Hey guys,

I just picked up a cog system for cheap, its and 8# lower with a harley upper 3.25. My current SC is an MP....I've deleted all 4 stock cats and replaced them with 2 High flows, I have a silver bullet catback. I also have the JLP intake and Thunder Pipe.

My question is will the 8# and 3.25 and the MP be too much for my stock bottom end? How much boost will I make according to the chart provided by harley#358?

Thanks!
