I'm wanting to get more low end and pull out of my 97 750sxi. I know a factory b pipe can cost me a pretty penny, and I have a guy that is gonna sell me a coffman pipe shipped for $225. I just wanted some peoples info on rather the factory b is worth that much more than the coffman or if I should just settle for the coffman...............,so coffman$225 vs factoryb$7-800?
