There isn't really a best, more of a preferance. If you want power either the SLP LM or a xpipe setup would be better into consideration. With the SLP LM you will be loud, raspy, and not ver good sounding. Next i'd consider the Hooker and GMMG.

I went from a 3 inch cutout flowmaster to a SLP LM and i kinda regret doing it. Flowmaster isn't the best for performance but the sound with a ORP and cutout was the best, even with the cutout closed it sounded very nice.

 

yes borla is def overrated , on a stock car it sound decent, gutting the catt and no plate sounds like doo doo,.....i really cant imagine it with LT headers ORY and no plate , thats basically straight through like the LM and it will sound just a $hitty

Dustin has it right
GMMG 4 life , specially with jethotts and ORY ::
