Bought it from a friend. Custom x-pipe from a muffler shop. going to the muffler shop tomorrow to get it put on. i would do it myself but i have to get the ends welded on to fit on the catback. It also has cutouts on it. got it for $60.
Yeah, V6s fire evenly so they don't need any sort of crossover pipe. it just is good to have in case one piston loses compression. Also a bit different sound.
I am getting a nearly new mac X-pipe from a friend of mine who had it on his mach 1 but it was WAY too loud so he's installing a prochamber (he has an auto with SS mac cat back and 4.10 gears, so it's really tough to bear on the highway)
