ok well i had my 2.5" catback on with a stock vr6 cat. that has the metal screens so you can't punch it out easy short of cutting it in half. well so i had this cheap 2.5" cermanic one that i have in a pic somewhere. so its smaller so less turbulance more power+gutted. so i had to cut the bolts off cuz they were rusted on and i didn't wanna mess with them so i get the 2 lower ones off the top one i used a air hammer. so then i cut it off the pipe and un hook the o2 sensor. i pull it down and set it down and start putting the gutten one on. thanks to my buddys lift it took no time and hes got a welder so nice new beads. but so im looking at it as hes welding on the gutted cat and i look through to see nothing but ITS FREAKING GUTTED!!!!!!!!!!!!!!!!!!!!!!!!! its done nice 2!. so i had a gutted cat on there. no wonder i was getting a CEL for the cat. but i only got it on highway trips. around town i don't have one. so i still don't have a cel with a gutted cat thats cool to me. but i find that stock vw cats have 2.5" in 2.1/4" out. so now i have true 2.5" all the way. i didn't notice anything but a nicer sound and the car does rev smoother and faster. but yea so thats what happend tonight working on the jetta.
