i heard a lot of people going for longtubes instead of shorties my question is what the difference ups and downs of each one gains and etc..

 

shorty:
pros: cheaper, a tad easier to install, doesnt require shorty mid-pipe
cons: not enough power gains for the price

longtube
pros: nice power gains(especially in higher rpms)
consossibly a lil harder to install, cost a little more, requires a shorty midpipe

In the end, headers are meant for power, but shorty headers dont give enough to be worth the labor. Labor pricesrange from $300-$600, and even more if the shop isnt mustang-centered.

Verdict: LT's FTW

 

haha sounds good to me i have the full slp setup with stock headers so i plan on purchasing the SLP longtubes soon

 

I have the SLP LTs for over a year now and love them

 

Oh just rub it in why don't you LMAO

 

I will never do headers simpley because i refuse too take them off every time i have a tranny problem.

 

lol how many tranny problems do you have?

 

I was wondering the same thing

 

hp+dr's+stock driveline= its gonna happen.

 

Get long tubes if you get headers. I put on shorties and it was a pain in the ***. same work would of been done for long tubes.

 

For either with a 4.6L engine, be prepared to drop the k-member to get access to the header bolts and so forth. Also, be prepared for header leaks, as Ford REALLY does a good job in sealing the factory logs, but the aftermarket ones dont seem to seal as well.

 

Seems like people are really starting to get SLP LT's in here.

I think CSledd and I were one of the firsts... did we start a trend???!!! hahaha

 

lol I think so!!!

 

:stupid: Dropping the K-Member is really the only way to go. Once you do searches for header installs 99.9% of the time, people either wish they dropped the K-member or halfway through the install they do it. Dropping it should be no real concern and it is not difficult to do if you follow the instructions. Now, as far as leaks are concerned, the best thing you can do is get Percy's header gaskets. http://store.summitracing.com/partde...5&autoview=sku

I have used these before on my race cars and they are well worth the $40.
Keep in mind I spent that on header gaskets for a small block chevy. Headers are a sinch to work on there. So, I would be an idiot not to use the best gaskets available when doing my L/T's on a vehicle that is NOT easy to get to.

Just my .02.

 

Mike, thanks for the link. Now I have to kinda hijack the thread. Those of you with headers, what gaskets did you use, and how many just reused the stock gaskets. Ive heard they are champs and most dont get leaks, but I sure as HELL dont want to pull the K back out a second time for a leak...

 

Shorty Headers a dyno proven completely worthless on our cars. 3-5 RWHP at the MAX.

Where on the contrary, LT's make about 18-20 RWHP ALONE. With a full exhaust you could be looking at something like 25.

Definitely don't waste your time or money on mid-lengths or shorties.

 

I used the SLP gaskets that came with the LTs.. accidently messed one of them up (trying to install the LTs without dropping the k-member lol) and went to autozone and found some almost exactly like it. No problems at all

 

If you Drag race your car your gonna have clutch problems! there is no doubt that they make better power but you got to remember some of these cars are not full time race cars so is it worth it?

I have a good friend that owns a speedshop and he says when he sees a Stang come in w/long tubes, for tranny work he gets complaints about the xtra $$$$ for labor he charges vs. shortie or regular manifolds, due to the removing of the header in order to drop the tranny

I also have herd a lot of people complain about the lowered cars scrapping alot. but i believe that was on the earlier designs. Me personally iam happy with my FRPP ceramic shorties! no leaks ever! and i gained 11rwhp combined with a MAC pro-chamber iam sure the midpipe released alot of that power.

 

25 isnt likely. I have a complete exhaust setup and a tine and I'm at 255(on mustang dyno, which is actually known to be conservative). I highly doubt that with the stock headers and everything else, I was at 230.I maybe gained 15-20, but definitely not 25

 

If you are concerned about tranny issues including clutch replacement buy either hooker headers or flowtech headers, both are the same design and do not have to be removed when the trans needs serviced.

They do not however offer a catted mid pipe and require you buy their own mid pipe due to the connection between them.

 

i want proof, if this is so why the hell would they sell em and why are people buying them and happy with the results?
and i have percys seal for good gaskets they are great!!

 

See, another happy customer. I think they need to stock them on Mustangtuning.com

 

Screw that i would rather leave the stockers up there. I am near the limit for these blocks anyhow.

 

you could always get bassani mid-lengths....i hear they have decent gains and a new midpipe isnt needed...plus it wont be in the way of the tranny

 

and how much do both make on a car with a supercharger??

 

you need there shorter x-pipe to run mid lengths.

 

I think the best bet if you had the money would be to Put on an aftermarket K-member the same time you install the headers. Then you will have tons more room in there for other stuff and it saves weight. If you can drop $700 for a new K member then its completely worth it. Sound, Power, Weight savings, and Handling all in one weekend!:clap:

 

Yeah, but then the cycle begins. You need to buy a coilover kit and..since you are doing coilovers up front, you might as well do them in the back too.

 

Agreed, i'm pretty close too...But if you think about it, if you let the block breathe better and flow better it will run better and the chances of it blowing up is lower!

 

i just want to see some results of a supercharged car with shorties, midlengths, and longtubes...i guess i need to start searching..i just know that each one has a certain place they accel in better than the other
