Which Headers to buy? HELP

i agree!!!! tti is the best.at least for my 68 cuda 360/380 crate engine and 4 speed. i bought the the whole system less mufflers. 2 1/2 inch with step down headers.flow masters off of e-bay. if you happen to have a mopar swap meet happening around you may want to talk to them there because of a 10% discount they offer at shows.it saved me 100 bucks plus the cost of shipping.
