Hey thank you heaps I bought a pair of 2.5 Magna flow metallic cats for my VT 5 litre senator 1998 so the magnaflow are good I herd from some people that if they heat up and expand the comb on the inside can get pushed and slowly squish the outer combs is that true or are the Magna flows fine and will they make the exhaust sound louder also I'm putting pacemaker try y on aswell I also have xforce 2.5 stainless system on aswell how do u think it will sound in combination Also the cats are 100cpi
