i searched but i couldnt find anything......i heard that stock ls400 headers are better than stock sc400 headers? is this tru? do u really get more power out of the ls400 stock headers on an sc400?

 

I really don't see why there wouldn't be a difference because that are the same motors. Only way I can see that is if there is more space to deal with in the engine bay. They have header flanges that you can buy for $110 that can start you off. The piping I will have to look into ,but my friend is making some so I will have to ask them.

 

Let me tell you, the headers on a V style motor is such a pain to change you might as well go with an aftermarket set and call it a day, rather than go with another OEM style for minimal power gains.

 

rush headers FTW...

 

Couldnt agree More!



S&S
EKT
RUSH

Thats pretty much it. The EKT are the closest thing to a 100% bolt on deal from what I have read. S&S are nice and fit well as long as you have a shop that can fabricate you some flanges to hok them up, I had a set and they performed very well.
Last but certainly not least are the Rush headers. They are a long tube with large 1.75" dia stainless runners. These should be top performers, dont plan on using your factory cats with these as they are made like traditional headers and the long tube design wont let you fit them. I have chose these for my current build, they are in route to my house as I speak, Cant wait! As soon as I saw the pictures of Marks (Blizzy) I had to have them!

 

alright thanks guys i'll look into those headers

 

Or someone could buy your old exhaust and not have to deal with the pain! :P
