My exhaust system consists of Mac mids with ORY and a stock catback through a chokemaster. The dyno numbers in my sig are with the cutout open. My other mods are a baby cam (212 218/522 529/114), LS6 intake, SLP 3.73's, SLP lid, ASP pulley. Was wondering what kind of HP numbers I can make by swapping out the Macs for some LT's and maybe either a catback or true duals? Also based on mods I listed, what might be the track time it could run?

 

was seeing what others thought because if the power increase wont be that great I may just stick with the mids and just change my muffler or something
