What the Borla header & cat back did

[h.curtis]

Here is my report on what the Borla header, high flow cat and cat back did on my trip of over 2000 miles.

Last trip before putting new exhaust I got 15.4 mpg average.

Now...
My Jeep: '96 XJ with 4" lift, 31's and 5 sp (4.0)
Fuel: 87 octane
Mpg: 18.35

Also I have noticed a good low end torque increase. I don't have to shift as much going up hills and the truck runs with more zip. It sounds about the same as stock, but a little deeper and throatier. I am very happy with the exhaust set up. If I would have known I would increase power and fuel economy I would have done it sooner.

The only negative I have is the header is a bit bigger where it goes by the u-joint on my front axle. It hits if I go over a bit bump. This is probably due to my 4" lift and I need to move or get an adjustable track bar. I am going to look at that problem on Monday.

The install on this set up wasn't bad. I did it by myself in about 8 hours. I am not a mechanic, but have restored a car and do some stuff here and there.

Thought I would let people know how it went.

Take care,
Curt

"granted...different header and exhaust system but it all bolts/welds up the same"

get the adjuatable trackbar ASAP. My borla now has a small holw where I thought it would eventually self clearance.

The problem was the high flow cat. The entrance was too big, so I had to get a small pipe and fix the problem. I had no car to get it and a friend of mine picked up what I needed from work. I think it would have taken a couple hours less if I didn't have that situation. I also never took the intake off and it was a bit of a puzzle. I could cut alot of time off the job now that I did it once. I am used to putting together this project.
