1 3/4'' to 1 7/8'' stepped kooks with just cam - Will this hurt performance? Basically on their website that 1 3/4'' to 1 7/8'' stepped headers should be coupled with forced induction, n2o, or big cam cars. I will eventually be doing a new set of heads, or possibly n2o or procharger (but that could be down the road a ways). Thinking ahead I thought that these headers will be okay until I get those items installed.
However, a member on the board says I will loose lots of backpressure (if they are installed on my current setup of just a cam). I can imagine that I won't be utilizing these headers to their full potential, but will it necessarily hurt me a lot before I get the other items installed?
Essentially I am trying to gauge whether going with a straight 1 3/4'' piping is better than a 1 3/4'' - 1 7/8'' stepped (since I may not be getting n2o or FI anytime within the next year or so). What sort of gains or losses will I experience with either of those setups?

since you will ultimately need 1 7/8ths headers just get the big ones to start off with and be done with it. Even if it hurts power now which it probably wont at least you will save money in the long run.

no power loss will be seen......I ran the 1 7/8th's kooks on my stock internal car and didn't lose any low end. It also helps you out if you plan on further mods in the future.

Yep I have those same headers on my car with just exhaust and It doesn't seem like I lost any HP at all. I'm planning on installing a ProCharger within the next couple of months so thats why I ordered the STEP headers. You should be happy with them and save some money in the long run.
