just ordered two of them and two turn downs to go with a tsp true duals x pipe. the reason for ordering that is because it has flowmaster 44 or 50's on it and i am selling them for obo if anybody want to buy them

just bought some magnaflows to replace my dynmax bullets, i must be getting too old because the noise was too loud and annoying to me, dont have the magnaflows on yet but im sure they will quiet it down some and they shouldn't hurt flow any beings they are straight through

Match your collectors to the exhaust tubing. If its 3.5" use full 3.5" duals. I've never over exhausted an LS yet. 347 ci with stepped headers from 1 7/8 to 2" with 3.5" collectors. Custom 3.5" y- pipe into a single 4". 6 speed on hose and rapes every time we hit the track.
