Searching doesn't hurt either. This topic was just discussed in depth in the last 2 weeks and the thread is just on page 2 of this forum:

^ probably picked up half of the new power just in the Y 
. Not a fair comparison as this was a H/C car. 1 7/8 would be a nice move if you plan on extra mods in moving more air later (i.e., heads, + cubes, etc). Might lose a little torque down low initially. Cam only car....I'm with Damian. This debate has been beatin to death...

This debate has been beatin to death...I think buying a set of Kooks or ARH only to step up 1/8" per primary is pointless, but they're not the only companies making 1 7/8" headers.

If the bigger primary headers were more expensive for just the size increase, I'd agree, but with TSP and Hooker (along with some others I don't know about, I'm sure) selling 1 7/8" headers for roughly the same price or just a little more than 1 3/4" headers, I don't see any reason not to pick up the 1 7/8". Sure, it's not necessary for a mid-power build, but it gives more headroom to make a little more power if someone decides to bump up to a bigger cam or better heads later on down the road.

Exactly!! If you have not bought a set of headers yet then 1 7/8 is the way to go. Definitely not worth it if you have 1 3/4 already.

Dont have a dyno sheet comparison but when i was cam only i raced two cars with my exact set up and won. Beat them both from a roll and a dig. The only difference was i was 1 7/8 they were 13/4. All three cars were ms4 cam only m6s.
