LT question

[splitfinger09]

Are these any good? http://store.summitracing.com/partdetail.asp?autofilter=1∂=HOK%2D2290%2D1HKR&N=7 00+4294908216+4294908198+4294924667+4294840140+429 4923429+4294839039+400390+115&autoview=sku

Yes Hooker Super Comp are really good headers. Those have 1" 7/8 primaries wich is def to big on a stock cubic inch LS1. You want to go with 1" 3/4. For the price also check out QTP and Kooks.

Not too big for LS1 if you're sprayin.

I looked at these but i dont want to pay $300 for an ORY pipe

why is it bad to put the 1 7/8 primary on my car?

Im not going to be doing too many mods may a h/c package later on and i will be putting on a 100-150 shot of Nitrous.

Thanks!

If you plan on doing heads and cam and spraying definately go with the 1 7/8"
headers.

[INMY01TA]

The QTP y pipe blows anyway. I'd go with Kooks instead.

What if your planning on doing H/C only, would you go with the 7/8 or 3/4?

The problem is im going to get LT's with in the next month and the H/C package in probably over a year from now.

so why is it bad to have the 1 7/8" primary's with out the heads or cam?

It's not a bad idea. Actually I am surprised that others here have not seen the side by side dyno comparisons on the 1 7/8 and the 1 3/4 inch headers on a stock LS1. It's been done many times and has shown the the 1 7/8 inch headers don't hurt the motor at all.

As a matter of fact the motor made exactly the same power accross the board, with only a 1-2 HP increase in a few spots, but pretty much the dyno runs were identical on a stock motor. Shows that the 1 3/4 headers get the job done, but stepping up to 1 7/8 headers doesn't hurt anything on a stock LS1. And if going with a more radical setup or larger cubic inch the 1 7/8 headers would actually be beneficial at that point.

Thanks for the info!

Not a problem man. There have been 3-4 different magazines that I remember over the last couple of years that have done this comparison. I am sure a search on the internet would turn something up as well.

I'm curious why you say this I've heard the QTP y pipe is a quality product and I am considering this set up. I'd like to know what experience you have with it to say it sucks? Not saying you're wrong just looking for facts.

I have two friends that have/had them. Ground clearance is awefull and despite the merge in it they were very raspy.

They sure as hell don't look like tuned length headers, you can visually see that the primaries for the rearmost cylinders are shorter than the primaries for the front cylinders. Not to mention thats a ridiculous price to pay for header that aren't stainless. Get stainless steel, if you're insistant on getting them coated, have it done aftermarket.

[Wesman]

SLP's may be stainless, but it's 409 stainless, which is cheaper (and more prone to rusting) than the stainless most others use.

Exactly. Its pretty well known that 409 stainless is the cheapest grade of stainless, which is a ripoff considering the price of the SLP headers. For what they charge, it should be 321 stainless, or at the very least 304.

My XS headers are made from 321, which is aircraft grade stainless steel. I've been very happy with them.

I believe those are Corvette headers in the picture. F body Hookers have a different look. The price jack comes from those being 7/8s.

All the kooks headers are upwards of $1000

the QTP's look good, but i dont want to have to buy there $300 y-pipe


What would you recommend that is good quality for the price?

Ive looked at Pacesetter and Jet hots but im not sure about there quality.
I dont want to spend a fortune on headers.

Thanks

I think I might have a solution for you:

They are the headers that I have, and I've been more than happy with them. Install was easy, no cutting required. Just need to get the y-pipe bent downwards after the collector to help it clear the floorboard.

Thanks. I did some more searching and everyone seems to have the same opinion on the Y pipe the like the merge but clearance is an issue. I think I may just spend a few extra bucks and go kooks. They seem to have no issues with fit or sound.

I think that's a good choice. Can't go wrong with Kooks.
