflow. This is larger than the factory 2 1/4 inch. I took it to a muffler shop and had them make a 2 1/2 inch pipe to extend this all the way out. The muffler shop at first didn't want to do it, it is eaisier for them to put on a ready made 2 1/4 inch pipe. It was $81 for the custom made one. I want to ad a few footnotes. I bought the converter on eBAy, it was about $85 with shipping. About half of what it costs at your local auto store. I bought the Thrush muffler at my local store, it was only $21.00. This is not the loud one, it is the street legal one, and it is very subtle and perhaps just slight louder than your standard stock type. I am sure you wouldn't be able to tell the difference if you heard it. I was able to remove the old muffler system and install the converter/ thrush myself. I did have to have the muffler shop finish the tail pipe, and they also welded everything together. My miliage went up Drastically. It is a little hard to gauge because my engine was running rough for maybe 6-8 months, but I have owned 2 19 96 Grand Cherokees and neither of them ever performed this well ? My in town miliage is up 4 mpg. Sometimes 5 mpg. Please keep in mind that my car was running rough, I also changed plugs and the air cleaner, but on my real time miliage guage on my headliner console, I will get readings sometimes of 32- 34 mpg when I am cursing at 50 mph. It never read that high ever, on either of my cars. Hope this helps someone. Phil Barry, Dunedin, Florida
