Another to do or not to do thread!
OK...heres my situation....headers will be off anyways for my clutch/diff change....right now i have 1 3/4" LG Pro Longtubes with offroad 3" X 32" primaries 3" race merge collectors, siamese XI have a chance to go to a 1 7/8 ARH LT's with 3" offroad X or Kooks 1 7/8 LT with 3" offroad X for little to nothing(trade mine plus a couple parts i got laying around and a tune)....would you do it?
If so how much power increase/tq decrease am I looking at....I figure with the spec twin disk clutch upgrade(lower MOI), 1 7/8 headers, and remove the MAF completely (my car is SD tuned) and replace with a Silicone smooth piece...no MAF Air Restriction....probably looking at 480 Rwhp....Should make it slightly easier for 10s.....heres my one day wishes....remove heads...mill more, thinner head gasket, diff/bigger cam, TEA do their upgraded TFS head port work...i think 500 RWHP would be attainable!
Headers wise...would you keep my LG pros or go with a 1 7/8 ARH w/3" Offroad X or Kooks 1 7/8 with 3" Offroad X?

Here is a post that I asked the same question to and the response I got from someone who has done just what you are asking. Needless to say I will be doing the 1 7/8's when the time comes.

IMO 1 3/4 headers are best for a 346na motor no matter how you cut it. Keeps the torque there for that little motor. Hell i'm thinking of staying with 1 3/4 headers on a 408 to keep the torque up and cam the thing up and keep things in perspective.

I would change the headers as well if it was me and you had those plans in the future.

A few more cubes but a good comparison to show that most of the low end mumbo jumbo is a myth.

Screw the torque, if u can get ARH 1 7/8 without breaking pocket, man jump on that without second thought.
