I'm sure ARH gave them one helluva deal on them as well.

Agreed. Copo is limited production but bragging rights are not.

I doubt they cared with the low production numbers of the COPO.

If I were buying new I would probably buy the 1 7/8" but I got a hell of a deal on 1 3/4" that I couldn't pass up.

With that being said, don't discount 1 3/4" so much. Did I make less HP than the average 1 7/8"....yes by maybe 3 rwhp. Now, I still have plenty of torque and when it comes race track where it really counts I've beaten plenty of Camaros with 1 7/8" and even one that had a supercharger and a couple that had good sized cams plus all the bolt-ons. Most of these guys fail to do the more critical suspension stuff that helps put the power to the ground and/or they have so much HP that street tires kill them. Either way when it can time to put up or shut up it was my car that took the win light.

Again, if I were buying new I would go 1 7/8". Why not...for the extra $100 or so plus the ability to go with more power adders it only makes sense but the difference is so minimal that I even turned down a set of ARH 1 7/8" headers. It wasn't worth my time and effort to switch them for a few HP. Instead I sold them and took the profit to put towards my gears.

We knew a similar write-up would bother some, but we simply can't change many facts. We do however have a few differences. We highly recommend the 2'' primaries as there is no downside, especially when modding beyond a CAI and Tune. We are open to debate, but our dyno results consistently show 2'' having a slight but solid performance advantage. (Dollar per HP, picking up the last 5 hp for $45 is very beneficial, especially if adding additional mods, that 5 hp quickly turns to 15)

Everyday we have a customer ask about what LT Headers to go with, so we had to make a thread. As a company, we can't point customers to another company's thread. We had to make a logical step by step thread to help answer customer questions and unfortunately that type of information will overlap in some areas, however we do fundamentally disagree with recommending 1-7/8'' headers to everyone as the standard best choice.

Just as if we make a general intake thread, you better bet we will highlight and recommend Cold Air Inductions, Roto-Fab, New Era, etc. 95% of the content are undisputed facts.

Just installed a set of Clear Image headers the other day. I bought them and had them JetHot coated for still hundreds less than most headers that are offered. Sorry but its completely ridiculous to spend more than $1k on a set of headers

Clear Image only makes bolt-on 1-3/4'' correct? Stainless Power is another option which is about half the price of ARH.

There is a possible downside, the fitment. There isn't much room on the driverside around the steering column. There are people that have fitment issues with the 1 7/8 headers as well. 2in would hit even more people. It has been noted that some engines have been known to sit one way or the other a few mm, which could be one of the culprits. Not everyone has the ability to lift their engine and move it over the few mm necessary to gain the room.

Ya that's right 1 3/4" primaries. But still about half the price of Stainless Power. So unless the 1/8" difference in primary diameter is that important I don't see a point in spending double your money.

BBK Ceramic Coated Long Tube Headers w/ Mid Pipes f/ Speed Unlimited-$599.99

Part #-B4540310

in my months of research, that was the best deal I could find. Granted this was more than a year ago.

We went with SLP Ceramic coated long tubes... they are doing great on our car noticed a big difference in power.. on top of that they already have the ceramic coating on them. We got ours at a steal for only $750 with the high flow cats. Has a thick flange so won't have any gasket problems literally bolted right up used factory gm gaskets
