1 7/8 headers vs. 1 3/4

I recently got an amazing deal on a set of headers..... they are 1 7/8" instead of the 1 3/4 inch... i have a cartek 2x setup.... however, stock displacement.... am I sacrificing anything with these???

You're gonna lose some TQ down low. Not sure that it'll affect peak HP though as compared to 1 3/4.

i was just kidding. everyone thinks 90mm intakes and 1 7/8 headers are overkill on stock cube motors. but i'm only bolt ons and am looking for a set of 1 7/8.

I'm thinking one I put 4.10's in, I won't mind the slight tourque loss, either way i'm thinking it will be better than the stock manifolds...

Like mentioned above, will lose just a td bit of low end power but not enough to be noticeable. You might get a little higher peak numbers due to the opened up flow. I got some 1 7/8 KOOKS that are about to go on and to compensate im gonna swap a gear and get a nice low end torquey cam to compensate

well, i'm thinking about slapping a procharger on in another year... but I just want to make sure... it isn't stupid to use these headers.... I guess what I want to know is, would it be worth spending an extra 300 dollars to go to 1 3/4????

also, what kind of time difference would I see in the quarter between the two?
