headers??? any help?

I just saw some perfromance headers for like 96-00 blazers anybody got sum or kno if they help alot? ??

Please ask questions completely and kick the short form words.

I basically had to reread your question 3 times to understand what you were asking.

Headers can be bought cheaply off of ebay and in my mind are not a good bang for the buck.

The stock 4.3L headers already flow very well.

thanks
