  • After I sold this jeep i found that I had a cracked header... most cherokee and grand cherokees around this year will have cracked headers(exhaust manifold) If I replaced the header, this would sound like a T-REX compared to what its actually like.

  • nitrouspurger whyed they make u put a tailpipe on? i just bought a super 40 to replace my gibson catback and im just gonna put alittle downpipe tubing after the 40 and thats it. Is that illegal?

  • it sounds worse without the tailpipe, if you want to hear it look for my other video with the updated exhaust. its a downpipe exit connected to the muffler

  • What is a deeper sounding muffer with the stock cat, the super 40 or super 44? or any other muffler?

  • @Davidjagoe yeah man mine was cracked really bad, but a guy I know welded it for me for free. :)

  • did the Magnaflow Catalytic Converter add a little more sound? thanks im jw before i buy one,i have a supper 44 on my 4.0 and i want it to sound a little more throaty

  • Yeah. I'd go for it It's totally worth it the more flow the better gas mileage. Just remember on our 4.0's You need a certain amount of backpressure so don't get to much of a bigger exhaust the biggest i'd reccomend is a 2.5.

  • OK thanks, good to know then becuz I am running cat-back no muffler with 2.5" piping on my Grand Cherokee with the 4.0L and am considering the Magnaflow Cat for it.

  • yeah bro a High Flow or no Cat will sound better because of less restriction and most people bump up size of all the tubing on jeeps to like 2.5 bigger engines all the way up to 4 haha but yeah that's all it does is increase flow.

  • Does that Magnaflow cat give you a better sound or anything??

  • i have the flowmaster muffler but im lookin for a high flow cat. the deleted cat just sounds too scratchy so im hoping it will clean up the sound but hopefully it will still b loud

  • flowmaster muffler, magnaflow cat

  • i cut out my cat..the muffler will make it deeper but an aftermarket cat or no cat at all will make it louder
