Two Pronged Question: Guestimate HP/Weight Reduction...
Hi, I've got an '01 MN6 LS1.
Current/future mods are a Vortex cold airbox, Granetelli MAF (5% rich), and LAPD high flow airduct/coupler, FLP header, high flow cats, X-pipe, and Z06 titanium exhaust.
I guess since I haven't pulled the trigger on the exhaust yet, I'm looking for some prelim. guesses to help justify the 2K+ in parts and labor.
What kind of HP and weight savings can I expect...?
