I have an 89 k2500 eclb 4x4. Truck has a 5.7 and 465 combo. I just ordered flowtech afterburner headers and was getting ready to order the matching your pipe when I thought about the fit up on this truck. Will these fit with the manual transmission? Bellhousing? Linkage? Etc. Also I understand these are not the best headers on the market but this is a stock engine that will never be built more than bolt ons and it is also a work/ play truck only not a daily driver. I was just curious if anyone had used this combo of exhaust components on a similar drive train setup??
