  • HEY! LOVE the 4 banger. Got one too. I have a 95 4cyl, on 33's. Aem intake, TB spacer, and 6 cyl throttle body. I was thinking of getting a dyno,ax pipe, and a flowmaster. Is there an increase in power? Is it annoyingly loud, (dont really care :) thanks

  • @ZurichONE95 i didnt notice any power gains, and its not annoyingly loud at all its got a nice tone to it, but on the high way the tires drown it out

  • did u take the cat off?

  • nope, still got it on there

  • were all the 4 cylinders in jeeps fuel injected? i know the 4.2 was carb and the 4.0 replaced it in 91 but is an 87-91 4 cylinder wrangler fuel injected?

  • yeah all the 4 cyclinders were fuel injected.

see all

  • is that a delta flow or american thunder?

  • @ZurichONE95 yeah, I have a cold air, my muffler just popped and I was going to replace it with a flowmaster 40 series....it doesn't sound irritatingly loud in the video. I really like the growl it has but I was wondering if in person it was kind of obnoxious.

  • @MattRT91 hey, sorry for the late reply. youll be fine bro. I have lower gears than that! im pushing swampers 33. but i have a few upgrades like intake, throttle body from 6 cyl, and maganflow

  • @ZurichONE95 hey i just got a 4 banger and was looking to move up from the itty bitty tiny little 29's...it has a small lift and honestly looks kind on it's "tippy toes". If I where to go to 31's or 32's would i instantly start hating my life on the street and highway or would I do alright. It has an ax5 with 4.11's btw :/

  • Reached a lil problem. I got my Magnaflow cat today, and m getting a cat back kit. BUT! My stock exhaust is welded on? I thought it was just clamps. What did you do?

  • i think that the carb was still an option in 87 for the 4, i remember reading that somewhere....
