I was wondering if anyone had put an exhaust on their kj? I was into the tuner scene before my kj and i cant even hear my kj when im driving, i was just thinkin bout just a flowmaster muffler, maybe headers.

I have a flowmaster 40 series on mine....$75 at Advance Auto (in stock! 8) ). Sounds great...just the perfect sound level for me atleast. Alot of people suggest a 50 series (delta flow) and like that better because it's a bit quieter inside the Jeep. Since you liked tuner cars, I don't think the extra noise will bother you. In fact, I find mine a bit too quiet sometimes (too used to hearing V8s)...I can't imagine what the 50 series is like!

As far as headers go....I think there was some talk of JBA making some for the 3.7L. I don't know the price, but seeing as how the KJ isn't very quick from the get go, I would just slap on a flowmaster or catback system and call it quits. I'd rather spend my money on other things like wheels/tires or lockers. Check out the 4X2 section for performance mods.

just replace the muffler also no need to spend the extra bucks on the same size tailpipe. More money for other things that way :wink:

I think those clips are from v8 engines.. It sounds only a bit close to those on a KJ, revving at idle, you won't get anything.

It's OK. If I knew that it was going to be this quiet, I would have kept my stock muffler. Honestly. I have not seen any performance or mpg increase, I am strictly city driving, about 40 miles each day, and it has a weird way of quieting down or getting loud. You just have to find its sweet spot, and only then it is rumbling. I would have gone with 40 delta instead. Check my videos, you will get an idea. I will have to have someone hold the cam away one day and I can pass by to hear what others have been hearing.

I love my Flowmaster 50 series SUV. Perfect note, nice and low, doesnt sound to raspy(does alittle in higher rpms)..

Ive not really seen an increase in mpg though. Maybe 1-2 but its hard to notice.

I did figure up my mpg and got 20.3 after my trip home this past weekend. With speeds upwards of 75mph, I thought that was great. Ive always seen 20+ on the evic but Ive never figure it by hand and gotten over 20+, which I did this time.

Today I lowered the windows, and took her for a ride, what I realized is when you drive in 4x4 Full Time and have A/C on, it howls so much better for some crazy reason. I also realized it sounds so much better outside, since I never drove with the windows down at 20-30 mph with rpm around 1800. It is sounding at its peak at that rate. Remember I mentioned that sweet spot, it is about that. Slower you go, rpm is just not enough to make noise, faster you go with lower RPM, engine noise takes over and there isn't much discharge to make noise, But when you floor it, it sounds sweet. Again, was it worth $175? I doubt it.

I really would hate it if it sounded like one of those cheap imports that sounds like tin can pipes.. This sounds OK, again, not worth the money I spent on it.` If you can get it for $75 and get it welded for like $25 locally, go for it.

Get someone to do a drive-by with you standing on the side walk hyedipin.

It sounds better from the outside than you think it does.
