Hey guys sorry if this isn't in the right place, but I couldn't find a thread with the aiv cat. The line that runs from the filter to the cat is split right where it should bolt to the cat. It sounds like a blowoff valve almost when I let off the throttle. I don't have to worry about emissions testing here so I've been pondering deleting it. What should I do with that line? Does it need to be crimped or sealed shut somehow? How much of that whole system can I remove? And lastly, does it make the exhaust any louder with the cat gone?
