1 7/8s or 1 3/4s?
well i'm getting my 3'' h-pipe with flowmaster single chamber set-up in the next week or so and am going to wait and save up for some kooks long tubes and put them on later. for now, its just a bolt-on car, but in the future i want to get a mild street cam. is there any disadvantage to going ahead and getting the headers with the 1 7/8'' primarys now? i wouldnt think so, but i just wanna be sure. thanks

I have 1 7/8 AR Headers on my car. I think they work awesome. I am still stock internals. My car responded very well. I gained a lot top and bottom end. Still untuned I gained 4 tenths and 3mph. from 110mph to 113mph I hear that the 01 and 02 cars like the 1 7/8 headers anyways because the ls6 intakes but who knows. Many people swear up and down that the 1 7/8 is too big but i wasnt going to buy another set of $900 headers if i wanted to supercharge my car. Good luck.

Bolt on a set of headers that are just too big and your torque peak will move so far up the rpm range, you'll never see it again--and you'll wonder why your new headers screwed up your motor.
Heres my source, I really hope this helps you out

I was forced to make this same decision recently myself.
I had been running the SLP 1 3/4" LT for the past few years, the time had come to replace them with a nice new set of kooks.
As already stated, what size was I to go with, 1 3/4" or 1 7/8" ?
I was favoring the 1 7/8" since my block is stroked to a 383,
but my main reason for getting rid of the SLP's was due to their bad ground clearance.
Being ground clearance, and wanting the best fit underneath possible (I'm also lowered), I decided to go with the 1 3/4" Kooks.
They were installed 3 weeks ago, and they are great!!! I don't know if I gained any horsepower or torque or not, but the ground clearance that I was after is priceless. I may have left some power on the table, I'll never really know, but I'm happy with my choice.
Good luck with your setup.

Thanks for that link, i know that for now i dont need the 1 7/8s, but once i get a mild street cam in the next year or so, would i benifit more from the 1 3/4s or the 1 7/8s? since im saving up to get stainless headers, i only plan on buying one set so i just want to do it right the first time

I'm not a header expert, but I would call kooks company to discuss what i've got on my car already and what i'm getting. I wouldn't see why they couldn't help you out over the phone right then and their to make an educated decision. I'm sure they deal with this all the time. Their number is 1-866-586-KOOK
Good luck

If you buy american racing headers that have high velocity merge collectors. These are very expensive collectors and they work. Its been proven over and over. Also the Ypipe if your going to run one has awesome ground clearance and has a REAL 2-1 Collector. I had a 3" end put on my y pipe for no extra charge. I can fit a beer can under the whole system. I also installed them on the floor of my garage with short jackstands. The only thing i had to do was disconnect the steering shaft (simple). I believe you dont have toon the 1 3/4 but thats what i keep hearing.

is there anywhere that you can get american racing headers for about 800-900 bucks? i'd like to keep it no higher than that and i'm getting true duals so the y-pipe doesn't matter.

Second. Call the sponsor having the sale and ask for your best price. My guess is no your not special and will have to pay as much as the rest of us for a premim header system.
Are you looking to buy just the header? That can be done, call the sponsor having the special. ARH arent cheap. Stainless steel is going to cost you money.

First question: 1 3/4. Bigger primaries are for bigger cubes. Kooks has stepped headers if you really want them.

but yea, i'm just looking for the headers, i think i'll go with kooks. the rest will be a custon h-pipe. well so far it looks like 1 3/4s will be more than enough for my car since the most i'd do to it would be a cam and posibly port the heads. i'm not looking to bore or stroke it. i appreciate the replies
