Long Tube Headers - Pros/Cons
I am thinking about buying a set of Kooks LT headers for my Shelby. Does anyone have any issues running LT headers only without any additional upgrades such as ported TB or use of larger size blowers? I have heard from other Terminator owners that the addition of LT headers has yielded negative power results, but wanted to see if this was the case with others who may have tried this.09' GT500 #437/524 in Torch Red and #2615/3004 coupes

There have been a number of threads regarding the pros and cons of long/short tube headers. Do a search Bro Namath

I understand the trade offs between shorties and LT's. I was more interested in seeing if anyone had any issues or regrets with running LT's vs. keeping the factory setup.

Which ones have to be removed to work on the trans? If you leave them on, how are the clearance issues to work on the trans (clutch, etc)? Aren't some significantly easier to work with than others?

Recent articles in both major mustang magazines show about a 4/5% increase in hp/tq.
That cost about $1,800.00. Is it worth $1,800.00 for a 4/5% increase in hp/tq. For me it was, the folks at Kennie Bell don’t think it is and discourage there use. (They sell New Blowers) Tom@ARH just installed a set of there headers on his new stock GT500 and gained 20hp & 28tq with the stock Mufflers. (4/5%) [Tom sells headers but he don’t discourage the use of different blowers] The more Engine mods the more I think they must help.2007 Shelby GT500 Vert, Performance White.

I wouldnt recommend LT headers to anyone who doesnt have a KB/Whipple/TVS. The price and difficult install make it questionable in my mind for anyone not looking to make 700rwhp+. Its just too easy to make 500-600rwhp with the factory manifolds and factory cats. Many also find it difficult to get the exhaust note they are looking for with long tubes.

Dynotech don't have to be removed for trans removal

If you are going to do LT's why not buy full length and not mid length like kooks, I would not do any that are not full length. Like Robertt305 said dnyotech's do not need to come off for the trans and the install is not near as bad as people say, did mine a few weeks back and they are no where near as bad as I thought it would be.

Thanks for the great insights everyone. I knew there were two camps to this one. I also considered just buying the 3" Bassani catted system, but they complete setup with mufflers costs more than a set of coated headers with catted x-pipe. Anyone try that setup other than 5.0 magazine?

BTW, these were Swain coated and then painted with VHT.

Mike did you try to move the motor over before you dimpled the tube?
06-07-2010, 01:28 PM #16
Before I bolted the rack in, I checked it and found the some dimpling was required. I used a marker so I wouldn't go overboard. I'm happy with how it went.

I also installed a set of ARH 1-7/8 that were coated by Jet-Hot about a week ago. If you have the Lethal lowering kit which I do, you will need to bang on the primaries so that they will not contact the steering shaft. Not a big deal like someone already mentioned but it is a necessity.2010 GT500

I have the full 3" Bassani catted system on mine. it is loud and you have to take the headers off to do the trans or clutch. And each header tube is its own piece and can make it alittle harder to do. But I love them.
