Header questions

Two questions:

1. If I am not planning on putting cams in, etc and just stick w bolt on mods to my 05 ls2, then should I stick w 1 3/4 headers vs 1 7/8 or does it matter?

2. Bang for buck I can get OBX headers w x pipe and cats installed for $1000.... Lg, kooks, amr equivalent will cost $1300-1600 plus install. So....are the OBX good enough? I'll probably save a $1000 w them

Thoughts?

Thx

you will find mixed reviews of them, imo if your not looking for max power or to set records then you will be pleased with them..

If I was buying new headers, I'd get obx. I found a killer deal on kooks headers with an install, and I just couldn't pass it up.

I'm with 1 3/4" American Racing Headers.. could I have gone 1 7/8", sure, but its negligible. PowerLabs did back to back testing on the swap and the gains were 0.7%, and as he put it was less than the accuracy of the dyno machine itself. I think he was about 575rwhp at that time IIRC.

OBX 1 7/8 + FAST 102 = more power and nearly same $ for just the "Name Brand" headers.

I'll have to disagree with that.

The headers work great. I love mine and the $800 savings is well worth it. The fit great with no issues.

Thats what i did, obx 1 7/8 and ported fast 102, total was $690 obx shipped and $990 ported fast shipped, total lil under $1700, same price for name brand and much mor power, I have had no issues with my obx and my builder and tuner were impressed with how they fit,look and perform. I say save your money on headers dont pay for names and no short cuts on any other mods. Like others said its a lot of post on this so search, you will find more than enough debates and a lot of different opinions. Good Luck

I have pics of mine on my profile if your curious

OBX or Texas Speed Longtubes are what I'd look at right now.

1 3/4 street series are for you. 1 3/4 are perfect for just bolt ons. No need to step up to 1 7/8.

These also carry a lifetime warranty

30+ years of racing experience built into each header.

Some things just really don't need warranties. Headers are one of those things, in my opinion.
