how many people are running the big tube headers
also does pacesetter make the 1 7/8 headers
also should i do ceramic coated or just painted headers

No need for bigger headers unless ur making over 500hp, bigger cubes.
I believe pacesetter only makes 1 3/4 for f-bodies.
Coated if you want to keep the temp. down under ur hood.

Get Coated ones..I bought Texas Speeds 1 7/8s because one day I plan to use them!

I would like to dyno my Cam set up with 1 3/4 vs the 1 7/8s to see the power losses or gain and the curve..

I am running kooks 1-7/8 race headers. I am not making a ton of power right now but once i get there I don't want my headers holding me back. No need to buy something twice. Get the 1-7/8 and you will be set for future upgrades. Yes.. there will be future upgrades! You won't be able to help it!

ive also tossed around the idea of ditching my 1 3/4 pacesetters for 1 7/8 hooker longtube headers or possibly ARH. also, wanting to hear peoples experiences who made the switch and if they gained much? or how much faster did they run?

1-7/8 headers have been proven to make more power up top and make the same power down low as 1-3/4 headers. even on a completely stock vehicle 1-7/8 make more power than 1-3/4

another vote for 1 7/8 TSP's ..There is a guy in my neighborhood with a pretty identical setup as me(we are both cam only) and i put down 10 more rwhp than him and i have beat him by as much as 2 cars from a roll. we are both m6 z/28s but he has hooker 1 3/4 and i have the TSP's..just my .02

I bought KOOKS 1 7/8" for my set-up because I know my future mods are going to call for it. Hell even now on my 346 after all the research I've done I believe I'll see better numbers then with 1 3/4". I say 1 7/8" all the way!

TSP 1 7/8 here fit good with poly mounts I would recommend them.

Hooker 1 7/8 here. Do it if you plan to mod further the engine.

Here's a great article discussing the merits of stock manifolds vs 1 3/4 vs 1 7/8

^^^^ Great Article ^^^^^ looks like the power gains are very negligible between the 1 3/4 and 1 7/8's but much better than stock which should obvious.

i have 1 7/8 QTP because i got a killer deal on em (325 new)
definitely get coated!
i dynoed 325/342 with these headers and ran a 13.1@110 with a 2.1 60, if that helps

oh and the car sounds like a stang with the catted y (yes it sounds that good)
