Unless you are exposing your undercarriage to salt, say in a South Florida environment, or Northeast winters, that would be the only benefit of owning the M&M headers.

Hp gains are the same +/-.
I can assure you, that there is a big difference in the quality of cats that were used. The M&M cats utilize the highest level 200 cell tri-metal design HJS has to offer. By the way, if you took the time to look at my profile you would see that I live in New England. Up here we have snow , salt, rain, oceans ect.. Not that my car ever comes out of the garage unless its sunny. :ah:
