Long tubes vs. shorties vs manifolds
Long tubes vs. shorties vs manifolds Obviously long tubes are the best but how much better than shorties, then shorties how much better are they than manifolds???
Any and all help would be appreciated.
Also hookers vs JBA shorties pros and cons.

Re: Long tubes vs. shorties vs manifolds shorties will give you 8-15 peak hp and will give you about 10 hp throughout rpm range longtubes re capable of lot more...I've seen 52 rwhp on a stock(no other bolt-ons...just more air intake) '02 ss camaro!!!! of course the headers he got cost him about 1300 bucks...on averge people see 25-40 hp out of hooker/jethot/jba/anything under$1000. its even more enhanced by the exhaust if you pu on a 3" or true duals.
as fr as hooker vs jba...I couldnt tell ya....
most long tubes require special work...cats or off road pipe... no cats mean ILLEGAL (unless they dont catch you
)...but longtubes will be louder and you will be watched more. with shorties you keep all your stock pipe no problem usually...which means less spending to make it work...and you keep legal(cats) of course you can always get custom tuning to keep emmissions legal with long tubes...but who wants to rob power to keeop legal... some longtube guys buy high flow cats and custom weld in y-pipe/x-pipe/true-duals so they can keep emissions legal....
all in all.....
YOU HAVE TO DECIDE.

Re: Long tubes vs. shorties vs manifolds Why not just go with LT's, are you trying to save money? I know that shorties dont make alot of power. If you want some nice headers for a decent price without getting LT's then get Mac midlengths. Thats what I have
Do you have a RX7 with an LS1 in it?

Re: Long tubes vs. shorties vs manifolds Yes I have an 93 RX7 with a 2001 LS1 and M6 in it that I want to get LT for but it isnt a guarenteed fit and they are expensive to "test".
I would love LT if I can get them to work.
If I could figure out how to post pics on this forum I would show you all some pics.

Re: Long tubes vs. shorties vs manifolds www.hinsonsupercars.com is suspost to be developing a long tube header for rx7's with ls1's in them.

Re: Long tubes vs. shorties vs manifolds I am currently thinking of getting shorties also eventhough everyone says they're useless, but i'm thinking of getting the new BBK shorties, they have bigger primaries than JBA or hooker (1 3/4 as opposed to 1 5/8) so you might consider those instead of the other 2. just a suggestion, tbyrne has them cheaper than anyone else

Re: Long tubes vs. shorties vs manifolds WhitePhonix, I tend to agree with...
JBA has the better of the current shorties (excluding the BBK which are unknow at this point) and only claims 8-12rwhp when I talked with them and looked at their dyno graphs. This was four years ago and on 98-99 cars. The 00-02 cars have better manifolds usually worth ~3-5rwhp over a 98-99 car did so I would expect the gain on a 00+ car to be very small if any. Others have posted 0rwhp gains on some cars that tried shorties.
The new BBK's might be worth a look with 1 3/4 primaries if one just had to have shorties. I asked JBA if they consider doing a header like that and they said no.

Re: Long tubes vs. shorties vs manifolds BTW did anyone notice the picture for the LS1 BBK 1 3/4 headers is actually a picture of either a set of LT1 headers or SBC headers?
Check out the middle exhaust ports.

Re: Long tubes vs. shorties vs manifolds I'm partial to Hooker shorties with Off Road Tubes and O2 simms. Hooker are equal length and balance the cylinders scavenging better (I think). The reason for that is I can slap the original cats back in and avoid any trouble with the LAW when I am on the street or sniff testing. As for power gains LT's are much better but have a lot more problems (clearance and stuff especialy if lowered. 
Re: Long tubes vs. shorties vs manifolds I think the best of both world's would be the mac's. Don't how they will fit on an RX7.
How is that coming out anyway. the handling of an rx7 with a ls1 motor must be fantastic.

Re: Long tubes vs. shorties vs manifolds That Chart has no bearing on the real FActs... IGNORE IT.
You cant just pop up some #'s... first of all your talking a bout an LS1 which responds differently than those #'s...cmon....the max hp was 171 vs 177??? is this a test??? you will see better torque and HP from long tubes. you will see gains from both... and a slight bit more torque and HP in the 2000-2500 range on shorties... But Long tube will do greater #'s everyplace else. It's more work getting em to fit. but you will feel a huge difference over shorties.

Re: Long tubes vs. shorties vs manifolds 93ls1RX7 do you have any pics of the car, engine, etc. Your's is the "newer" body style correct? Oh and yea get longtubes..I wouldn't bother with shorties unless you wanted to remain emissions legal.
Re: Long tubes vs. shorties vs manifolds I have plenty of pics but I cant for the life of me figure out how to post them on here and I dont have anyone to host. Yes it the new body style. I havent had her on the road yet cause I still need to finish my intake and get some exhaust put on.
Hinson has been talking about those headers for 4 months now and still no result.

Re: Long tubes vs. shorties vs manifolds soundengineer... Just so you know, in your first post, you mentioned about LT guys putting hiflo cats in their Y to stay emissions legal. Unless the cats are replaced in the stock locations, it is still an illegal setup. Not only that, but the only way you can legally change the cats is if your old ones are damaged in some way. Now by the same token, our cars are OBDII, so the emissions testing consists of plugging the computer in to see if the car says something is funky. No sniffer or visual test.
