Opinion headers
I have searched the forum with unsuccessful results, so yes I have searched for the past week.
Here is my situation. I am in a position to buy headers within the next week or two.
I am definately looking to spend over 1k.
My main choices are
stainless works
American Racing
LG Pro
Kooks
I am looking to buy name brand not gonna contribute to some cheap knock off brand, but I am wondering if 1 7/8 with full 3" and no cats is too large for a 5.7. I am also wondering if ceramic coated headers are worth it. Also will a 3" bolt up to factory axle back.
I am seriously considering the stainless works as they are 1200 shipped to my house while the kooks and AR are well over 1500. Also the LG does not offer anything over 1 3/4 for the c5
Hoping to hear everyone's personal opinion and experiences. Thank you.

SoroZ,
If you want the best performance for your 5.7L engine you should purchase L.G. Motorsports - SP 5 134 - Super-Pro 1 3/4-inch headers, Random Technologies - 144-30000 - 3-inch, 100 cells-per-inch high-flow catalysts, and 3-inch X-pipe with whatever mufflers you want to run.
This is simply the best package for your Corvette.

Actually I am planning on making big power on the car in the next year, heads cam for sure, so the headers will have to flow pretty good.
but looks like I will be a 5.7 for a good couple years.
Thanks for all the opinions, seriously considering the stainless works due to price, and that I really do think 1 7/8 would work better for my application.

I would go with ARH's for the reason being that they have better fitment, seal better, and don't throw o2 codes/foul out o2 sensors like the LG's do. I would also go with 1 7/8" headers if your doing a cam and heads in the future or if you decide to change your mind and go forced induction

The only problem I have with the LGs are that they dont come in the 1 7/8 that I need, but they are good value and well known.
I would like the American Racing but they are a bit on the pricey side
I dont really have a price for the kooks either
The stainless works seem to be best of both worlds, decently priced $1200 shipped to my house but I haven't heard anything about the headers quite yet. So i'm still playing it safe.

The question is what cam/heads do you plan to go with? A mild street cam/head will work great with a 1 3/4. If you go with something alittle more extreme with all out N/a power in mind then yes the 1 7/8's would suit you (and by all out i mean the car barely idles). As far as 1 3/4's are concerned every brand you are looking at are great headers. My personal pick would be kooks 1 3/4's full header/x pipe system because they are the only equal length header for the c5 and come with spear tipped merge collectors for around 1200bucks with no cats. LG's are another great header and offer a street system without the spear tipped merge collector or equal lengths for around the same price. Regardless you are talking a difference of a few horses between one quality header system and another. What is more important is your tune.

Well I am looking at a decent sized cam, and milled heads, I believe the 1 7/8 will suit me best. Seems like I'm leaning more toward the ARH the price difference isnt that much, just gonna wait around for a deal I guess.

The cats that are typically supplied by header manufacturers have such a small effect on hp that it isn't worth the negatives. 2-3 hp maybe. To me the smell is quite annoying. It can also be a pain depending on emission testing and requirements where you live.
