HEADERS- 1 7/8 VS 2in?
Hey guys, I'm looking at a new build and is there a significant difference between the two? I'm talking about 15lbs of boost and more for this situation?
I have 1 3/4 now and was thinking about going to 2in, headers? Is is worth the cost for the change?

Me and arun installed 2" ARH on his vette and install was a breeze, fitment was damn great, heck i liked so much would be saving pennies for a 2", and iam only 347 cubes with 10 lbs boost.
Looking at 1 7/8 headers who upgrade from 1 3/4" did not loose anything under whole rpm infact gained torque and HP all over the graph.
Not much price difference between 1 7/8 and 2", i say go for 2" specially with 400+ Ci and over 15 lbs boost. 2" all the way.

On a 347 we went from 1 3/4 to 1 7/8 and picked up 13 rwhp-but the kicker is this-WE WENT TO A LARGER BLOWER PULLEY-from 3.4 to 3.55.
So we dropped boost but gained horsepower.

Very interesting. Undecided on whether to leave my 1 3/4 headers on my 347 YSI build and just put cutouts on it, or run 2 inch headers.
Headers are so damn expensive.

true 145 is slow I was trying to save you some $ but its your money so go for the 2'' headers brother I love you...
the car shifts @ 6000 so at that rpm its only like 750rwhp whats your point I'm really not a race track guy like you just a full body street car I have never tuned for the track I don't even have a lap top or Hp tuners and really don't care but I did run some mid 9s just playing at the track and I'm really sorry I shared that on here because for some reason you seem to have a problem with the MPH I ran with a bad pass never hooked like you rich dudes I have 4 kids and 4 rescued dogs that come first dude so........
and I'm not the one here bragging on my avatar (somewhere in the mid 9s) when you just got a got a car waiting to be blown???
I don't know how many times I had your back as a friend on here when you actually had a 9s car helping you but now you want to be unchristian like a through me under the buss all over this forum every chance you get to say my 9s car has a slow MPH I have gone faster than I have posted but really don't care to share anymore
I really wanted to go to the track day u set up in Houston but i will not be there for you guys to make fun and game with no one has ever helped my car get dialed in for track runs and I was praying someone at this rental would help me willing to pay for track tuning

Again, your car is fast. Go hit an early morning workout/cardio session to help relieve your stress level.

DOH!

Oh wait... That one nails me too... "You Bastard!" (Kyle voice from South Park)...
(Mine is the highest HP/lowest trap car on the forum...)
As for the headers, as much as I love the look/fit of my 2" ARH headers (although you still have to mod the AC line), knowing what I think I know now, I don't think I would swap from a GOOD set of 1 3/4" to go to a 2"....unless shooting for 1000hp or something..
I went from 1 3/4" LG Super Pros and they were an awesome set of headers to 2" ARH, it cost me about $700 to make the change after I sold my LGs, so not TOO bad but, I doubt I really gained much... I changed too many things at the same time though to measure any header gains. I would guess the gains were marginal at best on my set up.
If I was buying new and didn't have any headers at all, I would damn sure buy 2" ARH from the start.

I have 1" 7/8 to 2" stepped on my FRC and had a set of 1" 3/4 Kooks that were going on my Vert but just sold them and bought a new set of ARH 2". Still in the box! I am taking the 1"7/8 to 2" Kooks off the FRC and putting them on the Vert and installing the new 2" kooks on the FRC 427 F1x. The vert is 410ci n/a.
Shane has Kooks 2"
We have a set of LG pro 1" 3/4 on the yellow Z06 402 F1a making 900rw. It could use bigger bit not sure how much it will help.
If you can sell yours for a decent price then do it. It sure won't hurt

Plus on the 2 inch pull your A/C line off befor you put a set of 2 inch back on. Have to get your A/C LINE reworked and you cant get the line off the car with the 2 inch headers back on the car with the KOOKS. Robert

I run the 2" ARH...they are more money but fit like a glove with zero modification. I had my old 1 7/8 ARH out and new ones in in 2hrs on my back in my garage.
