Stock exhaust upgrade

danthemanx07 · Jul 16, 2004

The stock exhaust on a 5.2 is 2.5 inches right? Is it worth the money and will it make any real difference to change over to 3 inch pipe with a new cat and muffler? or am i better off just changing out the muffler and cat and leaving the stock pipe?

Run a search on Kolak to get info on a 3 inch conversion. You will find that no one has complained about going with his setup.

it will "sound" cool and give a little better umph in high and midrange rpm (highway passing speeds) but, you will lose some torque value( 4wheeling no no). after switching to 3", i noticed a little mushyness in low rpm second gear..... what i mean is....... now, it has a little trouble deciding whether to go 2nd or 3rd at a mild speed of about 35-40mph and a little less snappy in that range unless overdrive is disabled. crawling needed a little more weight on the peddle...

i can't notice it anymore because of time, but did immediately after the change-over. but mostly it just sounds good to me. no real "noticeable" improvements. maybe im just not observant. i'd still do it again if i could just because i hate the way a stock zj sounds like a wind up toy.

hey dan, ask the jeep club!!! i am also getting a welder within about a week, and i have done 3 exhaust systems, and i have noticed a big power and fuel mileage difference. just ask man

well, maybe if you get that welder fired up soon, i go back to school on the 10th, i think i am actually going to be putting my lift on next weekend too, i want to get it done before i go back, the exhaust is on the back burner for now with school costs, but maybe i can swing it, thanks for the suggestion
