Fenderwell Headers for CJ?

Looking for recommendations on Fenderwell Headers for a CJ-7. Hedman Headers are $139 in 4WD Hardware, very reasonable sounding to me. Anyone have any experience? I am going to change my in-frame POS to Fenderwells. In-Frame Headers Suck. All they are is a big headache.

Also, what have you used for exhaust off the Fenderwell Headers? 4WD also has the Hedman exhaust kit that includes non-baffled mufflers and side pipes. I can get a complete kit with Headers, Collectors, Mufflers, and Side Pipes for $239 in 4WD Hardware, all Hedman. Sound Good?

4wheeler.....I have the exact exhaust set up on my 5 that you are speaking of. I really like it and have had no problems with it. It's not exactly a torque builder since the mufflers come right off the headers, but your not losing much. But man does it sound nice! If you go with the fenderwell headers you may look up Jeg's and consider the purple hornies (mufflers). If I remember right you bolt them right on to the collector as oppossed to the muffler kit that 4WD offers where you have to weld them to a reducer that bolts to the header. Either way they sound good!

Thanks for the info! Got some good replies in the "CJ Forum" on this topic also, and was also recommended that I look at mufflers (ie. Dynomax) that come with bolt-on-ready collectors. <img border="0" title="" alt="[Wink]" src="wink.gif" />

I have the hedman htc fenderwell headers, they're expensive but they are nice, good quality, they lasted through the winter with no rust.
They run into a set of header mufflers that run out under the door.
I want to get rid of them and switch to in frame headers and an exhaust out the back. what problems have you had with yours that you dont like them.

Bulletproof, if you are still set on switching, maybe we can work something out... <img border="0" title="" alt="[Wink]" src="wink.gif" />

However, the problems I have with the in-frame headers (and I don't even have the Jeep "roadworthy" nor have driven it extensively yet, aside from around the neighborhood troubleshooting) are the following:

1) Have to remove the right header/disconnect the exhaust to change your starter.

2) Left Header rubs the brake lines/proportioning valve area...not a good thing to build up high heat/"boil" your brake fluid, not to mention eventually wearing a hole in the lines, LOL.

3) Left Header is making it a real B*tch to adjust the clutch push-rod...it's in the way from every possible angle.

4) Not a big deal, but some of the collector/flange bolts are a "challenge" to get to, due to the tight fit/location where they fall.

Those are the main things, but I generally just don't like them being in the way of almost everything underneath iin that area. I like to have a little room when I work on things, and they seem to always be in the way. Don't get me wrong, I think the sound of rear-exiting exhaust is great when you have a quality setup, I had one that was downright mean on my last CJ-7, but it was an Inline 4.2 and I didn't have nearly the "interference" problems as this.

Let me know what you decide.

I just put a set of Hedmen Fenderwell headers on my CJ. I like them. My problem was I have to run cats for inspection. I put 12 inch glass packs on and they were LOUD! After a few looks from my neighbors I put on a set of Flowmasters.(It sounds nice but looks a bit funny with low tailpipes.) I'm now looking for short glass packs that are "more packed". I got tired of the exhaust banging everything under the Jeep with the inframe headers.
Good Luck

4wheeler- I'm not sure what im going to do about them right now. I'm leaning towards just replacing the mufflers with something of higher quality( quieter sound) i have those 4" header mufflers that came in the kit, they are friggin loud and obnoxious plus the are about ready to fall off!
I'm considering those purple horndogs for now but looking into supertrapp mufflers also, you can adjust them for power or sound, just havent found any to fit yet.

Check out Dynomax Super Turbos. They have one muffler that will fit perfect .... they have a 3" flange plate to bolt directly to your collector, centered on the muffler on that end, and the pipe exits on one side of the muffler at the other end, allowing the muffler to be flipped either way to fit how you like best. Total length is about 24" from pipe tip to tip, so it would be even shorter once it is all mounted.

I talk to a guy in my other post in the CJ Forum about it, and he has used tham for a while now, and loves them! Check out the other post on this in CJ Forum. <img border="0" title="" alt="[Wink]" src="wink.gif" />

Thanks for the pics. Are those the Dynomax ones I was describing? If so, no offense, I don't like the fit. Is there any way to fit them so they dont hang down (more level)? Those are just asking to get ripped off or rip off the headers.

I know I just saw a pic this morning of a guy's CJ with Fenderwells, and compact Flowmasters that tucked up nice and level. Ever see them?

I think they are the dynomax ones you are talking about. I could not find anything else smaller to fit in there as well as connect to the header. Since I do not have any rock crawling areas in the great flat state of Illinois the depth that they hang was fine for me. I see mud and trail riding but no rock crawling. They do not hang any lower than the skid plate. They only cost about 45 bucks each so if I do rip one off It would not be the end of the world.

If you do get a part number for the compact flowmasters I would love to get it and take a look at them.

I just got done doing research on <a href="http://www.flowmastermufflers.com" target="_blank">www.flowmastermufflers.com</a> and <a href="http://www.dynomax.com" target="_blank">www.dynomax.com</a> and they have SO MANY! They have some real small compact ones out there, take a look! Once O sort it out, I'll post the smallest Flowmaster and smallest Dynomax I can find. <img border="0" title="" alt="[Wink]" src="wink.gif" />

I had nerf bars on my last CJ and saved them for this one I am doing now, but They won't work together unless you do some funky stuff. I've decided the side pipes have more benefits than the nerfs, so I am leaving the nerfs off. <img border="0" title="" alt="[Wink]" src="wink.gif" />
