loves park, ill
yeah i had nicks tunes on my truck to begin with when i had the stock turbo and as soon as he plugged the efi in and started messing with it that was the biggest thing i noticed before i hit the go fast pedal! Ive also got 4 in duals that had a 3 in mbrp down pipe and it sounded great, my buddy has a flowpro 5 inch no muffler and its deff really deep tone
