For about a year now I have been running some old-school fmf top end pipes. ( I ride in sand) They ran great, tons of top end and mid range. However, two weeks ago I cracked the back of the right header pipe, so I sealed that up and rode it this weekend. On saturday night I noticed that the right pipe cracked again this time so big it left a hole in it. So now I'm looking for a new pair of pipes for the dunes, (I've decided not to buy another pair of the same pipes) I'm thinking between CPI inframes, Pro Circuts or FMF SSTs. ( my banshee is stock ). I was wondering which pipe would be the better or close to the power I had. Any info is helpful.
