i have recently just put on the bassani equal length headers and the bassani mid pipes. after everything was completely on i hear a small exhaust leak on the driver side but i cant feel any air from anywhere. and now when i start my truck after it warms it can barely stay running but when i unplug the MAF it idles fine. When driving at 40 or above it starts to have a bump in the engine. any thoughts on what is wrong?

 

#1 what codes is it throwing?

#2 you hear an exhaust leak, did you change the gasket, forget to tighten down a bolt or two?

#3 WHY are you unplugging the MAF when you messed with the exhaust?

 

No codes and checked and rechecked all the bolts and they are tight. MAF is just to try to troubleshoot
