What are the best headers in terms of performance. I don't have to worry about emmisions, but don't want to have a bad scraping problem. This is for a L98. What are the power differences between shorties and LT's?

 

The power difference is where in the RPM band the headers help out best.

 

ive heard a lot of good things about the slp headers and edelbrock. from what ive been hearing its really a matter of price.

 

Best for the money would be slp coated headers, at least for shorties.
You can get them in 1 3/4 as opossed to the 1 5/8s primaries of all the other headers out there. Plus being stainless steel and coated they will never wear out. The non-coated run about $600 a set. www.slponline.com

 

Why coat stainless headers?

------------------
No guts, no glory.

 

Heat. It passes through corrosion resistant steel much easier than it does through a ceramic coating.

so...non coated stainless headers will always look good right? They won't turn rusty looking? Please let me know so I can jump in on the GP real quick!!

I don't know about SS, but chromed headers blue over time due to heat and look kinda funky. Not sure if heat has the same effect on stainless though.

 

only drive yuour car in the summer stay outta the rain anbd elements and you'll be fine

 

They will not remain bright like as-received. They will turn brownish over time.

Someone posted pictures of non-coated TES and SLP a little while ago. Look through the posts and you can see for yourself.
