someone is trying to sell me shorty headers for a 98-99 ls1, do these fit the 2001 model, i dont see why not but just checking????

You car already has a nice set of "shorties" from the factory. Lol.

You may simply have to put block off plates on the emissions fittings if you wish to use them.

i wouldnt bother swapping them for shorties, people say the stock mani's flow jsut as well as shorties do, correct? if you're looking for the sound, i'd just take the cats off and get an ORY.

It would take some modification, and do almost nothing for an 01. It's a waste of time and money.

sorry to rob the post but i just dont understand how on a 99 z a set of bbk 1 3/4 shorties and a good y pipe dont do much more than a stock crappy manifolds i just cant imagine it?? would they help even with a cam?? everything is bigger and flows more? some people dont have $1300 for a set of kooks?

Well you will pick up a few hp. Its not a total waste of money to go with shorties. Its just that with the money you pay for shorties you could buy Pacesetter LT's.

Not everyone buys Kooks either. I cant be happier with my Pacesetters, they are really nice headers for the price.

lithium, i understanf that not everybody buys kooks but i need to have cats and pacesett dosent offer cats with a y-pipe, so id have to get a tsp y or a qtp y the tsp one has ground clearance issues and the qtp one???? my car is lowered and dosent have much clearance as it is, i understand that you will not get the same gain with shorties compared to longtubes but i think the bbk 1 3/4 shorties with my bassani 2.5 catted y would be a big improvement over the stock manifolds and stock cats and crushed y pipe, and with a cam it should flow alot better that stock???

Lithium

Crushed Y does not effect the flow as much as you think it should...still flows decent for stock.

I am not saying the the BBK's are a waste...some people are really happy with them and have seen decent gains.

How much you lowered?

shorties arent worth any money at all IMO. I would take them for free and only if I had no intentions of putting long tubes on the car.

lithium im not sure how lowered exactly cuse i bought the car like that but they are rk sport springs and i cant make it over a speed bump with out rubage on the y pipe and loudmouth muffler. what have you heard from gains from the bbk's i havent seen many posts about them do you have any info on them? links or anything? thanks alot.

Lithium

Yeah I ll see what I can dig up.

I just remember a guy on here a while ago, he said with the right combo the shorties can be really beneficial...or somethin like that. I ll dig it up for ya.

Theres some good info in these threads - https://ls1tech.com/forums/search.php?searchid=2583128

Still trying to find the one I am looking for...

EDIT - Now that I looked through all those threads it mostly people bashing them

MAC Midlengths are tons better than shorties, and they offer a catted Y-pipe.

We weren't talking about a 99'. The original poster has an 01'. You will see more of an improvement with shorties because your stock manifolds don't flow as well as an 01'. You can get the pacesetters for less than shorties and make more power. I believe TSP and pacesetter both make a catted y for the headers. You won't lose that much clearance with the pacesetters. TONS of lowered cars use the pacesetters.

You already lost your stock clearance by adding the bassani Y-pipe. Don't be a wuss!

Since you have an 01', I wouldn't bother. At most, I'd send them off to be ported by Hinson supercars for $75 and call it good. If you don't plan on ever doing LT's, then just port your stock manifolds, put some high flow cats on and call it a day.
