They have a sweet softail i'm intersted in. 2006 softail. 1 year factory warranty remains. Pipes, lowering kit etc... does this void warranty? will pipes pass emissions..? are pipes running too lean..? they claim they sell many bikes per month. Claim they buy/ sell only premium bikes for repeat business, etc. + they say they put on their dyno test, etc... Who are they. Would you trust them..? thanks gents.
