What muffler offset are you running? I plan on Spintechs. True duels with side exit.

Never had any rust, cracks, or rattles on mine. Guess maybe I should buy a lottery ticket.

When my truck ran...it had the Summit turbo mufflers with Dynomax headers. Sounded great...and cheap.

agreed, people who usually slag them have never used them. been running FM's on 5 diff trucks since early '90's. show me a spintech or whatever that will last 14 yrs under a 1 ton.
guess i better buy a lotto ticket too, for some reason my delta flow 50's dont rattle or rust either....bummer
