Long Tubes??

I was under my car two days ago (doing the wire mod and changing the oil) and noticed my ORY is bolted pretty high up to my stock headers. It looks like I can't get LT unless I take the y pipe to get refabricated at a shop. It looks like I can only fit shorties or mids at the most for the current set up....is this true??? I want LT so I hope not. I can snap pics if I make no sense.

Going to long tubes requires a new y-pipe. Sometimes it's supplied with the headers (like SLP, FLP, etc.)...sometimes it's not.

so if I want to keep my y pipe I have right now, would shorties be what I am looking for or mid lenghts?

You would need shorties to keep the factory Y-pipe

but he's got a ORY....its not factory...

but to use a y-pipe that fits your stock exhaust manifolds, you would most likely have to get shorties to work with that y-pipe. unless maybe, you could get mid-lengths and be able to fab the y-pipe just a little to work with 'em...i wouldn't know for sure though....

I am going to give the shorties a try. What kinda gains do you see? I know it wont be as great as LT both HP and torque wise but for 200 bucks, Ill give them a shot.

i hear that the ls1 exhaust manifolds flow pretty d*mn well for stock manifolds and that switching to some new shorties won't actually net that much gain. i haven't actually seen any dyno's proving how little that might be....just what i've heard.

That's true for 00-02 but not for 98-99 their tubular manifolds suck.

yeah..actually when i posted that i had something go off in the back of my head telling me there was some exception to what i had said.....i just couldn't remember what.

thanks for clearin it up.

:)

Not to sure about the LS1, but on the LT1 they only gain 9 hp. Seems like alot of work for that, and I thoght the ls1 manifolds flowed better too...

Do not waste your time and money, Long tubes is what id get.IMHO

Some people can't pass emissions in their area with long tubes so in that case they are the wasted money.

i argue with many people on the subject of shorties. they do cost alot. however they are legal because they don't move the cats. you also should include high flow cats and y pipe to make a fair comparison to long tubes. the manufacturers claim 11 flywheel (thats both jba & edelbrock,i called them) horse gain from shorties probably 8 rwhp. plus add 9 for cats & y pipe according to random tech. long tubes will gain 20 to 25. when you make major changes pcm tuning is advised for maximum gain! good luck with your choice.

i'm with DANO on this one.

the LT vs shortie comparison is skewed.

LT's and the required ypipe gain you a solid 20hp

now the shorties ALONE will probably gain you 8-10hp, but that is still with the stock Ypipe.
combine a set of shorties AND an orp to that and you'd pick up probably a solid 15hp...

not a bad compromise to maintain the option to switch back to emissions legal in a few hours. and you won't (shouldn't) have the clearance problems.

Unless your driving a 00-02 car and already have the higher flowing manifolds.

It might be worth the few extra ponies to buy the 00-02 manifolds off someone who switched to long tubes if you could pick it up for like 50 bucks. 5 horsepower for 50 bucks isnt too bad.

i believe the long tubes will will more up on high end of the tach, and the shorties like to make more low or mid-range power. i take in to consideration your current or future head/cam selection. where will your shift points be?

thats not right....


long tubes make more mid range power....

a good set of mids or shortys will make more peak Hp....up in the 7,000 range

I had MAC mid-lengths and was very pleased with them on a bolt-on only car. Now that I have heads/cam, I went to LTs to take advantage of the added airflow. Only shorties will work with your stock-length Y-pipe. However, since you are running an off-road pipe it would seem that emissions aren't an issue, so why not go to at least mid-lengths?
