Do you think that it would actually detrimental rather than beneficial to get the Stainless Works Headers With 2" Primaries And 3" Catted instead of the Stainless Works Headers With 1-7/8" Primaries And 3" Catted because of the size? Both cost relatively the same.
Consider your long term goals for your car before deciding what you buy because you can handle a lot of HP with a 2.5" exhaust. Also, while it is relatively rare, there could be a clearance issue on the headers so a 1 7/8" vs a 2" buys you an 1/8" of clearance right out the box.
I don't have a header or exhaust size preference either way. I just think knowing where you are heading with your engine will help answer the question more clearly.
