i got my borla turbo mufflers welded on today along with a full 2.5 inch from the 3rd cat back. its nice and deep and i love the sound. its not as loud as i want it but thats probably because i sill have 3 cats. hoping to get rid of those soon. it seems to spin tires alot easier and get up and go when i step on the gas. i love it. the mufflers are straight threw so the only restrictions are the 3 cats and stock downtubes. is this exhasut setup good enough for a pulley and some intake mods?
