fenderwell headers

any ideas on fenderwell headers .. im hoping that hooker makes a nice set because i am wanting to put a nice set of side pipes on my jeep .. i know all i need is the headers and a pait of purple hornies jeep glass packs with the bend int he end to go out the side at the back of the driver seat ... i was just wanting to know everyones ideas on it

 

i forgot to add i have fiberglass frount fenders

 

honestly, I have them on mine and they are not all that great.

Oh don't get me wrong hooker makes a good header but every time you go to drive it you smell like exhaust and it's louder. Some people say there is a power increase, I am not sure it makes a whole lot of differnce. I would rather have it quiter and not smell like exhaust.

But thats just me now, back when I put them on I thought they were great but times change.

 

lol i love the smell of burnt gas and the ringing in my ears ... comes from raceing anything and everything that has a motor ... first thing we ever did was port the carb polish and intake and hack the exhaust lol ... but anywho i really like the looks and loud sound of side pipes .. o just dont know if anyone here has some fenderwell headers and how do you think they would work on fiberglass... ? or near? or could i do side pipes with regular headers?

 

My Cherry Bomb daze are long gone. I've had enough noise fatigue, tinnitus, & hearing loss from work, bands, & open pipes.

For low end torque, you're better off running to a single thrush-type muffler w/some backpressure. You'll probably also find that your engine runs smoother with a 2 into 1 or at least a crossover.

My exhaust currently runs out IFO my left rear wheel because the installer didn't feel like fabbing a piece to cross at my transfer case. No other words for it - it sucks, especially in deep puddles & during hot weather.

Once everything else is completed this round of Jeep work, I'll run my exhaust out the rear.

I have fenderwells with cherry bombs and a fiberglass body. Trimmed inner fenderwells to clear header tubes, fiberglass actually touches tubes and mufflers ( if you call them that - too loud and I have full exhaust exiting behind rear tires) are within an inch to floor of fiberglass body. I have no heat related (melted fiberglass) problems with two years use. Also had them on a 73 cj5 304 with the turnouts in front of rear tires, tough sound, too loud.

 

yea thats what im trying to do is turn out in frount of the rear tires .. anything else i need becides fenderwell headers and mufflers with turnouts? and i do have a 73 with a 304 ... i wonder how loud it will be i head that purple hornies are really loud and i know that hooker headers are really loud ... i know each tube from the head is like 2 1/4 and i know from the collector back is 3 inch is there any poping from back pressure? any flames come out ? i know my friends car has flames comeing out of his glass packs and he kinda has the same setup i want ... looks kinda neat ... i dont plan on doing any trail stuff ... just mostly on road and maybe just dirt stuff .. beach and sand

 

Granted, lean is mean, but any "popping" or yellow flames come from an exhaust leak. When you let off the throttle, any leaks will draw in cold, fresh air, creating a lean condition & excess oxygen.

You should have a nice bubble down upon deceleration.

There is virtually no backpressure with your system. Remember, if exhaust can exit that easily, backpulses while under water will draw that much more water back into the exhaust ports. I personally like some backpressure on my cages, Jeep. Are there AR (anti-reversion) headers for autos/Jeeps, yet?

I have Dyno tests on my Shovelhead Stroker that prove hands down that a well-designed 2 into 1 exhaust creates much more HP and torque that a dualie. You should at least measure your exhaust pulse and install a cross-over at one of the pulse crests.

When I had dual cherry bombs exiting IFO my right rear wheel, w/my 6 into 2 headers, I used to shut off my ignition, pump the throttle a cpl. or 5 times, then turn on the ignition. It would sound like a dbl. barrelled 12 GA. and blue flames would shoot out about 3' to 4'. It was a surefire way to set off car alarms, store alarms, and to test the mettle of joggers. "When I was a chiild, I acted as a child. Now that I'm a man......I'm refining my toys for a man."

My 232 Clifford 6 into 2 headers have served me well for about 22 years, especially with modifications to the no-bolt system. I AM tired of fabbing shimes for the header spacers. My new rebuilt 258 will have the stock exhaust manifold.

Keep in mind that each header on a 304 is a 4 into 1 already, so comparing it to a 2 cyl is apples and oranges. A properly designed crossover will help your low end torque, but really won't make much of a difference peak Hp or Tqwise.

That said- I have had CJs with the side pipes, and friends have had them on 'glass Jeeps, and the 'glass will live, but they are incredibly loud, and get louder rather quickly, as the fiberglass fill burns out of the header muffler.

This is the type of muffler you want if you really need to get sidepipes out of your system-


I believe that Cherry Bomb and Hooker also have Jeep specific header muffler, you would one that is made specifically for Jeeps with fenderwell headers- trust me on this. (I have gone though the "I can save a lot of money if I just fabbed my own header muffles for my fenderwell headers", with limited success as far as time and money vs the aesthetics of the actual finished product goes)

 

I can ID with fabbing exhaust parts.

I see your point about 8 - vs- 2, but all internal combustion engines are basically air pumps. The number of cylinders doesn't matter. I seen the 24 hour Daytona Bandit Trans Am & other autos tested also. It all boils down to "Air in, Air out" in the most efficient way for torque & HP, not necessarily the biggest.

A local trucker's muffler trick was to take an old air tank and weld inlet & outlet pipes to it, then set it up in his stack. It made a good resonator.

LOL- echo can. (Don't know if you are old enough for the reference, but trust me I'm LMAO at the thought of one on a big rig)

 

them were the ones i was gonne do with i like purple hornies ... ...i guess im still young ... im allowed to play ... yea when i get older ill probely go stock ... or atleast stock with cutouts ... so i can play a little ... i dont plan on going into any water ... well aslong as i dont mely my fiberglass fenders ill be happy ... and i dont think it will be as loud as like a funny car ... might have a nice hot rod sound to it ... i cant wait to get my 1946 ford a-b flathead motor into a rod ... thats gonna sound real nice ... thanks for all the input guys ... and header choices ... i really like hooker and have had them on all my other cars.. i didnt know if them maid jeep fenderwell headers or not ill have to give them a call

thanks alot

 

Even better on a Jake Brake.

Have you ever heard of torque tubes?

I was born yesterday, but I've been up all nite.

Please explain "echo can".
An echo can to me goes back to early recording industry and was a can that was sung or played into for echo effect.

What is a fenderwell header?

I need headers or a manifold for my 225.

I want dual exhaust, going strait back, and I don't want to sound like I'm the young whippersnapper that I am.

If you have some links, please give me some links.

Thanks.

 

"Echo can" reminds me of a "thundermug" which was an old nickname for a bedpan in the days before indoor plumbing. (I'm not that old, but I've heard tales of such things).

 

I have the hedman header muffler combo. not too bad without the top on. with the top on, another story.

 

I have headers on Roman and I found out a couple a weeks ago about their vulnerability to rocks. I was traversing down a hill and I slowly dropped off a 24" "step" with my left front tire. The edge of the step ( rock) found its way into the area behind the tire and in front of the header collector and smashed into the pipes, denting them and causing an exhaust leak at the head. When I got home I had to re-weld the pipe at the flange where it had cracked. You could write it off to driver error but it is still an area where everything from the tires can possibly be thrown into the header pipes. I have since been thinking 'bout how to fab some kinda skid plate and/or other type of protection in this area. Maybe someone here has already tackled this problem.

 

My jeep has the 304 with headers made by hedman headers.Purchased the headers from the summit mailorder company for 115.00,best set of headers I've purchased yet.As far as mufflers go I run flowmaster 2 chamber 2 1/4 inch with turn down noise is not bad and the flowmaster can take the abuse of rocks etc.

 

I have Hookers 1-7/8" tubes and 3" collectors to Flow Masters on my CJ-5 w/ a 401. I had to do a lot of grinding at the header ports so they would match my heads. They sound and work great, but Headmans are JUNK, bad welds, lots of splatter, and don't come close to matching the dog leg head ports
