I gained about 2-4 but I have a heavy foot by I'm deffitly cutting back

 

I cut off the old pipe under the engine near the oilpan and run SS pipe with a Borla universal2.25" in and out and a ss cat from Jegs(same size) the SS pipe is 2 inch from the local recycling center. I did this on all 5 cherokees in the family. If you go to XJ talk.com under Cpttuna"s Mods, you can see some pics. The original exhaust does not impress me and I wanted ss on there.

 

I did something a lil different with my setup.. Pacesetter headers which are split 3-1 3-1 tubes.. 2.25 piping down both sides of jeep matched up with flowmaster super 44 mufflers and 45 degree turn down/outs..

Has alot of drone but only while on the skinny pedal.. mpgs is in normal range maybe a lil higher but i cant tell because my speedo and tach dont work..

lost a lil torque but top end has improved.. im adding two high flow cats which should help with drone and low end torque.. Other than that couldnt be more happy..
