headers for this 427
 

for my 427 build in my 2000 camaro, i think im goona go ahead and spend the money on a new headers now rather than later..... most likely peaking at 68-69 and shifting at 73-74, mamo ls7 heads, msd airforce......i think im goona want a 1 7/8 stepped to 2 inch header to help with my midrange torque goals that the cam will be specced for. ideas? i dont need emissions, and wouldn't mind a wideband tho.

i wouldn't mind trying TSP or speed engineering simply for the price benefit, but i haven't found any dyno graphs comparing there headers to the $1000 big boys.

side note, hooker on their website says breaking in an engine with ceramic headers will ruin the coating....thoughts?

anybody know of a place to just get ARH without the y pipe? every time i see them its a full system

Call ARH; they'll tell you what's available.

its sunday......duhhhhh.....jk. yea i planned on it tomorrow but im impatient and want the satisfaction of an internet response

i emailed him earlier, but he knows its sunday too lol

how did they fit? the only 1 7/8 stepped to 2" i found are kooks. i really like the stepped idea

yea from what i have read on this site, again the bad fitment could be from mount issues, but basically no issues with kooks or ARH. TSP are 80% no issues, 20% minimal issues, nothing major, speed engineering 50-50, hooker.......a few major fitment issues, not worth chancing, hooker isn't far off from ARH pricing, especially if tony is a dealer. pacesetters.....what the hell is a pacesetter......

Treed. I was gonna say the same. When my headers rust through this is my plan

What Chevelle said - 2 inch primary.

427 with Tony Mamo heads, Tony Mamo ported MSD intake, Tony Mamo spec'd cam - torque wont be an issue.

With that in mind, I'd ditch the stepped 1 7/8 to 2 inch for mid-range torque idea and just go 2 in primary for max power.

tony said he has sometimes seen loss with stepped headers and advised for 2 as well

Get cooking with KOOKS headers!

i call tick today cause they had a 1 day stupid low sale on kooks, pretty sure they were higher than normal lol

ARH might be an option?

One of the two if your looking for the high end headers. I'm curious about the TSP headers for fitment as I have 99 Camaro strip car build that's been put on the back burner for now and will be needing some headers one of these days.

yea im probably going with ARH cause thats what i was leaning towards anyway.

from what i have read tsp are very similar to kooks, which basically have no issues

I went with KOOKS for the headers and their off-road dual exhaust set up and everything fit nicely and not to difficult to take on and off either. I've never ran this thing with open headers and am anxious to hear it once I get the new heads on it.
