Could some one hook me up with some literature on the TRD
headers. Where I can get them, how much, and what kind of gains they produce? On a side note, I heard that the original down pipe off the original headers was the 2-1 part of the 4-2-1 header. Is that true?, and if so, would it make more sense to replace the down pipe, so that it would go 4-1-1 with an aftermarket header and not 4-1-2-1 (keeping the stock down pipe)? And lastly, which brand of exhaust wrap is the best to put on your headers, and how much?
I know this is alot, but any info y'all can give me would be greatly appreciated
